Here is a case:
I use package =hl-sexp= to highlight sexp in Lisp code:
#+begin_src emacs-lisp
(use-package hl-sexp
:ensure t
:config
(set-face-attribute 'hl-sexp-face nil
:background (cl-case (alist-get 'background-mode
(frame-parameters))
('light
(color-darken-name (face-background
'default) 7))
('dark
(color-lighten-name
(face-background 'default) 4)))
)
)
#+end_src
When I start Emacs, the face ~hl-sexp-face~ is been set by the Emacs
initialized
color-theme. Then I use package =circadian= to auto switch color-theme
or manually
switch color-theme with command =disable-theme= and =load-theme=. But
this face
~hl-sexp-face~ is defined already, usually not good for another switched
color-theme.
So I hope there is a hook for switching color-theme like
~color-theme-switch-hook~ etc.
This is useful for package =circadian=.

Vanilla Emacs doesn't use color themes. It uses custom
themes - the user theme by default. Color themes are
available through library `color-theme.el'.
Color themes:
https://www.emacswiki.org/emacs/ColorThemes
Custom themes:
https://www.emacswiki.org/emacs/CustomThemes

I don't understand the problem. Are you saying that when
you switch to another theme (presumably a custom theme)
the appearance of face `hl-sexp-face' changes?

Do you mean that after you switch to another theme you
want to invoke some code? What code would you invoke?
Is the idea just to make face `hl-sexp-face' have or
keep the appearance you want?

Here is an example showing what I want:
#+begin_src emacs-lisp
(add-hook 'color-theme-load-hook
(lambda ()
(set-face-attribute 'hl-sexp-face nil
:background (cl-case (alist-get
'background-mode (frame-parameters))
('light
(color-darken-name
(face-background 'default) 7))
('dark
(color-lighten-name
(face-background 'default) 4)))
)
))
#+end_src
Then the custom faces can be changed automatically according the
color-theme switching.

If you really are using color themes (`color-theme.el')
then you have `color-theme-mode-hook', but that likely
won't help here. There is no `color-theme-load-hook',
AFAIK.
On the other hand, if you are using custom themes then
there are `custom-new-theme-mode-hook' and
`custom-theme-choose-mode-hook'.
You have not yet made clear which kind of themes you are
using (though you keep saying "color theme"): custom
themes or color themes.

Seems I'm using `color themes`. I only have `color-theme-mode-hook`, don't
have `custom-new-theme-mode-hook`, `custom-theme-choose-mode-hook`.
Thanks for your explaination.

You're right, `color-theme-mode-hook` does not work for my purpose. And I'm
not
using CustomThemes. Themes there is no existing way to do this.
