@mendyEdri it looks like there's a bug in the hint/index.spec.js, you've specified color={Colors.white}, and so the background color will be white and not primary; you can test it by putting the following in the PlaygroundScreen (remove the commented lines as needed):

<Hint
  visible
  message={'Hint message to hint things'}
  position={Hint.positions.TOP}
  useSideTip
  key={'1'}
  targetFrame={{x: 10, y: 200, height: 1, width: 1}}
  onBackgroundPress={() => {}}
  // color={Colors.white}
  // removePaddings
  enableShadow
  testID={'Hint'}
/>

Should I remove the background color or change the expected result?

@M-i-k-e-l Yes, technically you can, I'm not sure if I wanted to make sure the backgroundColor can be change or not.

Let me know if my change is ok
