Well, if fate was kind, then binding the DataListView's 
backgroundColor to dataList.backgroundColor (instead of the other way 
around) should solve the problem. (The color well should also be bound 
to dataList.backgroundColor.)

But apparently fate is not kind, since I don't see that NSTableView 
exposes 'backgroundColor' as a binding. It looks fairly easy to do 
(exposeBinding in your subclass and bindToObject: somewhere, possibly 
in your subclass) though I've never tried it. Or use 
[dataList.backgroundColor addObserver: self ...] in the DataListView 
and bypass bindings for this one property.
