Does square enix hate purple?

[TeraRamis]

Literally every color on the screen you're looking at now is made by mixing red, green, and blue. If you look at a color wheel, the majority are shades of red, green, and blue. The human eye prefers red, green, and blue. How many shades of purple do you think there are and how many do we need? And why did you pick purple out of the list of colors and not yellow?

Red, yellow and blue. Green is not a primary color.
