Do you have base boards? The quarter round should match the base boards. If you don't have them, I might have the quarter round match the floors.

The best look is to match the baseboards imo. Also base shoe (or shoe) moulding offers a better appearance than quarter round.

I took my builder's advice and stained the moulding to match the floor. He said that if we painted it white to match the baseboard, it would show the many nicks and scratches made by vacuum cleaners and any other object that may bump up against it. He was right -- no marks on the baseboard and you can't tell where I have bumped up against it with the vacuum.

I like both looks. Personally we had white baseboards with white molding and cherry floors. We will do the same thing with new house. After seeing this pic I am about to rethink but since I am doing slate in other rooms and I like things to match, I will stick with white quarter round. You cannot go wrong with either,
