What are the hover state contrast requirements for drop down lists?


I have a dropdown list with black text in a form. Does the background bar on the hover states as you hover over each selection option require a 3.1 contrast ratio against the white container background, or can I use a light gray background bar behind each selection for the hover states (such as #E6E6E6)?


According to WCAG Success Criterion 1.4.11, when elements have a visual indication of the state they are in (focused, mouseover or selected), the visual indication must meet a 3:1 contrast ratio. This includes elements within dropdown lists, so they must have a hover and focus state that reaches a 3:1 contrast ratio with the background.
