Quick Answer
A colored QR code uses a custom foreground colour instead of the standard black. UnlimitedQRCodes.com includes a free colour picker that lets you match your QR code to any brand colour. The key rule: always use a dark colour on a white or very light background — contrast is essential for reliable scanning across all lighting conditions.
Enter your URL, WiFi credentials, contact details, or text into UnlimitedQRCodes.com. The standard black QR code appears in the preview panel.
Click the colour swatch or colour picker below the preview panel. A colour selector appears.
Select your brand colour using the hex code input (e.g., #1a56db for brand blue, #166534 for brand green). Avoid light colours — yellow, pink, pale orange, or light grey will fail to scan reliably.
Your chosen colour must be dark enough against the white background. A contrast ratio of at least 3:1 is required for reliable scanning. Dark navy, dark green, dark purple, and dark red all work well. Light colours do not.

Yes — as long as the colour is dark enough. The key is contrast ratio between the QR modules and the background. A dark navy or forest green QR code on a white background scans just as reliably as a black one.
