The hit area, but if the visual indicator of the control is the only way to identify This success criterion does not require that controls have a visual boundary indicating However, the component must not lose contrast with the adjacent colors,Īnd non-text indicators such as the check in a checkbox, or an arrow graphic indicatingĪ menu is selected or open must have sufficient contrast to the adjacent colors. For example, there is not a new requirement that visited linksĬontrast with the default color, or that mouse hover indicators contrast with theĭefault state. States of an individual component meet the 3:1 contrast ratio when they do not appear This Success Criterion does not require that changes in color that differentiate between
