SAN JOSE, Calif., May 22, 2018 (GLOBE NEWSWIRE) – The Bureau of Internet Accessibility (BoIA) has announced the release of its new automated color contrast tool, the Color Contrast Accessibility Validator. The tool is offered free of charge and is intended for use by website owners and developers to test their web pages for color contrast issues that may hamper use for the visually impaired.

BoIA’s Color Contrast Accessibility Validator sets itself apart from competing tools primarily because of its ease of use and straightforward protocols, allowing the user to immediately know which text is not meeting accessibility guidelines. For each error it encounters, the tool displays a variety of useful information so that users can quickly figure out how to fix the error, such as:

  • The current contrast ratio of the text and the required contrast ratio
  • Background and text colors, as well as their RGB and hexadecimal values
  • Font information such as style, size, line weight and height
  • Text content and associated HTML code to help easily locate the problem
  • The percentage by which the contrast ratio must be increased in order to meet the minimum requirements

The web-based tool was developed to help businesses ensure that their websites comply with Web Content Accessibility Guidelines (WCAG) 2.0 Directive 1.4.3, the technical standard that states that website text and Text images should have a minimum contrast ratio of 4.5: 1. Exceptions include large scale text, which has a minimum 3: 1 ratio, and text in logos and decorations, which has no minimum requirement.

Using a high contrast ratio for a website’s color scheme is important in order to fully serve people with color blindness, low vision, and other visual impairments. More than 3 million Americans are visually impaired, a number that is expected to more than double to 8 million over the next 30 years. In order to adequately meet the needs of this growing population and meet the requirements set by laws such as the Americans with Disabilities Act, high contrast color combinations are an important part of making any website accessible.

The tool is available free to the general public at https://color.a11y.com. For more information on this and other WCAG requirements, or to find out how you can improve the accessibility of your website, visit BoIA.org.
