Color Contrast is an important issue because Website accessibility is an important issue. Websites must be designed to be accessible to everyone, including disabled people – otherwise, you losing part of your audience – and you are breaking the law. I.e., The Equality Act 2010, which states that you are not allowed to discriminate against disabled people. So, a critical aspect of website accessibility is color contrast. In this blog post, I will explore the role of color contrast in accessible web design and outline tips and strategies to improve color contrast on your website.
What is color contrast?
Color contrast refers to the difference in color between two elements, such as text and its background. It is measured using a ratio, between the text’s color and the background color. The higher the ratio, the better the color contrast. For example, 1:1 is white on white and 21:1 is white on black. Color contrast is essential in web design because it affects the readability and legibility of content.

Why is color contrast important for accessibility?
People with visual impairments, such as color blindness, rely on color contrast to navigate and understand content on websites. If the color contrast is insufficient, they may not be able to distinguish between different elements on the page, making it challenging to complete tasks or access information. Additionally, color contrast is essential for people with cognitive impairments, who may find it difficult to read or understand content with low color contrast.
Accessibility guidelines and laws related to color contrast
Many countries have accessibility laws that require websites to be designed with accessibility in mind. In the UK, the Equality Act 2010 requires businesses to ensure their websites are accessible to people with disabilities. The Web Content Accessibility Guidelines (WCAG) outline the standards for website accessibility, including color contrast. The UK also has British Standard 8878 (BS 8878) is the Web Accessibility Code of Practice developed by the British Standards Institution, which is a standard aiming to introduce website accessibility to non-technical professionals, including.
How to check color contrast
Several tools are available online to check color contrast, such as the WebAIM Contrast Checker and the Contrast Ratio Checker. These tools provide a ratio between the text and background colors, indicating whether the color contrast is sufficient.
Tips for improving color contrast
- Use high-contrast color schemes: High-contrast color schemes, such as black and white, are easier to read and understand for people with visual impairments. Avoid using low-contrast color schemes, such as light gray text on a white background.
- Avoid color combinations that are difficult to distinguish: Some color combinations, such as red and green, can be challenging for people with color blindness to distinguish. Use color palettes that are accessible, such as blue and yellow.
- Use text alternatives for non-text content: Non-text content, such as images and videos, should have text alternatives, such as alt tags, that describe the content. This allows people with visual impairments to understand the content.
Color contrast is an essential aspect of accessible web design. Use higher-contrast color schemes, avoid color combinations that are difficult to distinguish, and provide text alternatives for non-text content. By making your website accessible, you are ensuring that more people can access your content including disabled people.
