Thanks for the new version.

Alright I have a question:

How would use those colors as masks for shaders or geo placements?  I still haven't figured out how to restrict a shader to a specific color. 

Thanks

The hue (0..1) is seperated in 6 ranges. Each range contains a primary colour and a secondary colour.
The primary colour is constant, the secondar colour is either increasing or decreasing.
E.g the range from hue=0 to hue = 1/6, the Red is constant and green is incresing giving a band of colours from red to yellow.

To extract a range use  multiply two hard step nodes with the two constants and the hue as inputs.

You can do a similar thing with an x to scalar, a rotate, add, and (quite) extreme warp.
