Description
Use case
WCAG publicshed a level AAA text color contrast that raise to 7:1.
The visual presentation of text and images of text has a contrast ratio of at least 7:1, except for the following:
Large Text
Large-scale text and images of large-scale text have a contrast ratio of at least 4.5:1;
Incidental
Text or images of text that are part of an inactive user interface component, that are pure decoration, that are not visible to anyone, or that are part of a picture that contains significant other visual content, have no contrast requirement.
Logotypes
Text that is part of a logo or brand name has no contrast requirement.
Proposal
Our current MinimumTextContrastGuideline
targets 4.5:1 for normal text and 3:1 for large text. We should add a variant of this test that target 7:1 for normal text and 4.5:1 for large text
