Choosing the right hues for your barcodes can greatly impact how efficiently and accurately they are scanned. Selecting the best barcode colours ensures easy readability by scanners, minimising errors and speeding up the scanning process. This article delves into why choosing optimal barcode colours is important and what factors should be considered for effective scanning. 

The above images show acceptable barcode colour combinations that scanners can easily read and decode.

Why Optimal Barcode Colours Matter

Picking the right colours for your barcodes is essential to make sure they stand out from their background and are swiftly and accurately scanned. Ideal barcode colours are typically high-contrast combinations, such as black on white or white on black, which allow scanners to easily read the barcode. Colours that are too similar can result in scanning mistakes and delays, as scanners might struggle to differentiate between the barcode and its background. Additionally, choosing the right barcode colours is vital for readability under different lighting conditions. For example, if a barcode needs to be scanned in low-light conditions, using colours that offer good contrast can significantly enhance scanning accuracy. Conversely, overly bright or reflective colours can create glare, making it hard for scanners to read the barcode. 

Is It Possible to Use a Coloured Background for My Barcode? 

Yes, you can print your barcode on a coloured background, but it's crucial to use a light colour to ensure high contrast between the black bars and the background. Avoid using black as the background because scanners cannot detect the left and right white ‘quiet zones’.

The best combination is black bars on a white background, but some other colour combinations can also work. However, not all colours are suitable. Here are some guidelines:

White and warm colours (yellow and red) are invisible to barcode scanners, making them appropriate for the barcode background.

Black and cool colours (blue, purple, green, and dark brown) are visible to barcode scanners, making them suitable for the vertical barcode bars.

Contrast is key. The vertical bars should be printed in a darker colour than the background to ensure readability. We recommend testing your printed barcode label with different barcode scanners to ensure it is easily readable, as scanners can vary slightly in their colour calibrations.

By opting for high-contrast colour combinations, considering lighting conditions, and accounting for the requirements of the scanning technology, you can ensure that your barcodes are easily readable and can be scanned swiftly and accurately.
