On a mobile device a color blind user may not be using AT. Therefore it seems impossible to satisfy the 3:1 plus the allowance for underlining only on hover or focus.

When using touch+AT, note that focus/hover is not always triggered (e.g.
no "focus" event is fired when the AT's focus moves to an item, no :focus CSS pseudo-classes are applied). Currently, it seems that only VoiceOver/iOS fires focus/applies :focus, while other combinations (TalkBack/Android, Narrator/Windows 10 Mobile) don't. See https://patrickhlauke.github.io/touch/tests/results/#mobile-tablet-touchscreen-assistive-technology-events

However, the AT will generate and display its own fairly heavy-weight focus indication/outline, so this is less of a problem in practice.

Also, don't forget scenarios where an actual keyboard (e.g. external bluetooth keyboard paired with the phone) is used - see https://patrickhlauke.github.io/touch/tests/results/#mobile-tablet-keyboard-mouse-events
