1. What You Will Learn: Now, have you ever wanted to paint a scene with a beautiful dune and beach and scene in the background? But you find that the results are really quite flat. You're not getting the light, you're not getting the mood, or even something that's just colorful and attractive. Now, it doesn't have to be that way, of course. We can paint vibrant sun filled beach scenes. And this is what this tutorial is all about. It's how to use your color to create a strong light effect. And a light effect is simply the impression of light. You get that sense or that feeling of the bright light. Things like color temperature and light and dark color and brushwork and how you use that color like an impressionist, really make that color sing so your painting is vibrant and beautiful to look at. We're going to show you exactly how to do that. And in this demonstration, I'm going to be looking at this scene. It's a beautiful scene with lots of potential. Maybe it looks a little ordinary in the photograph. I'm going to show you how to bring that to life. Just using some acrylic paint, your brushes, and a little bit of use of color magic. I'm Malcolm Dewey, and I'm a professional artist painting in various mediums in an impressionist style. And this short tutorial is going to help you transform your painting. Let's begin. 2. Materials: Let's have a quick look at the materials I'm going to be using. Nothing too complex. As far as materials go, I try to keep it quite simple. I'm going to use a panel like this. This is just MDF panel. That has been seed, and I'll also coat it with a toning color. Materials wise. Let's have a look at the paints. I'm going to be using golden open acrylics because they take longer to dry and I prefer that with my use of acrylics. Now, the colors is pretty much my standard palette which relies on warm and cool colors of the primary colors. So let's start off with titanium white, the standard white color. And then as far as yellows, a cool white, I've got cadmium yellow primrose, but you can also use cadmium yellow lemon. Cadmium yellow, dark. That's my warm yellow. I have convenience colors yellow ochre and burnt sienna. Then the blues, there's a warm and a cool. The warm will be ultramarine blue. The cool is cerulean. You can use cobalt or a sky blue, anything like that, a cool lighter blue. Reds, I've got Naphtal red light, and has the cool red quacrodone red. Zarin crimson or magenta will also work fine for that. Now, these are artists quality paints, and that means they are a bit more expensive, in some cases, quite a lot more expensive. And therefore, I also use for student acrylics Amsterdam acrylics. They're excellent. W straight out the tube, nice and soft, ready to go. The same principles are warm and cool of the primaries, titanium white and yellow ochre burnt Siena. So you can use these with confidence as well. Brushes also fairly simple, mostly long flats, size four, size six, size eight, and a rigor brush for small shapes. These are Dawni brushes for acrylics called Krilla and this is also a Dalarowi short flat, which is nice for some big shapes in the beginning. And that's about it. Quite simple with the brushes. I use a tear of palette like this, but any appropriate palette will be fine. When I'm working with this with acrylics, and if I'm worried about the paint drying, I'll use the spritzer to atomize some water over the paint that keeps them nice and soft. Have plenty of clean water, have plenty of tissues or cloths to wipe your brush off. I don't always wash the brush in water, but if you do you must dry off the brush to get rid of cess. Water, otherwise, your acrylics gets too thin. What I often do, though, is after painting, I will wipe the brush, pick up, clean paint, and carry on. And that works fine, too, in most cases. Nice to have is a color wheel, one of these color wheels, and it might just help you with color selection or mixing. And a notebook and a pencil just to prepare and do some a studies to help you just plot and plan your composition and ideas. And the pencil can be used as well to draw out composition on your painting surface. Right? That's about it. Let's get into the painting. 3. Three Important Techniques: Some of the concepts I'm going to be using in this painting. Let's look at three of them, starting with color temperature. Color temperature sounds complicated, but what it means is what is one color compared to the other as far as temperature is concerned. And that, of course, means is the color warm or is the color cool compared to the other one. For instance, a cool red like lizarin crimson is going to look cool next to a warm color like orange or yellow. But put the lizarin crimson next to cobalt blue. And the lizarin is going to look warm. The cobalt blue is much cooler. So everything's about how we put colors together, and that's the secret. How we put those colors together is everything in an impressionist painting. If we put warm up against cool, then that warm really looks warm, and the cool looks even cooler. But, for instance, in the shadows, we can have lots of different cool colors, and we've got an interesting shadow. It still remains a shadow. Because we haven't put any warm colors in there. All those colors are cool in relation to each other. Things like purple and blue and a dark green, for instance, put those all together, even a slightly warmed up purple. It's still going to look cool. It's still going to fit in to the shadow. Now, in the lights, we can have lots of different warm colors, yellows and maybe sort of peach colors and orange soft oranges, colors, reds, all of those, they're all very similar in value. That is, they're all quite light in value, but they have different warmths, right? One is a little warmer next to the other and so on. That's how the impressions created a sort of vibration in those colors. Now, with our dune, we've got the hot sand, we've got the cool shadow of the dune. So cool against warm, that's going to create an immediate and eye catching contrast. Not just light and dark, but warm and cool. We're going to use those temperatures. Then we've got the sea in the background. We're going to create a bit of sparkle on that sea. And once again, it's going to be a comparison of warm and cool, but also the value contrasts, the light sparkle and the sort of deeper darker color of the sea. That's going to create a sparkle, and we're going to just play around with that and create that bit of a zing to. Finally, thick and thin. That's also a contrast, isn't it? In our lights, we're going to use thicker paint. You maybe even want to put paint on with a painting knife and get it really thick or just a lot of paint on the brush. In the shadows, more transparent and thinner paint. Not so much white paint in it, almost none, actually, and it's going to be thinner. So we're going to have that thick contrast in the lights with thim cools in the shadow. That's also a visual element that attracts the viewer and gives us something else to look at. So those three concepts, I'm going to weave into this painting, and it's going to make all the difference. Alright. So with those ideas in place and the materials, let's have a look at the reference and start painting. 