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.
