Hello, I have the following problem with Emacs *in a terminal* (emacs -nw) This configuration *does* works (red over transparent background) (global-whitespace-mode t) (set-face-background 'whitespace-space nil) (set-face-foreground 'whitespace-space "red") This one *does not* work (the background is grey): (global-whitespace-mode t) (set-face-attribute 'whitespace-space nil :background nil :foreground "red") However, it should be the same, right? Interestingly, it works with eval-region though. Thanks for your help! Regards, Kip
