There is a nice built-in Emacs feature to colorize strings with ANSI color escape sequences. So evaluating the following Elisp code, will insert the "Test text" at the point with proper colors.

(require 'ansi-color)
(insert (ansi-color-apply "^[[33mTest text^[[0m"))

enter image description here


I tried to use the ansi-color-apply function to colorize the results of my Org Babel code blocks using :post with the following filter block.

#+begin_src emacs-lisp :var input="[33mTest text[0m" :results raw

    (ansi-color-apply input)


#+RESULTS: ansi-colorize
Test text

Which only removes the color escape sequences, but the inserted text has no proper face attributes.:

Since ansi-color-apply is a pure function, therefore does its job right and returns with:

#("Test text" 0 9 (font-lock-face (foreground-color . "#E6DB74")))

Which does not have the expected effect when the result is inserted by Org Babel
