That actually looks fairly similar to my own "dark mode":

        (defun reverse-face (face &optional frame)
          "Set FACE (in FRAME) to RGB inverse."
          (interactive (list (read-face-name "Reverse face" (face-at-point t))))
          (require 'color)
          (ignore-errors
            (let ((fg (face-attribute face :foreground frame))
                  (bg (face-attribute face :background frame)))
              (set-face-attribute
               face frame
               :foreground (color-complement-hex fg)
               :background (color-complement-hex bg)))))

        (defun toggle-dark-mode ()
          "Toggle dark mode."
          (interactive)
          (dolist (face '(mode-line default))
            (reverse-face face)))
