gimp/app/widgets/gimpwidgets-utils.c
Michael Natterer ace40d125d Bug 735891 - color areas in the color picker info window are half transparent 
Add code to GimpOverlayChild which can render arbitrary children of
the widget fully opaque, ignoring the configured opacity.

Add gimp_widget_get,set_fully_opaque() which gets/sets a per-widget
boolean flag to trigger that code.

Set the color picker's and the text tool style widget's color areas to
fully opaque.
