I don't want to have to join a Colorado ( or ISU) board to ask this. I had an odd memory come to me while bicycling this afternoon. Only thing that could be odder is if the memory didn't even happen.
I grew up in Des Moines in the 60s and 70s. For basketball on Saturday afternoons, channel 13 showed the MVC game of the week, 8 had the Big 10, and of course 5 had the Big 8. We didn't get a color TV until March 1969.*
So, with regard to Colorado, we would be starting with the 69-70 season ( the Cliff Meely era). What I remember, though, is that every single game broadcast EXCEPT for the ones played in Boulder was in color.** Colorado home games were black and white. Altitude? I also remember the Colorado floor having some weird gloss, so maybe didn't broadcast well in color. Anyone else remember this or able to explain? I suppose I'll manage if I don't get an answer.
*It was in fact the very night Drake played UCLA in the Final Four. My recollection has always been that this was a coincidence, but that sure sounds naive when read.
**The basement TV was still B&W until the 80s or so and where I spent much of my time.
