		1638
		1639	If Xft support has been compiled in and as long as Xft/Xrender/X don't get
		1640	their act together, rxvt-unicode will do its own alpha channel management:
		1641
		1642	You can prefix any colour with an opaqueness percentage enclosed in
		1643	brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
		1644	(0-100) that specifies the opacity of the colour, where C<0> is completely
		1645	transparent and C<100> is completely opaque. For example, C<[50]red> is a
		1646	half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
		1647	is the recommended format to specify transparency values, and works with
		1648	all ways to specify a colour.
		1649
		1650	For complete control, rxvt-unicode also supports
		1651	C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
		1652	specifications, where the additional C<aaaa> component specifies opacity
		1653	(alpha) values. The minimum value of C<0000> is completely transparent,
		1654	while C<ffff> is completely opaque). The two example colours from
		1655	earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
		1656	C<rgba:0000/ff00/0000/f332>.
		1657
		1658	You probably need to specify B<"-depth 32">, too, to force a visual with
		1659	alpha channels, and have the luck that your X-server uses ARGB pixel
		1660	layout, as X is far from just supporting ARGB visuals out of the box, and
		1661	rxvt-unicode just fudges around.
		1662
		1663	For example, the following selects an almost completely transparent black
		1664	background, and an almost opaque pink foreground:
		1665
		1666	@@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
		1667
		1668	When not using a background image, then the interpretation of the
		1669	alpha channel is up to your compositing manager (most interpret it as
		1670	transparency of course).
		1671
		1672	When using a background pixmap or pseudo-transparency, then the background
		1673	colour will always behave as if it were completely transparent (so the
		1674	background image shows instead), regardless of how it was specified, while
		1675	other colours will either be transparent as specified (the background
		1676	image will show through) on servers supporting the RENDER extension, or
		1677	fully opaque on servers not supporting the RENDER EXTENSION.
		1678
		1679	Please note that due to bugs in Xft, specifying alpha values might result
		1680	in garbage being displayed when the X-server does not support the RENDER
		1681	extension.
