RADIAL Colorramp gradient texture Ok so I got as far as getting the colors I want, and making them gradient. Now my question is how do I get the colors to wrap around a circle mesh like the rings around a planet? Im guessing it has something to do with mapping?
In cycles
use a gradient texture using a quadratic sphere as the color style blending.

Blender Internal
Use quadratic sphere for the blend and sphere for the projection:
