1.4 Distinguishable
Make it easier for users to see and hear content including separating foreground from background.
Overview
Content must be distinguishable to understand and operate it. If you can't tell a form field is required because its only indicator is that the text is red (and you have a red-green color deficiency), then you won't be able to tell the difference between required and optional form fields.
Checks if your content is distinguishable:
- People who are color blind need additional indicators to color use as well as good color contrast between the foreground text and background colors or patterns.
- People with low vision need to be able to resize text to make it legible, which includes avoiding text-heavy images.
- Both people with low vision or motor disabilities can benefit from easy to view links, buttons, and controls.
- Audio and video players should have the ability to pause or stop audio content that lasts more than 3 seconds, so the audio information does not conflict with assistive technology.
