1422specifies opacity (alpha) values. The minimum value of C<0> is completely

1424C<percent> is a decimal percentage (0-100) that specifies the opacity of
1425the color, where C<0> is completely transparent and C<100> is completelxy

1428You probably need to specify B<"-depth 32">, too, and have the luck that
1429your X-server uses ARGB pixel layout, as X is far from just supporting
1430ARGB visuals out of the box, and rxvt-unicode just fudges around.