4. First Steps: Compose &Tone: Okay, our reference is quite straightforward. I'm going to tone my painting panel, and I'll discuss that as well. And then get into the painting itself. It's not going to take a long time. It's not a complex painting, but it's all about creating a light effect. And that I think is something that can transform your painting and make them really pop and stand out when you try it for yourself. But, let's start off by getting a paint on the palette. I like to start off with the titanium white, then add the cool and warm yellow. Then the cool and warm blues. And then the raids, as well, the red light, and the quinacridone aid being the cool, then yellow ochre and burn sienna. Get the water, and I'm ready to start drawing out a simple composition. Quite straightforward because it's not a complicated reference, but get a basic composition down. I'm going to make the see just a little bigger because I want to play around with some nice sparkling light on that see. I'm going to leave out the peer at the top right there. It's not really going to add much to this scene, so I'm going to leave that out. And now just start with a light toning of the panel, not one color, but more or less block in in a toning sort of fashion, if that makes any sense. Sort of kind of the under painting of where I want to paint the sky and the sea and the beach and so on. And sometimes I will do a toning color in an opposite color. So I'll use some worms in the dune and then paint over that with the cools. And there may be a little glimpse of some of that warm paint showing through here or there. You never know. It might do that, in which case there's an extra little buzz happening there, just a little point of interest, perhaps. But for the most part, I just like to start off with a color that's down, and it gives me a bit of just a little confidence boost, I guess you could say, but it might also help with the painting. So this I will let dry and then start with the main painting once it's all dried up. 5. Dune Painting: But while that initial toning is drying, I clean off the palette. This just helps to make sure that my color notes remain clean and don't get muddy. Quite a problem with the acrylics, the muddying up of color notes happens very easily. Right. So let's start with the darkest dark. It's sort of a traditional approach with any opaque medium, start with the darks and it's just a basic and this will be the underpainting for the dune, the shadow of the dune. I'm going to add a bit of cerulean and a touch of that quinacridone red or your zarin, whatever cool red you use. I've added a bit of white, but just to lend a little more opacity to the paint. But in comparison to the colors itself, the white is kept to a minimum and just dragging the brush at the end here where I envisage the shadow to break up a bit, a little bit darker in this foreground corner. And then the shadows, it might be more imagined than real, but I try to lighten them a little at the end of the shadows and on the edges. And that's done with dragging the brush and also just lightening the paint a little. So now using the burnt sienna to darken the area where I'm going to be putting dune grasses, and that just helps to create some shadows and putting a few dabs of that in the dune, as well, because there are organic things scattered across the beach as well, could be twigs or even just footprints, but there are marks in the sand. Now, the sea, I'm going to paint a dark greenish blue. I'm doing my own thing with this S. I'm not really copying the sea as it is in the reference. There's a reason for that because I want to create a particular sparkle to this sea, a technique that you can use in any situation where there's water. It could be a lake or even puddles in the road, for instance. We'll see how that works out. And now let's get some color in the sky, titanium white, touch of lemon yellow, and just dragging that brush more or less straight across the horizon. Now, I don't really worry too much about horizon lines. As you can see, I had a little bit more blue coming in for the top there. With the horizon line on a seascape, I like to blur that horizon a little. And you'll notice as I go along, I will sort of drag the brush and not make it a perfect razor sharp edge. It's just too, eye catching. And for the most part, there's some sort of atmospheric effect which should soften up a horizon on the sea. Now just softening that color up just a little touch of cerulean, little touch of white, but very small amount of white. And that just sets up things for some nice light color. Let's get a bit of space back on the palette because I'm going to venture into some new colors, some of the lights as well as the dune grasses, the sort of brownish orange and yellows and ochres, Stall an underlayer. Harmonizing that color a little by throwing some into the dune itself because there is a bit of that grass in the shadows. Well, most of the grass, in fact, is in the shadows, but I'm going to make a little more out of it, bring a bit of light into that grass, as well. And now for the beach, it's basically titanium white, yellow ochre, and some yellow to warm it up more. I love this part, adding these bright light colors, how that intense light is accentuated against the cool darks of the dune and even the sea. Touch of red light, little bit of blue, and just to sort of get a wet sand effect. So it's a bit of a violet color or a coolish