The Emacs manual says:

--8<---------------cut here---------------start------------->8---
@cindex @env{INSIDE_EMACS} environment variable
  Emacs sets the environment variable @env{INSIDE_EMACS} in the
subshell to @samp{@var{version},comint}, where @var{version} is the
Emacs version (e.g., @samp{24.1}).  Programs can check this variable
to determine whether they are running inside an Emacs subshell.
--8<---------------cut here---------------end--------------->8---

I suppose you are not using a comint-derived mode for your shell then.

True, but wouldn’t it be nicer to use font-lock with customizable faces
instead of forcing a certain choice of colours on Emacs users?
