Accessibility color ui12/18/2023 According to the WCAG: “The contrast ratio of 4.5:1 was chosen for level AA because it compensated for the loss in contrast sensitivity usually experienced by users with vision loss equivalent to approximately 20/40 vision. This criterion specifies that the text should have a contrast ratio of 4.5:1. Note: You should always consult your company’s legal counsel to answer any specific questions and determine the exact requirements for your website. In that scenario, higher contrasting elements will be much easier to make out for any user. A common example is the glare on a phone when outdoors or under bright light. Issues with color contrast can be situational as well. However, a low-vision user could simply be an elderly individual, which makes it highly likely that contrast concerns apply to your website. It’s a common mistake to assume that your website doesn’t have enough users with low-vision or color deficiencies to warrant spending time and money to fix color contrast errors. But for users with low vision or color deficiencies, proper color contrast doesn’t just provide a better experience-it’s essential for them to read or understand content at all. The more readable text is, the better experience users will have with your content. Like most accessibility considerations, proper color contrast benefits all users to some extent, not just those with vision impairment. These ratios make it easy to measure and evaluate color contrast. It’s typically represented as a ratio of the relative brightness between two colors. This can be a costly mistake to fix after the fact, so it’s essential to understand color contrast and the role it plays in web accessibility when making brand color palette decisions.Ĭolor contrast is essentially the difference in light, or luminance, between the foreground and background. If you’re not considering web accessibility when choosing your brand colors, you might find that when it comes time to build your website, your color combinations don’t meet minimum accessibility requirements. One commonly overlooked accessibility consideration by brand identity designers is color contrast on screens. In reality, accessibility is a broad topic that encompasses all facets of the website creation process, from planning to launch. Web accessibility is often seen as primarily the concern of web developers to write code that meets requirements. There’s a lot of work that goes into brand development, especially choosing the right color palette.
