I find silver, black and occasionally red are quite dull colour choices. Granted there are some components out there in more interesting colours, but the engineer in me won't let me choose the "wrong" component simply because it looks pretty.
So I'm wondering what the options are for colouring metallic components, chainring bolts, brake levers, etc, at home. I suspect painting wouldn't look quite right and in the case of bolts, might cause things to get stuck or flake off in use.
How about anodysing? Is it something that can be done safely at home without too much risk of ruining the component? Does anyone have experience of this?
