1376If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1377their act together, rxvt-unicode will support C<rgba:rrrr/gggg/bbbb/aaaa>
1378(recommended, but B<MUST> have 4 digits/component) colour specifications,
1379in addition to the ones provided by X, where the additional A component
1380specifies opacity (alpha) values. The minimum value of C<0> is completely
1381transparent). You can also prefix any color with C<[a]>, where C<a> is on
1382to four hex digits specifiying the opacity value.
1383
1384You probably need to specify B<"-depth 32">, too, and have the luck that
1385your X-server uses ARGB pixel layout, as X is far from just supporting
1386ARGB visuals out of the box, and rxvt-unicode just fudges around.
