		1502
		1503	If Xft support has been compiled in and as long as Xft/Xrender/X don't get
		1504	their act together, rxvt-unicode will do it's own alpha channel management:
		1505
		1506	You can prefix any color with an opaquenes percentage enclosed in
		1507	brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
		1508	(0-100) that specifies the opacity of the color, where C<0> is completely
		1509	transparent and C<100> is completely opaque. For example, C<[50]red> is a
		1510	half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
		1511	is the recommended format to specify transparency values, and works with
		1512	all ways to specify a colour.
		1513
		1514	For complete control, rxvt-unicode also supports
		1515	C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
		1516	specifications, where the additional C<aaaa> component specifies opacity
		1517	(alpha) values. The minimum value of C<0000> is completely transparent,
		1518	while C<ffff> is completely opaque). The two example colours from
		1519	earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
		1520	C<rgba:0000/ff00/0000/f332>.
		1521
		1522	You probably need to specify B<"-depth 32">, too, to force a visual with
		1523	alpha channels, and have the luck that your X-server uses ARGB pixel
		1524	layout, as X is far from just supporting ARGB visuals out of the box, and
		1525	rxvt-unicode just fudges around.
		1526
		1527	For example, the following selects an almost completely transparent black
		1528	background, and an almost opaque pink foreground:
		1529
		1530	@@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
		1531
		1532	When not using a background image, then the interpretation of the
		1533	alpha channel is up to your compositing manager (most interpret it as
		1534	transparency of course).
		1535
		1536	When using a background pixmap or pseudo-transparency, then the background
		1537	colour will always behave as if it were completely transparent (so the
		1538	background image shows instead), regardless of how it was specified, while
		1539	other colours will either be transparent as specified (the background
		1540	image will show through) on servers supporting the RENDER extension, or
		1541	fully opaque on servers not supporting the RENDER EXTENSION.
		1542
		1543	Please note that due to bugs in Xft, specifying alpha values might result
		1544	in garbage being displayed when the X-server does not support the RENDER
		1545	extension.
