When putting this pallette together I used colors I liked and used most often. I wanted a warm and cool of each color if I had it and used it. This was a meedan 12 half pan tin pallette and it came with extra half pans so I was able to fit 14 colors. I might be able to add more half pans in the center if I turn the pans horizontal.
My second self made palette was some newer paint s I bought so put this together. Also a Meedan 12 half pan tin palette. this time Amazon had it in a pretty color print. Also came with extra half pans.
I swatched all my paints organizing them by brand of paint on a card and put it on a ring. On the back of each card I wrote the brand/company.
