The wall board gadget on the gadget listing shows with a black background and white text. When I add it it gives me a white backgound with black text, like a normal board. For readability it's easier to have white text on black, especially from far away (we use electronic boards) - how do I configure this? We are using a downloaded JIRA instance v5.1.6#785-sha1:8d9ee55 and Greenhopper v 6.1.2.
