		1551	=head2 ALPHA CHANNEL SUPPORT
		1552
		1553	If Xft support has been compiled in and as long as Xft/Xrender/X don't get
		1554	their act together, rxvt-unicode will do its own alpha channel management:
		1555
		1556	You can prefix any colour with an opaqueness percentage enclosed in
		1557	brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
		1558	(0-100) that specifies the opacity of the colour, where C<0> is completely
		1559	transparent and C<100> is completely opaque. For example, C<[50]red> is a
		1560	half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
		1561	is the recommended format to specify transparency values, and works with
		1562	all ways to specify a colour.
		1563
		1564	For complete control, rxvt-unicode also supports
		1565	C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
		1566	specifications, where the additional C<aaaa> component specifies opacity
		1567	(alpha) values. The minimum value of C<0000> is completely transparent,
		1568	while C<ffff> is completely opaque). The two example colours from
		1569	earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
		1570	C<rgba:0000/ff00/0000/f332>.
		1571
		1572	You probably need to specify B<"-depth 32">, too, to force a visual with
		1573	alpha channels, and have the luck that your X-server uses ARGB pixel
		1574	layout, as X is far from just supporting ARGB visuals out of the box, and
		1575	rxvt-unicode just fudges around.
		1576
		1577	For example, the following selects an almost completely transparent black
		1578	background, and an almost opaque pink foreground:
		1579
		1580	@@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
		1581
		1582	When not using a background image, then the interpretation of the
		1583	alpha channel is up to your compositing manager (most interpret it as
		1584	transparency of course).
		1585
		1586	When using a background pixmap or pseudo-transparency, then the background
		1587	colour will always behave as if it were completely transparent (so the
		1588	background image shows instead), regardless of how it was specified, while
		1589	other colours will either be transparent as specified (the background
		1590	image will show through) on servers supporting the RENDER extension, or
		1591	fully opaque on servers not supporting the RENDER EXTENSION.
		1592
		1593	Please note that due to bugs in Xft, specifying alpha values might result
		1594	in garbage being displayed when the X-server does not support the RENDER
		1595	extension.
