Thanks for your advice. I'm now thinking that an NSScrollView with a list of custom views should be quite straightforward. >> Whenever a color object is added or removed (from a house), I'll need to >> create or remove the associated custom color view.

I'm glad that you mentioned this. I believe that I can also bind an NSArrayController to the core data entity, then KVO-observe the arrangedObjects property. Thanks!
