What the model said
I'd suggest **#f5f5f5** — a light, neutral gray that works well as a background. It's easy on the eyes, provides good contrast for text and UI elements, and is professional without being stark white. If you prefer something warmer, **#faf8f3** (soft cream) is a nice alternative, or **#e6f2ff** (light blue) if you want a subtle color tint.
