I always try to purchase my set-ups in Red/Blue. I am a traditionalist. That being said, I have the Dal Negro Torcello Blancos, and my Kems (pre-USPC) are Green.Black (Foxwoods), and Green/Brown (CaraGails). I do have a set-up of Copag 1546 in Burgundy/Green too. But yeah, since getting the "bug" everything has been Red/Blue where possible.
And yes, everybody does use that combo, so I look upon it as making comparisons easier. With the exception of my Desjgns, all the Red/Blues are close enough to make differences negligible. At least, to my aging eyes.
You've seen my chip colors that I roll with in my Chip Sets.......I'm obviously not a "traditionalist", lol...........I like mixing it up out side the...............................as well
