I see all those accessories as, well, accessories. Mine are all black and I really could care less. I was perfectly happy with my black handlebar tape until DH decided to put red tape on my bike, so it matches the frame.
I also have never even considered the color of my bike... I've had 3 road bikes, one yellow, one Trek utilitarian carbon colored, and the one I have now which is red and black. It was whatever color fit me and had the components I wanted. I suppose if I had some kind of really negative reaction to the color of the bike, I might have thought about it, but I've never seen any of this as an option to "think" about.
