This is an entirely different question, isn't it.

In *shell* and other comint based modes, you can activate interpretion
of ANSI escape codes for colorizing with 
M-x ansi-color-for-comint-mode-on RET

You can process the string with ansi-color-apply:

(ansi-color-apply
 (shell-command-to-string "echo $RED hello $YELLOW world $NORMAL"))
--> #(" hello  world 
" 0 7 (font-lock-face (foreground-color . "red")) 7 14 (font-lock-face 
(foreground-color . "yellow")))

(insert (ansi-color-apply
          (shell-command-to-string "echo $RED hello $YELLOW world $NORMAL")))
 hello  world 
  ^red    ^yellow
--> nil
