Does a QR Code Have to be Black and White

Jonathan Palley Oct 13, 2025

QR codes are an essential tool for connecting the physical and digital worlds quickly and efficiently. But one question often comes up when designing a QR code: does it have to be black and white?

The short answer is no. While traditional QR codes are typically black on a white background, they certainly don't have to be. With the right design principles, QR codes can be fully customized in color, shape, and even style. All while remaining functional and scannable.

Let’s explore how color plays into QR code design, what’s possible, and what you need to watch out for.

Why QR Codes Started as Black and White

When QR codes were first developed in 1994 by the Japanese company Denso Wave, they were created to be scanned quickly and accurately by machines. Black and white offered the highest contrast possible, making the codes easy to read by early QR code scanners. At the time, this high contrast was crucial for the technology to work consistently.

Even today, the contrast between the QR code’s “modules” (the tiny squares that make up the pattern) and the background remains one of the most important aspects of scannability. However, modern scanners, especially those found in smartphones, are much more advanced and capable of recognizing a broader range of styles and colors.

Truth About Colored QR Codes

Modern QR codes do not have to be black and white. You can use any colors you like. As long as you maintain a few important design principles.

The most important rule is to maintain contrast between the QR code and its background. This usually means using a darker color for the code itself and a lighter color for the background. For example, a navy blue QR code on a white background will generally scan just as well as a black one.

What you want to avoid is reversing that scheme such as a light yellow QR code on a dark background. Most scanners will struggle with that configuration because the code becomes harder to detect.

Design Possibilities with Colored QR Codes

Color opens the door to creative, branded, and eye-catching designs. Here are some popular ways companies and creators use color in QR codes:

Brand Colors: You can match your QR code to your business’s color palette to create a more cohesive look across marketing materials.
Gradients: When used carefully, gradient color schemes can make QR codes look more dynamic and modern.
Logos and Icons: Some QR codes feature a company logo in the center. With proper error correction, this is not only possible but very effective.
Custom Shapes: While still maintaining the square layout, some QR generators allow stylized corners or patterns for a unique appearance.

Design Guidelines to Keep Your QR Code Scannable

Creativity is encouraged, but function must come first. Here are a few best practices when designing a colored QR code:

Ensure high contrast between foreground and background.
Avoid light colors for the QR modules themselves.
Use error correction (preferably Level H) so the code still works if partially obscured by a logo or printed on uneven surfaces.
Test across multiple devices before finalizing the design.
Avoid inverted QR codes (light code on dark background), unless you've thoroughly tested them.

Following these principles ensures that your QR code remains not just beautiful, but reliable.

Why Use Colored QR Codes?

Aside from aesthetics, colored QR codes offer several strategic advantages:

Brand Recognition: A custom-colored QR code aligned with your brand identity reinforces brand consistency.
Increased Engagement: Visually appealing QR codes are more likely to grab attention and encourage scans.
Professional Appeal: A well-designed QR code signals that you’ve put thought and effort into your materials.
Differentiation: In a sea of black-and-white codes, a uniquely colored one stands out.
