The Rgb color space consists of all possible colors that can be made by the combination of red, green, and blue light. It's a popular model in photography, television, and computer graphics.
Cmy is frequenty associated with color printing, and it's determined by the relation of colors cyan, magenta and yellow. Unlike Rgb, cmy is subtractive, meaning that higher values are associated with darker colors rather than light.
