Seems to me that Shimano 600 tri-color components have a pretty loyal following here on bike forums. I know I have been partial to tri-color since about the time it was introduced.
I really like how tri-color stuff works, it looks good with the highly polished hubs and the gray paint/anodizing on the brakes and rear mech. To me, it is very close to Dura Ace from a functional perspective but not quite as light and not nearly as fussy as DA. My two road bikes have a combination of 7700/7800 DA and tri-color bits. All of my hand-built wheels have the 600 tri-color hubs. They perform especially well going downhill as they spin really fast. There is something about the seal design that keeps crud out, but adds very minimal drag.
Let's hear it from the other tri-color fans on BF.

I like my Tricolor too

My first real bike way back in 1982 was a Panasonic with Shimano 600ex. Great bike that logged tens of thousands of miles. Several years ago I found a bike with Tricolor 7 speed. It has become one of my favorite bikes. I can certainly understand why people think so highly of 600. I also have a dura ace 7700 bike. Dura ace is wonderful but it can be finicky sometimes, bottom bracket, freehub, front mech. In my opinion TC has all of positives of DA without the nit picky negatives.

I definitely think it's cultish to call Shimano 600 Ultegra parts "Tri-color."

I love the flexibility of the tricolor series. 8 speed, 7 speed, brifters, DT shifters. Single pivot brakes, dual pivot brakes. Aero brake levers or non aero brake levers. They can all be found in the 6400 series. And unlike the 7410 series, the 6400 is compatible with other Shimano groupsets too.
Recently though I did something heretical- I paired Claris R2000 brifters with a 600 tricolor groupset. I figure the Claris brifters being grey in color, would match the grey 600 series. But as it turns out, the Claris is quite a bit darker:




On the bike they look almost black unfortunately:

Cool bike - when I mentioned this fact to a Dura-Ace adherent in another fan thread he replied that they look at that as a feature not a bug...

Sometimes I think that Dura Ace would be more fitting with the quality of this frame. Then I take it for a ride only to realize that the tricolor is simply excellent. The dark gray finish goes wonderfully with this color way. Certainly a fan!
