disabled monitors showing purple occasionally on web ui

If you click on one of these phantom purples to get the detailed
status page, is that one blue or purple ? Since no page-messages are
triggered, I suspect it's a problem with the way bbgen decides to
go purple (so I'd expect the detailed status to be blue).

Yep.  If I click on a phatom purple, the detailed status page is blue.
