                 brighten, factor
              or brighten

         brighten the current palette by the specified FACTOR.
         The FACTOR is the slope of the transfer function for the color value
         (see to_hsv for a description of the hsv color system); a value of
         1.0 always remains 1.0, but values near 0.0 change by FACTOR.
         FACTOR= 1.0 is a no-op.  The default factor is 4.0.
