Hello,
I've read the forum. I found that one can change the dashboard's background color using the dark.css.
Hi, Old post I know. But you can find out the CSS that the page is using by looking at the source.
Its right at the top and will look like this:
form stylesheet="dark.css" autoCancelInterval="90" isVisible="true" objectMode="SimpleDashboard" onunloadCancelJobs="true" refresh="300"
:)
