It doesn't look very white, as I expect Tudors to do with all the dark trim. In a less traditional setting I would suggest that colors be selected based on fabrics. What are the colors in your rug? Can you take a good close up of it and post so we can see the tones it it? That may be where you find the right beige or tan. Comment here and use the Photo button to add a photo with only rug, no distracting colors, and I'll try finding a color match for you.

Thanks! Here is our rug

I LOVE your room....and your coffee table!! Your room has personality! My favorite neutral is SW Nomadic Desert. I have used it in at least 6 rooms. IMO it looks good with all trim colors, and I see no undertones.

I would bring out the silvery blue color in the carpet to the walls.
