and I gave you the solution. With list-faces-display you don't need to put
point anywhere to find the name of the face you are interested in.

If you do a list-faces-display you get a buffer that on one side lists the
name of all the defined faces (including tooltip) and on the other side a
sample of what that face looks like.

All you have to do to find the name of the face is scroll through the
buffer until you see a sample which matches the face your looking for (in
your case, a face with the same foreground and background colours, then you
either hit enter with point on the face name or use the mouse (instructions
at the top of the buffer) and you get a customize-face buffer where you can
set the foreground/background (and many other things.
