selection -- a gtk-color-selection widget
rgba -- a gdk-rgba color to set the previous color with

The function gtk-color-selection-previous-rgba gets the previous color. The function (setf gtk-color-selection-previous-rgba) sets the previous color.

This function should be called with some hesitations, as it might seem confusing to have that color change. Calling the function gtk-color-selection-current-rgba will also set this color the first time it is called. The function gtk-color-selection-previous-rgba is deprecated since version 3.4 and should not be used in newly written code.
