Sherwin-Williams Agreeable Gray (SW 7029)

The best-selling paint color in North America, and for good reason — Agreeable Gray is a warm greige (gray-beige) that makes real estate agents weep with joy and designers grudgingly respect. It's the perfect "I don't know what color to paint" color because it genuinely works everywhere. The warm undertone prevents the cold, depressing feel of true grays. Home stagers use it as a default because it photographs well and appeals to every buyer demographic. It's not exciting, but it's never wrong.
