The primary colors are? Warm colors are? Cold colors are?

Answer 1

Hi and welcome to QuestionCove!
When we're talking about pigments, the primary colors are cyan, magenta, and yellow. Or, blue, red, and yellow, more generally.
When dealing with light, the primary colors would be red, green, and blue.
It's kind of hard to explain what warm and cold colors are, but if you've ever seen a color wheel, warm colors are mainly on the red side, while cold colors are more towards the blue side.
