What NCAA 4 schools that are colors?

There are several NCAA schools whose primary colors could be considered colors themselves. Here are four, keeping in mind that "color" can be subjective and school colors often have variations:

1. Purdue Boilermakers: Their main color is Gold.

2. Oregon State Beavers: Their main color is Orange.

3. Auburn Tigers: Their main color is Orange (though often a deeper, more burnt orange).

4. Maroon: While many schools use maroon as an *accent* color, the University of Massachusetts Minutemen and Western Michigan Broncos are among those that feature maroon prominently, though often alongside other colors.

It's important to note that this is subjective; other schools could reasonably be included depending on how strictly you define "a color" as a primary school color.
