The signed statement for the intro, the signed artwork for the third BD story and the unusual coloring indicates to me that William Overgard did everything. The cover depiction of BD has standard colors. Inside BD's shirt is yellow and his pants are purple without diamonds. This makes me believe Overgard did it all his way.
