如何在createMuiTheme中重写多字体-colorTextPrimary？

import { createMuiTheme } from '@material-ui/core/styles';

const theme = createMuiTheme({
  palette: {
    text: {
      primary: '#FF5733', // 设置您想要的颜色
    },
  },
});

export default theme;

import React from 'react';
import { ThemeProvider } from '@material-ui/core/styles';
import theme from './theme';

function App() {
  return (
    <ThemeProvider theme={theme}>
      {/* 您的应用程序内容 */}
    </ThemeProvider>
  );
}

export default App;
