I've got a color from user in #RRGGBB hex format (#D3D3D3 is light grey) and I'd like to color some output with it. I imagine I write print("some text", color="#0000FF") and get blue colored output. Is it possible (ideally without 3rd party software)?

  • It depends. Truecolor ansi escapes are supported by some Unix/Linux terminal emulators. Where are you needing these? – Antti Haapala -- Слава Україні Aug 20 '17 at 13:45
  • @AnttiHaapala I'm working on program that gets photo and prints it as ASCII art. Using Ubuntu. – M. Volf Aug 20 '17 at 13:54

You can use the following escape sequences on a true-color aware terminal:

  • ESC[ … 38;2;<r>;<g>;<b> … m Select RGB foreground color
  • ESC[ … 48;2;<r>;<g>;<b> … m Select RGB background color

Thus you can write a function:

RESET = '\033[0m'
def get_color_escape(r, g, b, background=False):
    return '\033[{};2;{};{};{}m'.format(48 if background else 38, r, g, b)

and use this like:

print(get_color_escape(255, 128, 0) 
      + get_color_escape(80, 30, 60, True)
      + 'Fancy colors!' 
      + RESET)

You can get doubled horizontal or vertical resolution by using for example ▀ and both background and foreground colour.

  • Not working for me, but it looks like I don't have _true-color aware terminal_ (LXTerminal). Will try it in somewhere else and then maybe accept answer. Btw. this is good test of your terminal: https://askubuntu.com/a/790991 – M. Volf Aug 21 '17 at 09:41
