response: It is a mixture of yellow and blue in subtractive color systems though.
history: green is a cool color. Ah, OK. It's between yellow and blue on the visible light spectrum. Yea mixing those two gives green so it makes sense
knowledge: In subtractive color systems, used in painting and color printing, it is created by a combination of yellow and blue, or yellow and cyan; in the RGB color model, used on television and computer screens, it is one of the additive primary colors, along with red and blue, which are mixed in different combinations to create all other colors.
