# ImGuiWindow.ColorPicker

> Appends a RGBA color editor to an ImGuiWindow and stores the callback. Missing or nil color components default to 1.0. When the rendered editor changes, the callback is queued and later invoked with red, green, blue, and alpha. The method returns the same ImGuiWindow object.
