M-x ansi-term colors in Emacs 24.x

I have noticed that some colors in LS_COLORS don't work when running a shell inside M-x-ansi-term in Emacs. For exmaple; di 00 94 is supposed to turn on bold on light blue on directories on LS_COLORS (see a list of the codes here ), but ansi-term in Emacs does not show it in color. In fact, only the simple colors listed on that website seem to work under ansi-term in Emacs, while they work perfectly well on my regular gnome terminal. Is there a way to get ansi-term to recognize the so called **extra** colors? Where/how can I look up the colors supported by ansi-term in Emacs?
