Color Palette Composer

Has two inputs:
- 1 color ( or more colors via color-ramp or checkers-node).
- A slider to adjust the distance of the adjacent colors of the color-wheel. A value of around 10 gives nice adjacent colors. Around 120 it gives more like triad colors. Just play with this slider until you like the result.

Output:
Makes a render of a color palette depending on the input color.
I used the emission shader, so rendering is quickly and the colors are accurate.
- It shows the base color ( the input itself ). And a highlight of it in the middle and a darker shader of it on the outside.
- It shows the opposite color with its highlight and shadows.
- It shows the adjacent colors with their highlights and shadows.
- The middle circle shows the highlights.
- The ring shows the original colors
- The outher part shows the shadows.

Don't hesitate to give some suggestions, and improvements are welcome.
( Especially how to make the slider function not only artist friendly, but also "physically correct").

Don't mind about the License, Use it for whatever you want.
