Very interesting floor. What is it?

I'd go with the lightest yellow.

I would suggest going with more of a tan color. Possibly a light tan to match the lighter tones in the flooring you have.

Go with the grout color for a uniform look. Bring in black accents to anchor room e.g., black planter pots for plants, etc. furniture? Modern? Black leather?

Don't paint the walls the same color as the floor. You'll feel like you're living in a paper bag.

Have you thought about keeping the walls a bright white throughout and adding a few accent walls in bright colors like an aqua blue or greens?

HI -- With these floors , which are just perfect and beautiful ! The floors are the star so the walls should just be a warm white very light tan . Never yellow ... that would be wrong !
