A color overlay (similar to a piece of rubylith)

The original selection is left unprotected by this
mask. By default, Quick Mask mode colors the
protected area using a red, 50% opaque overlay.

tool from the toolbox, or select a filter or
adjustment command from the menu bar. By
default, painting with black adds to the mask,
