Old article but very much relates to topic. These could be really sweet or really bad. I like giving them a shot though
The best and worst of college basketball
With 2 of those, Ohio State and Georgetown, gray is the secondary school color. GU has had the gray-based unis for years. KSU has only one "official" color, but has adopted gray/silver as secondary, so it fits.
Texas looks fine with gray, but schools with non-white secondary (Wichita State, Purdue) there's already an alternate option.
Gray works well with most colors — it doesn't get in the way. One of my Iowa State T-shirts has the gray background. If ISU did gray, it'd look fine. I just don't think it's necessary to stray outside the school colors.
General note, I apologize for my previous "end-thread" comment — I was in a bad mood.
