I have no stats to back this up but I too believe blue hues are extremely rare in nature compared to red, yellow, and green. Someone below cited fruits (which I can think of one that is blue), people eyes (one species, and usually only a tiny subset of that species), and some flowers. Other than that, truly, what other common natural blue do you see excluding water and sky?

"Blue" is as common in life as any other "colour" - your eyes are just less sensitive to it because there's so damn much of it on earth. If you "de colour corrected" the human eye and brain, you'd see everything outdoors as a deep blue.

  I don’t think that matters here. What matters here is our perception and only our perception, since this whole discussion is only about perception and what humans do with that perception, not wavelengths.

What about purple? As a side effect of a meditation technique I use, I several times daily look for one each of objects in my environment that are red, orange, yellow, green, blue and violet. Blue takes a long time to find and purple takes longer. If sci-fi screens are blue bc of rarity, wouldn't purple be a choice, too? I think blue and purple are strange and rare. But purple probably has too many connotations with little kids' arts and crafts or quirky old people. And we don't have to limit ourselves to what is natural, we can consider things in the man-made environment. We tend to make many more things blue than we do purple. Looking around my desk: Blue things: static mat, phone LED, supply label, USB cable, sticky notes, Outlook, mouse pad, pen, bananajack, map, medicine bottle cap. Purple things: coffee mill box, cover of notebook.
