In clojure, the comment character is `;`. clojure-mode syntax highlighting + color scheme greys comment text out.

I want emacs to color lines that begin with `;-;` with a different color. 

For example:

    ;; This is a normal greyed out comment, we use ;; by convention for blocks.
    ;  This is a typical grey inline comment, we use ; by convention.

    ;-; This is recognized as a comment and is normally greyed out.
    ;-; I want emacs to recognize this as something a little different and give
    ;-; it a different color.

How can I achieve this?
