6x6 Proud Python

This extends the 4x4 Quad Color Python concept to six colors on a 6x6 cube.

6x6 Cube in Cube in Cube in Cube in Cube in Cube

This is a straightforward expansion on the common Cube-in-Cube pattern. I tried to arrange the colors carefully so the same colors wouldn't touch each other at the edges, since this tended to make the pattern look like a broken spiral. Every side has all six colors.
