* The definitive list of colour numbers stored in terminal
* attribute words is kept here. It is:
*
* - 0-7 are ANSI colours (KRGYBMCW).
* - 8-15 are the bold versions of those colours.
* - 16-255 are the remains of the xterm 256-colour mode (a
* 216-colour cube with R at most significant and B at least,
* followed by a uniform series of grey shades running between
* black and white but not including either on grounds of
* redundancy).
* - 256 is default foreground
* - 257 is default bold foreground
* - 258 is default background
* - 259 is default bold background
* - 260 is cursor foreground
* - 261 is cursor background
