What would you say is the “official” color of corporate or collegiate environments?

A lot of schools in this area other then the high school have switch to some form of uniform. When I am out of the office and in Starbucks availing myself of their WiFi, I see them file in on the way to class. Then there are those you know work in corporate casual offices (the dangling name badge on a lanyard is kinda a giveaway) why pass through as well. There seem to be a definite favorite on colors; maroon, navy, khaki, with black, white, and Hunter green close in the rear. You see the combinations navy top khaki bottoms; maroon top black bottoms; maroon top, navy bottoms; khaki top, black bottoms, etc. You never see pink, purples, fuchsias, reds, etc. There are definite favorites but is there a combination that is the “official” color of corporate (casual) and collegiate?
