I match my helmets to my bike. I think most people here do it that way. I wear lots of black and blue, and some yellow and pink. My bikes are red/silver/pewter and black/silver, so it would be kinda hard to make *everything* match.

I have three helmets, which are silver (Bell Sweep XC), black/pewter (Giro Atmos) and silver (Giro Atmos). I use the first two, and have the third one on reserve. Normally I would have waited until I really needed the third one, but the silver Atmos is a discontinued color, so I snatched it up when I found it. :P

I do think that it's a good idea to have a spare helmet, even if it's an older one, as long as it's still in usable condition.
