Apple Loves Blue???

UntitledSometimes I can’t help but notice how much blue Apple tends to use in their icons. Both OSX and iOS.

I wonder if it’s b/c they have a preference for that color for some reason or if it’s more for flow and appearance???

Some other icons are designs (maps) or another color (iTunesConnect) and such, but there’s a lot of blue in there too.

The group of icons in the pic are things I normally have up… well, I don’t always have iTunes and the App Store open, but the rest are completely legit. Others?
