Hash me about LEDs.
Couple things real quick. The Giant Blue Morpho, aka morpho didius is a large blue butterfly whose wings exhibit a property called iridescence. The color of the wings shifts with the viewers perspective, curiously though the actual color of the butterfly wing has nothing to do with what it looks like. This is an area of science called biomimicry - copying life verses reinventing the wheel. The wings color shifts because it is covered in millions of microscopic scales or tiles... almost like overlapping shingles on a roof. The length of these scales are in the nanometer range, just like visible light.
Just like visible light. So if you want a panel that only reflects visible light, cover it with millions of tiny iridescent scales at peak PAR nanometer wavelengths and it will reflect only that light, absorbing all others.

We've already adopted this tech into digital displays. Only a matter of time before I or someone else adapts it for passive light distrobution. If you beat me to it, well played, but you gotta buy me dinner once!
