[AUCTeX] Syntax color in math-mode

[Colin Baxter]

Hello,

Has the syntax coloring in math mode changed recently? I notice that the
exponent symbol ^ is now colored a very dark red, which makes it difficult to
read against my black background. How can I get back to the original
lighter coloring?

I am using the latest git pull version of auctex and emacs-25.1.1.

Thanks,

Colin.

Yes, that changed a few days ago and this is described in the news
section of the manual
(https://www.gnu.org/software/auctex/manual/auctex.html#Changes):

* AUCTeX is able to display several levels of super- and subscripts,
each one raised above and a bit smaller than its basis. For this
feature, have a look at the customize options
'font-latex-fontify-script' (especially the new values
'multi-level' and 'invisible') and
'font-latex-fontify-script-max-level'. Also, the script characters
'^' and '_' are also fontified with a special face named
'font-latex-script-char-face'. See Fontification of math, for
details.

So you may want to customize `font-latex-script-char-face'. I suggest
you to keep it different from the rest of the equation, in order to
better highlight those characters.

Bye,
Mosè

Dear Mosè,

Thank you for the information.
