True, black is always a good go-to. For me there are a lot of good options depending on which generation. I'd vote for anthracite or cool steel (or lavender steel) on the 3rd gens. 4th gens look great in black or nautical blue. 5th gens look best in salsa red, in my opinion. Inferno and cavalry blue are awesome on the newest TRD Pros, but I don't think I've seen them in the wild.
