in the reading of additive or subtractive i learned about making colors by adding or subtracting primary colors. The primary colors are red, green, and blue. Those primaries are used in the additive method while magenta, cyan and yellow are the primaries in the subtractive method. Green and red added make yellow. Red and Blue added make magenta. Blue and Green added make cyan. This is all figured out by looking at the color wheel. where yellow and cyan overlap, they pass green. Where cyan and magenta overlap they pass blue. Where magenta and yellow overlap they pass red. This is also seen on the color wheel.
