What the model said
I'd recommend **#F5F5F5** — a light, neutral gray that works well as a background. It's softer than pure white (#FFFFFF), reduces eye strain, and provides good contrast for text and UI elements. If you want something warmer, try **#FFFAF0** (floral white), or if you prefer a cooler tone, **#ECEFF1** (light blue-gray) is popular in modern design. For dark mode, **#1E1E1E** or **#0D1117** work well.
