> I agree that `get-char-property` is the key ingredient, and it would be prudent to steer users to that function.  It does, however, require an advanced level of Lisp expertise to understand how to use it to achieve certain goals.  I probably wouldn't have been able to figure out (in a reasonable period of time) how to get foreground/background at point without standing on the shoulders of others -- e.g., `foreground-color-at-point` and `background-color-at-point`.

get-char-property gets you the face, and then face-foreground and
face-background (both documented in the ELisp manual) can be used to
get the colors.
