what is the difference between that and what pigment does?
The design or setup makes one purple the other is purple.

It’s actually surprisingly common. For instance, butterflies and peacocks also use this: https://en.wikipedia.org/wiki/Structural_coloration (In fact, I’m pretty sure I read somewhere that only a handful of blue pigments exist in nature; the vast majority of blue animals and plants use structural colouration instead. Can’t recall where I saw it, though.)
I find the blue sky one of these common yet amazingly beautiful phenomena.

Something can be both common and amazing ? I find the blue sky one of these common yet amazingly beautiful phenomena.
