Please try the following syntax and make sure you have hook-supported react(> 16.8) & react native(> 0.59) versions installed . I'll close this issue for now. If you have any further concerns or questions, feel free to reopen this issue.

function test() {
  const hsvColorPicker = useRef(null);
  const getColor = () => {
    console.log(hsvColorPicker.current.getCurrentColor());
  };
  return (
    <>
      <HsvColorPicker
         ref={hsvColorPicker}
         // more props...
      />
      <TouchableOpacity onPress={getColor}>
         <Text>Get Current Color</Text>
      </TouchableOpacity>
    </>
  );
}
