		1552	=head2 ALPHA CHANNEL SUPPORT
		1553
		1554	If Xft support has been compiled in and as long as Xft/Xrender/X don't get
		1555	their act together, rxvt-unicode will do its own alpha channel management:
		1556
		1557	You can prefix any colour with an opaqueness percentage enclosed in
		1558	brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
		1559	(0-100) that specifies the opacity of the colour, where C<0> is completely
		1560	transparent and C<100> is completely opaque. For example, C<[50]red> is a
		1561	half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
		1562	is the recommended format to specify transparency values, and works with
		1563	all ways to specify a colour.
		1564
		1565	For complete control, rxvt-unicode also supports
		1566	C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
		1567	specifications, where the additional C<aaaa> component specifies opacity
		1568	(alpha) values. The minimum value of C<0000> is completely transparent,
		1569	while C<ffff> is completely opaque). The two example colours from
		1570	earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
		1571	C<rgba:0000/ff00/0000/f332>.
		1572
		1573	You probably need to specify B<"-depth 32">, too, to force a visual with
		1574	alpha channels, and have the luck that your X-server uses ARGB pixel
		1575	layout, as X is far from just supporting ARGB visuals out of the box, and
		1576	rxvt-unicode just fudges around.
		1577
		1578	For example, the following selects an almost completely transparent black
		1579	background, and an almost opaque pink foreground:
		1580
		1581	@@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
		1582
		1583	When not using a background image, then the interpretation of the
		1584	alpha channel is up to your compositing manager (most interpret it as
		1585	transparency of course).
		1586
		1587	When using a background pixmap or pseudo-transparency, then the background
		1588	colour will always behave as if it were completely transparent (so the
		1589	background image shows instead), regardless of how it was specified, while
		1590	other colours will either be transparent as specified (the background
		1591	image will show through) on servers supporting the RENDER extension, or
		1592	fully opaque on servers not supporting the RENDER EXTENSION.
		1593
		1594	Please note that due to bugs in Xft, specifying alpha values might result
		1595	in garbage being displayed when the X-server does not support the RENDER
		1596	extension.
