But it's a lot more complex than you might imagine. For example, there must be at least one background color-set active.
Couldn't you solve this by setting the very first one to "on", and then disabling the on/off part of it? That would make it impossible to turn the first one "off". [Alternatively, you could just not have on on/off for the first color set, to reflect the fact that the first one is not "optional".]
