Select colors on a 3D sphere

# Colorsphere - An RGB color picker with colors arranged in a 3D sphere.

This module implements an interactive 3-dimensional color picker - to the author’s knowledge the first ever 3-dimensional color picker.

The color sphere represents the whole color body, where one pole is black, the other pole is white, and the color circle is around the equator. If you follow a meridian from the black pole, the color will gradually increase in strength to its maximum brilliance and then seamlessly continue to become brighter all the way to white. Less saturated colors are inside the sphere. The axis through the middle of the sphere between the poles contains all grays from black to white. Thus, the hue is represented by the longitude, the lightness by the latitude, and the saturation by the proportion from the surface to the center black-white axis of the sphere. You can rotate the sphere either by dragging the surface, or using the arrow keys. The scroll wheel takes you inside the sphere.

In the default usage, clicking a color in the sphere will print out its RGB and HSL (hue, saturation, lightness) color coordinates. However, the main purpose is to use it as a color picker from within other python programs.
