Change the `fill` property to change the color,

    const icons = require('./generated');
    const firstIconKey = Object.keys(icons)[1];
    const Icon = icons[firstIconKey];

    <div>
      <Icon fill="red" />
      <Icon fill="blue" />
      <Icon fill="#bada55" />
    </div>

The icons can have different size properties, ranging from 1 to 8. The default size is 2 (24px).

    const icons = require('./generated');
    const firstIconKey = Object.keys(icons)[0];
    const Icon = icons[firstIconKey];

    <div>
      <Icon size="1" />
      <Icon size="2" />
      <Icon size="3" />
      <Icon size="4" />
      <Icon size="5" />
      <Icon size="6" />
      <Icon size="7" />
      <Icon size="8" />
    </div>
