Observation Details
Carousel pagination buttons rely on color difference to differentiate button states. Color contrast ratio between selected and unselected button is 2.9:1, thus not meeting minimum requirement of 3:1.
Remediation Notes
Different states of interactive elements like buttons should not solely rely on color difference. Ideally another visual indicator like border or shape is used in addition to change of color.
If no other indicator is used, the different colors must meet minimum contrast ratio of 3:1.
