vterm colors

[lejeunel]

I confirm that...

• I searched the FAQ, issue tracker, discussions board, documentation, and wiki, and found nothing about my issue.

• I read the debugging guide and researched the issue to the best of my ability.

• My issue can be observed on the latest available commit of Doom.

• My issue can be observed on a stable release of Emacs (i.e. doesn't end in .50, .60, or .9*)

Describe your issue

I notice that vterm buffers do not respect the theme colors.

If my understanding is correct, looking at vterm-color-palette gives me the set of color variables (vterm-color-red, vterm-color-green,... ) that should be picked up by vterm. Next, choosing a theme should inject values in these variables. I can verify that the colors are properly setup through the describe-face menu.

However, the colors appear to be wrong, and more precisely, they seem to correspond to the term-color-* colors instead. Looking at the following screenshot, where a vterm buffer is displayed on the right side, I notice that the colors are darker. This correlates with the bottom window (describe-face) that shows the hue difference between term-color-blue and vterm-color-blue.

Am I experiencing a bug here? Could anyone help me understand the logic by which vterm chooses/sets colors?

Steps to reproduce

1. Install Emacs 30.2
2. Install doom 3.0.0-pre
3. Following the docs, install libvterm using home-manager using package emacs.pkgs.vterm
4. Open a vterm buffer
