Distinguishable

Excerpt from W3C: Understanding Guideline 1.4: Distinguishable

While some guidelines are focused on making information available in a form that can be presented in alternate formats, this guideline is concerned with making the default presentation as easy to perceive as possible to people with disabilities. The primary focus is on making it easier for users to separate foreground information from the background. For visual presentations, this involves making sure that information presented on top of a background contrasts sufficiently with the background. [1]
