Hi,
Here is a patch that add a X resource to color the highlighted menu
entry in the Lucid backend. There is much going on here because I
needed to understand this code and end up needed to refactor some part
to implement this feature. This was about ten clunky patches that I
finally squashed into this one.
I have tested that it works with the 2 following configuration
- --with-x-toolkit=athena
- --with-x-toolkit=athena --without-xft --without-cairo
Here is how it looks like:

This should say which widget it applies to, and that it only applies
under the Lucid build.

Please fix the coding style here so that there is at least a space
between casts and what is being casted.
I know the rest of xlwmenu.c doesn't follow that coding style strictly,
but there is no excuse to add even more incorrectly formatted code.

Please fix and re-fill the comment. We write comments like this:

Otherwise, return false. */

What I said about coding style also applies here. Also, don't write:
abc = foo_1_2 () ?
mw->core.background_pixel : foo_1 ();
but write:
abc = (foo_1_2 ()
? mw->core.background_pixel
: foo_1 ());

Motif doesn't have widget resources named topHighlightShadowColor,
bottomHighlightShadowColor, topHighlightShadowPixmap or
bottomHighlightShadowPixmap. So please delete these.

I haven't looked at the code here in much detail yet, but please verify
that it builds and works correctly under Xft, Cairo, and without either
of the two, and under a pseudo-color visual. (To get an X server with a
pseudo color visual, run "Xephyr -screen 800x800x8".)
Thanks.

I have attached a new version of my patch taking your remarks into
account but I did not remove this comment. I think it could be useful
to understand that "top_gc = something_bottom_gc" is not a typo here.
I have also done the following testing with Xft/cairo/PseudoColor
combinations:
|-------------+-----------------+-----------------+-----------------+---------------------|
| | Xft + cairo | Xft only | cairo only | None |
|-------------+-----------------+-----------------+-----------------+---------------------|
| X Truecolor | ok | ok | ok | ok but with a |
| | | | | default tiny face |
|-------------+-----------------+-----------------+-----------------+---------------------|
| Xephyr | ok but color | ok but color | ok but color | ok, colors ok, but |
| Pseudocolor | not quite right | not quite right | not quite right | with a default tiny |
| | around each | around menu | around each | face [fn:2] |
| | glyph [fn:1] | labels [fn:2] | glyph [fn:1] | |
|-------------+-----------------+-----------------+-----------------+---------------------|
* Footnotes
[fn:1] Aside from the Lucid widget, the emacs buffer is completly
blank.
[fn:2] This time the emacs buffer is here. tool-bar icons are ugly.

We have the same general pattern (random_gc = random_opposite_gc) in
most of the X code, so it is redundant IMHO. But I won't insist.

Yes, that isn't expected to work, because Cairo is broken. Also, you
can't build Emacs with both Xft and Cairo, since they're mutually
exclusive.

Could you please describe how the colors are "not quite right"?

Here and elsewhere new functions are added, the argument list should be
reformatted to not place each argument on its own line.
Thanks.

Ok. I can remove this comment then.

😅 sorry. So then "Xft + cairo" is just "cairo".

Here is how it look here™ on a PseudoColor Xephyr. This is Cairo with a
bitmap font:

FWIW, draw_shadow_rectangle, draw_shadow_rhombus… are already like that.
I'll do it but what are your recommandations? Split at fill-colum +
indent? Leave the old ones untouched?

Right, that's acceptable. I think the problem will go away if you
disable the rendering extension on the X server.

Yes. Looking at functions like `x_dnd_do_unsupported_drop' in xterm.c
should help as well.
Otherwise, LGTM.

Ok and I guess that not many people are using a PseudoColor display
nowadays.

Here is a new version of this patch. What's new:
- fix some comments
- format arguments list on both new functions and the one I have
modified their arguments
- add some forgot freeing in `release_shadow_gcs'

Thanks. One (late) last comment on the documentation:

Shouldn't this say "the menu item highlighted by the mouse"? Otherwise,
what "highlighted" means is not exactly clear.

And here, shouldn't "widget" be in plural?

I did not add "by the mouse" because menus could also be navigated with
keyboard arrows. Do you have any other suggestions to make it clearer?

Ok. I'll add it to the next patch when the previous issue is resolved.

How about "by the mouse or key navigation"?
