The three topmost controls determine the red, + green and blue components while the last defines the alpha of the + gradient. You can move points, and add new ones, by clicking with the left + mouse button, and remove points by clicking with the right button. + + There are three default configurations available at the bottom of + the page that are provided as suggestions on how a color table could be + configured. +*/
