I recently noticed a lot (maybe half) of my icons are blue, or in a faint shade of blue.
It's also true for the favicons in my browser bookmarks.
The new Windows 10 default wallpaper is blue, and the default color is blue. Even Stack Exchange uses a lot of blue (for text), and UX Stack Exchange main color is blue.
So, what's up with this color? Is there some kind of explanation to why it is used so often?
I remember that human eyes are more receptive to green, so that seems weird to me.
