Garry,

Try doing it in the Red channel.  Mask the area you want to affect, then
reduce the brightness of the area you have masked.  This will reduce the
amount of red.
For a mask that 'tapers' toward the edge use a fountain fill as a mask.  To
see this checkout this tutorial  http://www.unleash.com/mikeb/graymask/
