1438=head2 ALPHA CHANNEL SUPPORT
1439
1440If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1441their act together, rxvt-unicode will support C<rgba:rrrr/gggg/bbbb/aaaa>
1442(recommended, but B<MUST> have 4 digits/component) colour specifications,
1443in addition to the ones provided by X, where the additional A component
1444specifies opacity (alpha) values. The minimum value of C<0> is completely
1445transparent). You can also prefix any color with C<[percent]>, where
1446C<percent> is a decimal percentage (0-100) that specifies the opacity of
1447the color, where C<0> is completely transparent and C<100> is completelxy
1448opaque.
1449
1450You probably need to specify B<"-depth 32">, too, and have the luck that
1451your X-server uses ARGB pixel layout, as X is far from just supporting
1452ARGB visuals out of the box, and rxvt-unicode just fudges around.
1453
1454For example, the following selects an almost completely transparent red
1455background, and an almost opaque pink foreground:
