Emacs 28.1 no longer uses ansi-coloir-name-vector so colours in shells no longer match the theme.

[aardvark179]

I've fixed this in my own theme that I apply on top of zenburn by defining the ansi color faces like this

  (zenburn-with-color-variables
    (custom-theme-set-faces
     'aardvark179-custom
     `(ansi-color-black ((t (t :foreground ,zenburn-bg :background ,zenburn-bg))))
     `(ansi-color-red ((t (:foreground ,zenburn-red :background, zenburn-red))))
     `(ansi-color-green ((t (:foreground ,zenburn-green :background ,zenburn-green))))
     `(ansi-color-yellow ((t (:foreground ,zenburn-yellow :background ,zenburn-yellow))))
     `(ansi-color-blue ((t (:foreground ,zenburn-blue :background ,zenburn-blue))))
     `(ansi-color-magenta ((t (:foreground ,zenburn-magenta :background ,zenburn-magenta))))
     `(ansi-color-cyan ((t (:foreground ,zenburn-cyan :background ,zenburn-cyan))))
     `(ansi-color-white ((t (:foreground ,zenburn-fg :background ,zenburn-fg))))
     ))

But this doesn't cover bright variants, and I'm not sure if darker variants should be used for the background colors.

I wonder if this is why Zenburn 2024 2.6 has atrocious bad color for ansi-color-freeze-overlay

output from C-u C-x =
