did you type 'dark trim white walls' in the houzz and google search boxes?

Yes, and found the results pretty limited.

I think it is a lot of work to paint woodwaork so IMO white or wood is the way to go unless you just paint it all the same color as the walls which is what I did where the woodwork really was nothing special As for white getting dirty I would rather see the dirt that have it all grunchy for someone else to see.
