Sherwin Williams Repose Gray is a great neutral with darker, cooler undertones.
Some painters tape and Rustoleum Studio Color Stellar paint is all you need to make a bold accent wall.
For a clean white look, Sherwin Williams Extra White is what you want.
For a white that's less crisp, but still bright with no undertones, go with SW Pure White.
Benjamin Moore Brewster Gray is a blue-tinged gray that can be used for an accent wall - or all 4 walls!
Can't pick just one? Use multiple shades of the same color with geometric shapes!
A pair of pastels - like SW Romance and Vanillin - give calming, feminine vibes.
