Observation Details

Keyboard focus of outline (ghost) button changes background color. Difference between default (#FFFFFF) and focused (#E6E6E6) state does not meet minimum contrast ratio (3:1). Instead, the difference is barely visible at 1.2:1.

Remediation Notes

Ensure enough contrast (3:1) between different radio button states (default, focused, active, ...).

Better approach: Use non-color indicator additionally to eliminate contrast issues. This can be an outline.
