Material UI - Change Button text color in theme

Question

I'm having a problem with changing the button text color directly in the Material UI theme. Changing the primary color + button font size works fine, so the problem isn't in passing the theme on. Here's my code:

import React from 'react';
import { MuiThemeProvider, createMuiTheme } from 'material-ui/styles';
import { lightBlue } from 'material-ui/colors';
import styled from 'styled-components';

const theme = createMuiTheme({
  palette: {
    primary: lightBlue, // works
  },
  raisedButton: {
    color: '#ffffff', // doesn't work
  },
  typography: {
    button: {
      fontSize: 20, // works
      color: '#ffffff' // doesn't work
    }
  }
});

const App = ({ user, pathname, onToggleDrawer }) => (
  <MuiThemeProvider theme={theme}>
    ...
  </MuiThemeProvider>
);

I also tried using an imported color instead of the #ffffff, but that had no effect either.

Anybody got any ideas?

Solved it! This finally did the trick:

const theme = createMuiTheme({
  palette: {
    primary: lightBlue,
  },
  overrides: {
    MuiButton: {
      raisedPrimary: {
        color: 'white',
      },
    },
  }
});

So, you just have to use "overrides" and be explicit about the exact type of component you want to change.
