const UserList = ['U', 'Lucy', 'Tom', 'Edward'];
|

const colorList = ['#f56a00', '#7265e6', '#ffbf00', '#00a2ae'];

class Autoset extends React.Component {
|

const index = UserList.indexOf(this.state.user);

this.setState({

user: index < UserList.length - 1 ? UserList[index + 1] : UserList[0],
|
|
color: index < colorList.length - 1 ? colorList[index + 1] : colorList[0],