pink so that is a very rapid blocking in. But now you can see how these big shapes are so important. I'm going to bring some variety into this dew now. I'm not going to leave it a flat dark color. Watch how I drag this brush on the edges, just to add a little bit of blurred edges and a slight atmospheric look to it. The dunes shouldn't look like they've been pasted on like a flat two dimensional surface, either. So there is light sort of filtering into shadows, right? Indirect light bounced off the sky and on the sand in the distance. Otherwise, the dunes would appear to be as if it is nighttime. That's not the case. So I bring in a little bit of white, a little bit of yellow ochre, but not enough to create a light dune, right? It's got to remain a shadow. It's got to be a shadow value. We're not going to worry too much about the value scales and things like that at this stage. But if there's no direct light on it, it's a shadow, and it must not be mistaken for anything else. However, I don't want my shadows to be flat, dark, lifeless things. Either, there is hints of things in there. Now with the deep yellow touch of red, some white, I can bring in the foundation for the dune grass. Notice I'm using the large short flat brush to put these shapes in. So even though you're putting in something like dune grass, doesn't mean you must use a tiny brush. For the initial layer. Now I'm got the rigor to break things up a little with a bit of lemon yellow and some white, a little deep yellow and white. And we're just going to drag the brush around and create a little bit of texture. Try not to overdo it. You don't want 1,000 tiny brushtrokes. We're suggesting the grass. Break some what I call sky holes into the shadow at this stage near the end of the shadow as well to create sparks. I like to call them sparks. There are, of course, highlights, but if highlights are done well, it looks like you got these little sparks of light. And I'm adding dark accents suggestive of perhaps footprints or pieces of wood on the beach or stones, even just to add some point of interest without describing it in any great detail. Basically, breaking up a flat surface. Let's get a little more temperature variety within the lights a little touch of burned CNA and white, a little bit of red and white. It's still a bright sunlit area, but there's little variations of colour temperature. And that just makes the surface more interesting. Topping up the white and there's the wet sand back there. It's kind of a bluish violet, or it could be pink as well. What's the color of wet sand? I've done videos on that on YouTube as well because it's always a bit of a head scratcher of what do you make wet sand color out of? And for me, it's usually a pinkish violet perhaps. And I just think of cool water on warm sand, and I get that sort of violet image in the mind. Breaking things up on the water's edge a little before I get into the sparks of light. So this I am moving in my own sort of direction here. And all I want is an interesting pattern on the sea. Where there's intense light. Basically, I'm putting down impasto strokes. A lot of titanium white, bit of yellow, quite a lot of paint on the brush, and I'm going to put these sort of angular shapes, dots and dashes to create a multi varied surface that looks like sparkling water. You go to stand back. You got to have a look. Is the illusion coming across? Maybe you've got to reestablish some of the dark colors of the sea again. In which case, that's what I will do. But first one, just get these strong lights down. Get a bit more blue, softer blue in the foreground, where it's shallower. But also I need some dark blues, dark blue greens to react against those lights. Let the see colors just settle a little and create a suggestion of clouds across the sky. Break up the light of the sand again, and then some impasto strokes to suggest the foaming water coming onto the beach. Let's get a little bit of color on these edges of the dunes. And here, I'm using a slightly more lighter violet color. I want the foreground of the dune to remain quite dark, and then I'm just adjusting that value in the middle part of the dune. Touch light there. Let's just make that slightly darker. So this is creating some more visual interest in the dune, but be very careful about making it too light. Just keep it a strong shadow. Okay, so, assess the painting. Let's get some of the intense highlights, the real sparks in that grass. Once those first yellows have settled down and dried a bit, I can go over it with the lights, putting a few of those little dots and dashes in the water as well. Reestablishing some of the lights in the foreground of the dune. All of these little sparks bring things to life, but you got to know when to stop, as well. I always tend to put a few too many. But if I see that there are too many, I'll get rid of them. Marks on the beach help to break up the surface and also suggest a few bits and pieces. And now I'm going to add a figure very loosely done a figure to add a bit of scale and dimension and a point of interest. I'm just using it's basically made up of rectangles with a round shape or oval shape for the head. Make sure the head is small, one leg longer than the other, because he's walking and a shadow to attach the figure to the beach. Alright, I want some stronger darks back here to add a bit more value contrast and get a bit more of that sparkle in the sea. Kind of abstract, isn't it? But I think it does work. It's almost a contemporary approach. And just assess whether you need to add any more highlights or impasto highlights. Okay, I'm going to sign this off using some of the cool red That one's just a bit too dark. Just soften that up a bit. And we're pretty much done. And I've enjoyed the painting. I think we've made the scene a bit more interesting. So I hope you enjoy trying this out for yourself. 6. Conclusion: Well, there it is. I really enjoyed that painting. And, you know, even though it's a relatively simple idea and subject, a light filled painting like this brings me a lot of pleasure, and it's so much fun. You don't have to get bogged down in complex things. A painting can be powerful and simple, and of course, you're going to enjoy it so much more. So download the reference, try the painting out and share your results. I hope you have fun with it.
