True Color (16 million colors) support in various terminal applications and terminals

Colors in terminal

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

  • plain ascii
  • ansi escape codes (16 color codes with bold/italic and background)
  • 256 color palette (216 colors + 16 gray + ansi) (colors are 24bit)
  • 24bit true color ("888" colors (aka 16 milion))
printf "\x1b[${bg};2;${red};${green};${blue}m\n"
