1460If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1461their act together, rxvt-unicode will support C<rgba:rrrr/gggg/bbbb/aaaa>
1462(recommended, but B<MUST> have 4 digits/component) colour specifications,
1463in addition to the ones provided by X, where the additional A component
1464specifies opacity (alpha) values. The minimum value of C<0> is completely
1465transparent). You can also prefix any color with C<[percent]>, where
1466C<percent> is a decimal percentage (0-100) that specifies the opacity of
1467the color, where C<0> is completely transparent and C<100> is completelxy
1468opaque.

1470You probably need to specify B<"-depth 32">, too, and have the luck that
1471your X-server uses ARGB pixel layout, as X is far from just supporting
1472ARGB visuals out of the box, and rxvt-unicode just fudges around.
