Hit the jump for my theory on why we like blue... (and for more blue pix)
Ok, so if you think back to basic junior high biology, you'll remember the eye sees light with rods and cones at the back of the eyeball. Rods are good with black and white as well as low light vision. Cones fill in the colour.

We have way more red-receptive cones than blue-receptive. However, our rods are able to pick up on blue in low light but are not stimulated by red. This means that in low light, red is less 'distracting' because it uses the cones whereas other dark viewing areas will be using rods. That is why vehicle dashboards are often back lit with red; it won't kill your night vision while driving in the dark.

However, in brightly lit environments, red will tire out our eyes because it's using more cones. Blue uses less cones and some scientists speculate that our brain boosts blue hues. My theory* is that humans feel that they like the colour blue because it is physically easy on the eyes, plus is stimulates the brain. How cool is that!?!

Even if that's not the reason we like blue, it is fascinating that our body is physically stimulated differently depending on the wavelength of light entering our eyeballs and hitting our retinas. We know this from research into colour therapy and marketing.
Here is an article from Georgia State University that explains rods and cones in greater detail.
