React-native-image-picker (customButtons)

Question

I'd like to change the customButtons text color, anyone knows how to do it?

  var options = {
  title: 'Select Avatar',
  customButtons: [
    {name: 'fb', title: 'Choose Photo from Facebook'},
  ],
  storageOptions: {
    skipBackup: true,
    path: 'images'
  }
};

e.g the standard color is black and I'd like to change it to blue in the title: 'Choose Phot from Facebook'.

Thanks in advance,
