elisp - Confused when setting an Emacs face -


enter image description here (set-face-attribute 'diredp-dir-heading nil '(t (:foreground blue :background dark1)))

what should right statements set face? bow//

face attributes :foreground , :background must have string values.

so try "blue" instead of blue etc.

the error message see saying asked emacs evaluate blue, means find value variable. emacs tried , found symbol blue has no value variable. string "blue", on other hand, evaluates itself, , string kind of value needed here.
