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.
