 Accessibility is the secret for businesses to unlock a new world of inclusivity, diversity, and equity for their audience. One of the essential components of digital accessibility is the proper color contrast. The use of efficient colors helps readers with visual impairments to better understand the content. Hence, many companies look forward to using professional accessibility color checkers.

This write-up delves into the role of color contrast especially for businesses aiming at accessible digital solutions in 2024. We’ll understand the importance of color contrast in accessibility, the dedicated WCAG guidelines for color contrast, and more in this guide.

Importance of color contrast in accessibility

To start with, color contrast refers to the difference between the luminance or brightness between the two colors. When talking about digital content, color contrast refers to the contrast between the text and the background colors. Having a high contrast ensures proper readability.

The use of accessibility contrast checkers helps businesses achieve proper color contrast for their digital content. The key factors stressing the importance of color contrast cover the following:

• Accessible digital content

First and foremost, the use of color contrast checkers ensures that people with temporary and permanent impairments can quickly interpret and understand the digital content. It promotes the use of accessible digital content for people with impairments and general audiences accessing content in different lighting conditions.

• Complying with the standards

The dedicated accessibility standards accepted legally encompass the Web Content Accessibility Guidelines (WCAG). These guidelines offer specific criteria for color contrast to promote web accessibility. So, businesses adhering to these standards get the advantage of preventing any possible accessibility lawsuits.

• Improved user experience

The overall user experience for the general audience and people with impairments significantly increases with the proper color contrast. Users get more legible and easy-to-navigate content which helps people with temporary and permanent impairments alike.

WCAG color contrast guidelines

After having a quick look at the color contrast importance, here are the key Web Content Accessibility Guidelines (WCAG) 2.1 for maintaining a proper color contrast:

• “Level AA”

It is the standard level of accessibility compliance under WCAG. For “Level AA” compliances of color contrast, it is 4.5:1 for normal text against the background and at least 3:1 for the large text. The large text here refers to 18pt or 14pt bold text.

• “Level AAA”

This is an advanced level of accessibility. When checked with the accessibility contrast checkers, the contrast ratio must be at least 7:1 for the normal text. The same ratio is 4.5:1 for large text. “Level AAA” guidelines offer challenging but enhanced accessibility benefits. 

• “Exceptions”

It refers to the exception of the graphics and decorative text in meeting the color contrast in the digital content. However, the user interface and key information components must always adhere to the WCAG guidelines.
