For a fool proof color scheme I tend to pick monochromatic palettes with white or black for contrast. I forgot to photograph the gold but I also use gold or silver for a pop of color with these basic palettes.
Here is my final painting dried and ready to get a protective spray finish put on.
This is a close up showing the small natural cells that showed up in my painting. You can also see how some of the gold is hiding just below a thin layer of white paint.
