Can you reproduce the bug on the Gitea demo site?

Yes

Description

The light theme does not make a difference between preprocessor directives (.cp) and comment lines (.cm):

.chroma .cm { color: #999988; } /* CommentMultiline */
.chroma .cp { color: #999999; } /* CommentPreproc */
.chroma .cpf { color: #999999; } /* CommentPreprocFile */

This makes the code difficult to read :

.cp (and possibly .cpf) should be different than comments.

For example (I am not an artist, so the values below are not a suggestion :-) :

.chroma .cp { color: #109295 } /* CommentPreproc */
.chroma .cpf { color: #4C4DBC; } /* CommentPreprocFile */

Allow to have a more readable code :
