Speaking as a guy, not always true. I've lost some of the skill, but there was a time when I worked with paints mixing colors, and I was very good at finding the right shades for people who were lost (men and women). I understand that there are subtleties within every color.

My sarcasm would always come out though, when someone would bring in a piece of wood and ask to color match it. I'd ask "which brown"... but then would give them excellent service and figure out what worked for them. Hated and enjoyed that job.
