1183 In addition to the colours defined above, rxvt offers an additional 72
1184 colours. The first 64 of those (with indices 16 to 79) consist of a
1185 4*4*4 RGB colour cube (i.e. *index = r * 16 + g * 4 + b + 16*), followed
1186 by 8 additional shades of gray (with indices 80 to 87).
1187
1188 Together, all those colours implement the 88 colour xterm colours. Only
1189 the first 16 can be changed using resources currently, the rest can only
1190 be changed via command sequences ("escape codes").

1201 ALPHA CHANNEL SUPPORT
1202 If Xft support has been compiled in and as long as Xft/Xrender/X don't
1203 get their act together, rxvt-unicode will support
1204 "rgba:rrrr/gggg/bbbb/aaaa" (recommended, but MUST have 4
1205 digits/component) colour specifications, in addition to the ones
1206 provided by X, where the additional A component specifies opacity
1207 (alpha) values. The minimum value of 0 is completely transparent). You
1208 can also prefix any color with "[a]", where "a" is on to four hex digits
1209 specifiying the opacity value.
1210
1211 You probably need to specify "-depth 32", too, and have the luck that
1212 your X-server uses ARGB pixel layout, as X is far from just supporting
1213 ARGB visuals out of the box, and rxvt-unicode just fudges around.
1214
1215 For example, the following selects an almost completely transparent red
1216 background, and an almost opaque pink foreground:
1217
1218 rxvt -depth 32 -bg rgba:0000/0000/0000/2222 -fg "[e]pink"
1219
1220 *Please note that transparency of any kind if completely unsupported by
1221 the author. Don't bug him with installation questions!*
