I have recounted here before that when I first went to Carnoustie, the tees were orange, green and yellow. Each of them used six regular tees, six forward tees, and six of the Open Championship tees. So, the day I first played it, I played #16 from 248 yards, then on #17 we were forward and could actually carry the far crossing of the burn, and then #18 we played from the normal men's tee.
It was very cool, and since there were no long carries over waist-high grass, you could play a few holes from the Open tees and actually finish them. You didn't expect to make par on those holes, but if you did it was a real thrill !
From 1973 - 2001, Brae Burn CC in Purchase, NY employed a "3 Color" system (imported from Fresh Meadow) of Blue, White and Yellow which saw 6 holes where each color was forward, 6 where each was middle, 6 where it was back, whereby each tee resulted in an aggregate yardage of around 6350. A pennant would be flown by the putting green, indicating the "color" of that day... Each "color" course had its notorious virtues and vices and challenges and opportunities
It also had the further utility of having members decide to play their casual rounds from any "all back" "all middle" "all forward" set or combinations thereof (usually back tees on 3s/5s and middle on 4s).
Lastly, this approach worked seamlessly with the utilitarian ethos of an RTJ-inspired/Frank Duane-designed course which features large teeing grounds and large segmented greens, which already bolstered the course to play differently each day.
