Women have much finer color recognition. I work with color copiers and similar equipment. If you are a technician and are having trouble getting the color balance on a machine just right do not ask a woman to look at a test copy. You will be there all day.
Yup. And more men are “color-blind” (even if it’s only 2-toned).
A woman is expected to know 27 shades of white, and be able to distinguish the differences between red, scarlet, crimson, vermilion, blush, ruby, carmine, cherry, etc., etc., without a reference sample...
