Best Colors for QR Codes — Contrast Rules That Always Scan

Last updated: November 5, 2025 · 5 min read

Golden rules

• Dark foreground on a light background (e.g., #111 on #fff).
• Avoid low-contrast pairs (light gray on beige).
• Keep a clean white quiet zone (margin) around the code.
• Test print + scan under different lighting.

Gradients & brand colors

Gradients can work if the darkest areas remain dark enough and modules are crisp. Avoid reversing colors (light modules on dark background) unless you have strong contrast and printers that hold detail well.

Try your palette in QRBuilder and switch between light/dark themes to preview real-world contrast.
