i've created a palette from the 256 colors of the xterm256 palette;
- for the first 16 (which depend on terminal configuration) i've used the default VGA palette
- the others are as usual: a 24-greyscale ramp and 6×6×6 RGB color cube
- had to split it over two pages, because 12×16 wouldn't fit all colors (and could structure it a bit better, now)

i'm using this myself for a terminal roguelike game
but hope it's useful to anyone !
