The gtk:color-chooser-widget widget lets the user select a color. By default, the chooser presents a prefined palette of colors, plus a small number of settable custom colors. It is also possible to select a different color with the single-color editor. To enter the single-color editing mode, use the context menu of any color of the palette, or use the '+' button to add a new custom color.

The chooser automatically remembers the last selection, as well as custom colors. To change the initially selected color or to get the selected color use the gtk:color-chooser-rgba function.

The gtk:color-chooser-widget widget is used in the gtk:color-chooser-dialog widget to provide a dialog for selecting colors. The gtk:color-chooser-widget class has a single CSS node with name colorchooser. This example shows a color chooser widget in a window. The selected color is print on the console.
