You can modify the colors for defined faces in the.emacs file. For
example, I have the following within the (custom-set-faces ...) section:
'(font-lock-comment-face ((((class color) (background light))
(:foreground "Blue" :italic nil))))
'(font-lock-constant-face ((((class color) (background light))
'(font-lock-doc-string-face ((((class color) (background light))
'(font-lock-string-face ((((class color) (background light))
'(font-lock-type-face ((((class color) (background light))
Beware any line wrap of the above. These colors, etc. work for me, but
may not be pleasing for others. I should also note, that I have the
buffer background set to white, which I prefer, but I know others have
differing colors in use.
If you use:
M-x customize-group <RET> font-lock-faces <RET>
that will get you to the appropriate settings for the highlighting
colors, etc. If you adjust the settings there and use 'Save for future
sessions', the updates will be saved in .emacs. If you use the 'Set
for current session', the changes should be made to your current
working session, without having to exit and restart emacs. If you just
want to play around for the current session, without affecting new
sessions, just use the latter until you get things the way you want.
