Well, I don't think its cool because usually cool color schemes involve a lot of blues,purple, black, etc. These colors help create a 'cool, quiet, or even lonely atmosphere So, it is not cool. A warm color scheme, just like cool, uses it own main colors that in a way match the word. Some warm colors are warm orange, golden yellow, and lime green help create a 'warm' and lively background. Complementary color scheme are colors that are opposite of each other on the color wheel are considered complementary colors. (an example: red and Green/ usually the color wheel shows what the opposite of a color would be.) The high contrast of complementary colors creates a vibrant look. As for secondary colors, or secondary color scheme, are colors/scheme you would use to paint a realistic painting. These colors can be mixed with others to get the perfect, or similar, color needed for the painting. So, the answer for this painting should be Secondary. I hope this helps and sorry if I'm wrong!! XD
