What the model said

I'd suggest **#f5f5f5** — a light neutral gray that's comfortable for long viewing, provides good contrast for text, and works well with most design systems. It's slightly warmer than pure white (#ffffff) which can cause eye strain.

If you want something with a bit more personality, **#f0f4f8** (soft blue-gray) or **#faf9f6** (warm cream) are also popular for modern interfaces.
