SRAM made derailers and shifters in a lot of different colors back in the 9 speed days. They were XO level and came in red, blue, gold, green, and pink. There may have been others but those are what I’ve seen. I own a red and green one as well as the matching shifters. I’ve repurposed the shift levers to match my Dean’s color scheme of red, blue, yellow and green. This is repeated throughout my bike.
