Working from memory.
MU was always green and white. The specific shade of green was always described as "Kelly" and this generally meant "lighter than average" more than a specific shade.
During the Sonny Randle era, they added in a lot of yellow. Part of this was a mimic WVU thing (WVU has just switched from gold to yellow, never to return) part of it was to distinguish from OU, part of it was just "most schools have two colors plus white, why do we have just one?". The yellow found its way into basketball and the band, but some other sports resisted. I don't think baseball ever had any yellow.
Then came Parrish. A condition he set when he took the job was a complete set of game uniforms for the whole team. Which were Penn State/Alabama plain because that was all we could afford. Green and white, plain. THAT is how broke we were (also when the stadium was half torn down, turf was rotten, etc. ) Which is when we were closest to shutting her down, not 1971, which I why I lose patience with those who cannot be happy with the 100000 times higher place we are not, but I digress.
Then came Chaump. He was an OSU guy and changed everything to green and gray. Just football, everyone else ignored him.
After that is when they really settled on the actual color "Kelly" and they had some committee that had to do with "branding" university wide, got rid of the yellow map of WV between an MU logo, and a lot of other logos, including one of an Old Main tower that supposedly looked like something out of D&D, and a lot of stuff. The colors of the glory days were Kelly green and white.
Then came KO, Satan's vile servant. He went with the Michigan State dark green, some say out of incompetence, some say it was a choice. When called on it, he lied (one of thousands of lies he told) and blamed Nike. Someone on this very board posted a link to North Texas' (then not in CUSA) Nike uniforms and showed him up.
Then came the current era.
