gtk:color-selection-current-rgba (object)

object -- a gtk:color-selection widget
rgba -- a gdk:rgba instance for the color to set the color with

The accessor for the current-rgba slot of the gtk:color-selection class gets or sets the color in the color selector. The first time this is called, it will also set the original color to be rgba too. This function is deprecated since version 3.4 and should not be used in newly written code.
