I'm not a big fan of just flat black. I like a deep grey, gunmetal grey or carbon with a visual texture.
My roadbike's nude carbon black... with the weave pattern of course.
I also want to show off my newly built black homemade repair stand that I constructed for under $40.
My MTB is mostly nude carbon black with a weave and multigrain finish.
I also don't like components that are totally black. For instance, the cranks on my MTB while annodised black have a slight purple tint to them. The XTR groupset is that matte gunmetal grey. The chainrings on my RB have a similar colour. I see that Campagnolo is releasing Centaur in a polished gunmetal colour. I think I'd prefer that finish over polished silver. Of course I'd prefer the carbon finish of Record over all.
