## Description

This widget provides a simple button with a preview showing the color.

On click a GtkColorSelectionDialog is opened. Additionally the button supports Drag and Drop and has a right-click menu that allows to choose the color from the current FG or BG color. If the user changes the color, the "color_changed" signal is emitted.
