Why blue? Well there's a reason Facebook chose to have a theme/style which users cannot override like on MySpace, and made it blue. Blue is the base color for design and fashion - color of sky and sea, jeans and first suit. Perhaps they were also hoping to boost sales in a recession, knowing that males don't spend much on "spring" fashions of pastel colors. Or they picked up on the basic vibe of Americans, going back to what is conservative and tried, "true blue," during tough times of uncertainty and hardship.
Spring 2 inventory brought the whole spectrum back into view, but it was interesting for a time to have one color at every store in the mall. Having a bank job supporting an insurance client, I've been big on blue this year; and it has ever been my favorite color.
