.SH DESCRIPTION
.B cg-sleepmode
gradually fade out the red, green, and blue channels on the
monitors to the brilliances of
.IR red-luminosity ,
.IR green-luminosity ,
and
.IR blue-luminosity ,
respectively, whose default values are 0.25, 0, and 0,
respectively. A value of 0 means complete darkness, a
value of 1 means normal brilliance.
.P
