;;; This file enforces consistency in the visual style:

;;; - search highlight, search lazy follow the same color code.
;;; - diffs (ediff, smerge, etc.) follow the same color code.

;;; To find the variable associated to a currently used color, place the cursor
;;; on it and call `describe-face'. Or browse the `list-faces-display'.
