Colours in terminal

It's a common confusion about terminal colours... Actually we have this:

  • plain ascii
  • ansi escape codes (16 colour codes with bold/italic and background)
  • 256 colour palette (216 colours + 16 ansi + 24 gray) (colors are 24bit)
  • 24bit true colour ("888" colours (aka 16 milion))
