Sky Colours on Desktop - Opalite glass photos
Opalite is an interesting material, that produces significant Rayleigh scattering on cm-scale. This effect is responsible for the main colours of the sky.

Diffuse lights of everyday lighting conditions blurs this effect, but in a dark room a spotlight can reveal the amazing colours of blue sky, orange and red sunsets.
