Can't get past the first set of instructions on "Call this.setState from Another Function"

[bpastena]

I’m stuck on the the following exercise:

Call this.setState from Another Function

1. Before the render method, give Toggle a constructor() method. Toggle’s constructor() method should have one parameter, named props.
   Inside the body of the your constructor method, call super(props); On a new line, still inside the body of your constructor method, set this.state equal to this object: { color: green }. Use the example as a guide.

The step 1 instructions keeps turning red when I try to run but I’m not getting an error and I’m blind to what I’m missing in order to move to step 2.
Please help?

import React from 'react';


const green = '#39D1B4';
const yellow = '#FFD712';

class Toggle extends React.Component {
  constructor(props){
    super(props);
    this.state = { color: green };
  }
  render() {
    return (
      <div>
        <h1>
          Change my color
        </h1>
      </div>
    );
  }
}
