What the model said

I'd suggest **#F5F5F5** — a light gray that's neutral, easy on the eyes, and works well for most designs. 

If you want something warmer, **#FFFEF7** (off-white with a slight cream tone) is also popular. For dark mode, **#1A1A1A** is a solid dark gray background.

What's the context — web design, UI, or something else? I can tailor the recommendation if needed.
