TCU is the home team and dictates the uniform scheme. Not Dion or Colorado.

James Franklin—
"First of all, part of the White Out is the contrast. It helps us if everybody else is in white, it makes our players stand out on the field for our quarterback and those types of things. That’s the first thing. The other thing is, we can’t wear white at home. There’s NCAA rules. We can’t show up and wear whatever we want to wear. We would have to get permission from the opposing team to allow us wear white, and I would never do that for anybody else, so we haven’t even kind of gone that route.”
Franklin did a great job explaining the rules, but in case you wanted to see it in full, here's what the NCAA says,
per a uniform FAQ memo from 2018:
9. What are the rules about jersey colors for opposing teams?
By rule the visiting team must wear white jerseys. This means white, which does not include light gray, pale yellow, etc. The home team may wear white, but only if they get written agreement with the visiting team before the season starts (Rule 1-4-5-b).
10. Is it possible for the visiting team to wear their home (colored) jerseys?
This is possible, under these conditions (Rule 1-4-5-b):
- The home team must agree in writing before the game.
- The home team’s conference must certify that the color of the visiting team’s jersey is in contrast with that of the home team.
- If the visiting team wears colored jerseys without meeting these conditions, it is assessed a 15-yard penalty before the first play from scrimmage after the opening kickoff in each half.
