title: How can I specify a default color for a react-native-elements button?
body: <p>Right now I am using the <strong><a href="https://github.com/react-native-community/react-native-elements" rel="noreferrer">react-native-elements</a></strong> component library for my app. Specifically I am using their Button component, which has a default color of grey applied to it. </p>

  <p>How can I set a custom default color for these buttons without having to pass in style props every time? </p>
  
  <p>Is there a simple function/method I can call, or do I have to look at creating a custom component to wrap it? I would prefer the former.</p>
