My first mtn bike was neon yellow with black splatters, it was appalling. The second is dark blue and I found I missed my squinty-eye bike. I made up for it with the third, a bright easter egg green. My road bike is white (bleh) and my tandem black/silver/grey (super-bleh). I don't regret any of them because they had what I needed at a price I could deal with.
But that's just me.
