+colours and 8-bit colour palette used by ANSI terminals such as @code{xterm} on
+@code{rxvt-unicode} in 256-colour mode.
+The most common use case is when using 24-bit colours in a terminal emulator
+which only support 8-bit colour palette.  This package allows true-colours to 
be
+approximated by values supported by the terminal.")
