I've always heard that blue paint (such as on vehicles) tends to fade sooner than other colors.. Looked all over this site- http://www.cis.rit.edu/fairchild/Why...r/shortAs.html -to find something about color fading, but didn't see anything about blue specifically.. It did mention that the colorants used in some dyes and fabrics affect the fade-ability (I dont think that's a word, but hey- it works) of paint, clothing, etc... so... stick to black!
