Here’s one thing that has always bothered me: Why don’t the Cowboys play in their dark blue uniforms at home? I hardly see them in their blue uniforms, only the white ones.

Too harking hot in Tx to wear dark blue.

I believe the tradition is "light" for home, and "dark" for away in sports.

My theory is that it was easier to clean the light at "home", not so easy to keep clean "on the road", hence the darker variant.

Probably started with baseball way back.

Wikipedia (which is always right because it's on the Internet) says: "Until 1964 Dallas had worn blue at home, but the use of white jerseys was instigated by owner Tex Schramm, who wanted fans to see a variety of opponents' colors at home games." and cites ESPN: The Island of Misfit Unis

It's easier than holding up a white flag.
