{() => {
    switch (this.state.color) {
        case "red":   return "#FF0000";
        case "green": return "#00FF00";
        case "blue":  return "#0000FF";
        default:      return "#FFFFFF"; 
    }
}()}

This doesn't work. You have to wrap the arrow function in parens as per the docs:

{(() => {
    switch (this.state.color) {
        case "red":   return "#FF0000";
        case "green": return "#00FF00";
        case "blue":  return "#0000FF";
        default:      return "#FFFFFF"; 
    }
})()}

This doesn't work.

@geoyws It's been fixed for some time now, mate. See #4471.
