VantaBlue   (+3, -1)  [vote for, against]
Like VantaBlack except it's blue

Nanoscale textured surface except instead of being carbon nanotube "whiskers" (black) the "whiskers" are lazurite crystals (blue).

We need a VANTA Black Man Group.

Why blue, not red?

Because you don't want to be hurled to your doom from the Bridge of Death, presumably...

That's an expensive Fanta. Mixgeology.

[+] 'cuz the name's cute, but horrible science : if you had a "vanta" nano-structure, it'd be black, that's what it does.

Could plasmonics make a bluer blue than diffraction, or a blue photovoltaic power minute LEDS or lasers

^ Intricately complex structure that converts all* forms of energy to a specific band of blue? The needed blue. Some out of solar system minerals may be a requirement.

Due to the inherent inefficiencies of photovoltaics, an absorptive - re-emissive system is always going to be less efficient than simple reflection of desired wavelengths.

Reflecting only desired wavelengths, but also absorbing all other undesired incident energy and re-emitting on that desired wavelength will indeed produce a "brighter" colour.
