Not to be mean, but I think every assertion in your comment is wrong. Blue and Green are English words which sometimes describe primary or secondary colors additive colors. Cyan is (an English word that describes) a primary subtractive color. Colors are not English words. They're physical reactions inside our eye-brain systems, affected by varying wavelengths of light. (Actually that's not the most accurate description of color either, but it's a more useful model.)
