Styling React Native Picker

I'm attempting to style the text color of the items in a React Native picker. I've only been working in iOS so far, but if I could find a cross-platform solution that'd be awesome.

I've tried the following things:

Styling color on Picker

<Picker style={{color:'white'}} ...etc >

Styling color on Picker Items

<Picker.Item style={{color:'#fff'}} label={'Toronto'} value={'Toronto'} />

I've also seen some examples of adding a color property, so I tried this

<Picker.Item color='white' label={'Toronto'} value={'Toronto'} />

At a total loss here. Thanks for any insight!

EDIT:Here's a solution - use itemStyle prop in the Picker element. I believe this is iOS only.

<Picker itemStyle={{color:'white'}} ><Picker.Item color='white' label={'Toronto'} value={'Toronto'} /><Picker.Item  label={'Calgary'} value={'Calgary'} /></Picker>
