1485The RGB cube uses indices 16..79 (16..231) using the following formulas:
1486
1487 index_88 = (r * 4 + g) * 4 + b + 16 # r, g, b = 0..3
1488 index_256 = (r * 16 + g) * 16 + b + 16 # r, g, b = 0..15

1491steps (1/26 to 25/26 in 1/26 steps) - black and white are already part of

1511=head2 ALPHA CHANNEL SUPPORT
1512
1513If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1514their act together, rxvt-unicode will do it's own alpha channel management:
1515
1516You can prefix any colour with an opaqueness percentage enclosed in
1517brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
1518(0-100) that specifies the opacity of the colour, where C<0> is completely
1519transparent and C<100> is completely opaque. For example, C<[50]red> is a
1520half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
1521is the recommended format to specify transparency values, and works with
1522all ways to specify a colour.
1523
1524For complete control, rxvt-unicode also supports
1525C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
1526specifications, where the additional C<aaaa> component specifies opacity
1527(alpha) values. The minimum value of C<0000> is completely transparent,
1528while C<ffff> is completely opaque). The two example colours from
1529earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
1530C<rgba:0000/ff00/0000/f332>.
1531
1532You probably need to specify B<"-depth 32">, too, to force a visual with
1533alpha channels, and have the luck that your X-server uses ARGB pixel
1534layout, as X is far from just supporting ARGB visuals out of the box, and
1535rxvt-unicode just fudges around.
1536
1537For example, the following selects an almost completely transparent black
1538background, and an almost opaque pink foreground:
1539
1540 @@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
1541
1542When not using a background image, then the interpretation of the
1543alpha channel is up to your compositing manager (most interpret it as
1544transparency of course).
1545
1546When using a background pixmap or pseudo-transparency, then the background
1547colour will always behave as if it were completely transparent (so the
1548background image shows instead), regardless of how it was specified, while
1549other colours will either be transparent as specified (the background
1550image will show through) on servers supporting the RENDER extension, or
1551fully opaque on servers not supporting the RENDER EXTENSION.
1552
1553Please note that due to bugs in Xft, specifying alpha values might result
1554in garbage being displayed when the X-server does not support the RENDER
1555extension.
