Visual information needed to identify user interface components and their states, and the parts of graphics needed to understand content, have a contrast ratio of at least 3 to 1 against adjacent colours, except inactive components, components whose appearance is set by the user agent and not changed by the author, and graphics whose particular presentation is essential.
This control maps to 3 controls across 1 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
The graph holds this control, the 3 it maps to, and the evidence behind each claim, over MCP and REST.
