/**
* A Color Ring widget provides an intuitive way to specify a color.
* The outer ring of the widget is rotated to control the hue of the color
* being specified, while the inner triangle varies the color saturation
* and the brightness of the color. The color saturation axis of the
* triangle goes from a fully saturated "pure" color to "pastel" color;
* the brightness goes from black to a bright color.
