Shouldn't it be

const unprocessedRippleColor = android_ripple?.color ?? 'transparent';

?

I don't really see the point of defaultRippleColor in that case.

defaultRippleColor is required to properly replicate the behaviour of RN Pressable.
When android_ripple is set, but the color field is not provided, we want to set color to undefined, so that it uses the default system value (opaque whiteish).
When android_ripple is not set, we want to remove the ripple altogether, which is done via 'transparent'.

return IS_FABRIC
? unprocessedRippleColor
: processColor(unprocessedRippleColor);
}, [android_ripple]);
