1353additional 72 colours. The first 64 of those (with indices 16 to 79)
1354consist of a 4*4*4 RGB colour cube (i.e. I<index = r * 16 + g * 4 + b +

1377If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1378their act together, rxvt-unicode will support C<rgba:rrrr/gggg/bbbb/aaaa>
1379(recommended, but B<MUST> have 4 digits/component) colour specifications,
1380in addition to the ones provided by X, where the additional A component
1381specifies opacity (alpha) values. The minimum value of C<0> is completely
1382transparent). You can also prefix any color with C<[a]>, where C<a> is on
1383to four hex digits specifiying the opacity value.
1384
1385You probably need to specify B<"-depth 32">, too, and have the luck that
1386your X-server uses ARGB pixel layout, as X is far from just supporting
1387ARGB visuals out of the box, and rxvt-unicode just fudges around.
1388
1389For example, the following selects an almost completely transparent red
1390background, and an almost opaque pink foreground:
