First change all the bulbs to LED 4000K that will help you choose the right wall color that will not change at night. Do you love all the trim ? I like the FP surround trim but IMO the rest is not worth high lighting so I would do it in the same color as the walls but in semigloss . I love the house and the floors the stone on the FP not so much IMO you have huge space so why is the TV in the corner. I am not sure about the size of that room but if you post that then maybe we can show you how to have 2 seating spaces in a big space one for TV and one for the FP A floor plan of the whole house would be great.

Once you have changed out those light bulbs, would you please post new pictures, so we can see the rooms better. Right now, those light bulbs are casting a yellow cast on everything.
