SW Passive . I like gray with wood.

The blue might be nice in the kitchen, but for the living room I would choose a warm off-white, although the SW Passive that celerygirl posted is also very nice. If you want a more modern look, consider painting the mantel a white or off-white color and painting the gold inserts black. Drapes in a cream color would look nice.

Ingrid gave nice idea of FP painting.

You can also go with black and gray for FP

Thank you all!

Celerygirl, those images really help. I still feel like nothing goes with those orange floors. Too bad we are on a limited budget and won't be changing the flooring for now.

I wonder if Benjamin Moore Revere Pewter will work better with these floors?

I have SW Gateway Gray at 50% in my kitchen with floor & cabinets similar to your tones. Click on the link; mine looks like the night time version, only at 50%.
