Are You Implementing Good Contrast in Colors for Web Accessibility?

The Importance of Contrast Colors

The color of text and images must be different from the background they are placed over to be visible. This difference is called contrast. For example, black text on a white background has a high color separation and is easy to read. On the other hand, light gray text on a white background would provide low differentiation and would be difficult to differentiate. 

The insufficient distinction between hues can be annoying for ordinary readers but is an insurmountable obstacle for those with limited vision. Developers and business executives will miss out on the full readership potential because of the limitations for disabled individuals who:

• Could struggle to read instructions or labels, especially in forms or navigation
• May not see the text at all
• Might not be able to tell clickable elements apart

Good Contrast in Colors is a Good Practice for All Web Development

Ensuring good contrast in colors is a win-win for everyone. Not only are you creating a more inclusive online experience for people with disabilities, but general users also appreciate easy readability. 

Reach more consumers and clients by making content and interface elements more accessible. As mobile devices become more widely used for accessing the internet, it’s crucial to take into consideration how bright sunlight can impact your pages. Strong hue distinctions make it easier to view words, images, and buttons in the washout effect of the sun.

Following best practices that enhance inclusivity also has a positive impact on a brand’s reputation. Users are more likely to return to a site that is simple to navigate and either purchase products or acquire information. A professional and attractive design establishes trust from the moment someone lands on your page.

Meet viewers’ expectations by incorporating good contrast in colors in your web design. This is a simple development step that enables companies to provide the best possible experience to all visitors.

How Is It Measured?
Developers check color contrast using a simple ratio:

• 1:1 = lowest (like white text on a white background)
• 21:1 = highest (like black text on a white background)

WCAG guidelines include recommended ratios to ensure readability: 

• Normal text (small to medium size): must have at least 4.5:1
• Large text (18pt or 14pt bold and up): needs at least 3:1
• Buttons and other UI elements: also need 3:1

These Web Content Accessibility Guidelines are an internationally recognized set of standards for creating accessible online content for users with disabilities.
