Rainbow coloring

In graph theory, a path in an edge-colored graph is said to be rainbow if no color repeats on it. A graph is said to be rainbow-connected (or rainbow colored) if there is a rainbow path between each pair of its vertices. If there is a rainbow shortest path between each pair of vertices, the graph is said to be strongly rainbow-connected (or strongly rainbow colored). (Wikipedia).

SmoothLife 3D rainbow 1

There are people on the world who know me and what I draw or paint on paper, who fully expect this stuff to be rainbow colored. This is my first try at this, but it's still wrong. The colors have to be all over of course and changing. I will have to look into 3D texture gradient or somethi

How Are Rainbows Formed?

This video explains how are rainbows formed, why are the colors of the rainbow in such an order and under what conditions are they formed. Rainbows are meteorological phenomena caused by few optical processes. We explain these phenomena by showing what happens on a single raindrop and how

AMAZING RAINBOWS FROM CD SURFACE (EXPLAINED)!!!

The white light from sun reflects on the surface of the cd and, due to diffraction (at the cd diffraction grating), the light spreads and interference to the wall. Each color of white light has a different wavelength for this and is analyzed in the colors the rainbow.

Can You Reach The End Of A Rainbow?

The end of the rainbow may be the best place to raid a leprechaun stash, but it proves a strangely difficult destination to reach. Brainstuff explains why you can’t get there, and why there really isn’t even a a “there” there. Learn more at HowStuffWorks.com: http://science.howstuffworks.
