Contrast
AMA performs a contrast check between the component background and its children for tappable elements like Pressable, Button, etc. The check is performed on the component children and sub children up to a depth level of 5.
The minimum contrast ratio expected is at least 4.5:1, and by default, this is a mandatory requirement. While the enhanced contrast of at least 7:1 is a suggestion and therefore prints only a warning if it fails.
tip
Both Log level type and max depth level can be customised, here for more info
