71 * The #GtkColorSelection is a widget that is used to select
72 * a color. It consists of a color wheel and number of sliders
73 * and entry boxes for color parameters such as hue, saturation,
74 * value, red, green, blue, and opacity. It is found on the standard
75 * color selection dialog box #GtkColorSelectionDialog.
