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"

View tmux-24.diff
This diff is a modified version of a diff written by Arnis Lapsa.
[ The original can be found here: https://gist.github.com/ArnisL/6156593 ]
This diff adds support to tmux for 24-bit color CSI SRG sequences. This
allows terminal based programs that take advantage of it (e.g., vim or
emacs with https://gist.github.com/choppsv1/73d51cedd3e8ec72e1c1 patch)
to display 16 million colors while running in tmux.
The primary change I made was to support ":" as a delimeter as well

Good afternoon fellow space travelers, thanks for coming along on this mission. We still have about a week
before we arrive at New Zlorpia, so please return your stasis tubes to their original upright position and
prepare for your mission briefing.
We are going to be negotiating a trade agreement with the Zlorpians for their supply of Farkle seeds. They
have a much different way of counting than we do, and I'm concerned that if we don't have a good way to
work with their number system, we'll be at a disadvantage in negotiations. Let me explain:
The zlorpians have a single arm that comes out of their forehead, with a hand that has 3 fingers. As a
result, our base-10 way of counting (based on our ten fingers) is as alien to them as their way is to us.
You can’t perform that action at this time.
