Random Color Picker


#1

For step 4 asks =

That’s not a very friendly way to display a color!

In Random, find the method named formatColor. This method transforms an rgb array into something a bit more readable.

Inside of the

, instead of simply using this.state.color, call the formatColor function and pass in this.state.color as an argument

When i apply this =

formatColor(ary) {
return ‘rgb(’ + ary.join(’, ') + ‘)’;


{this.formatColor(this.state.color)}


}

Nothing changes. Is this correct?

Thanks.

const rgb = this.state.color;
return rgb.reduce((a,b) => a+b) < 127 * 3;
}

applyColor() {
const color = this.formatColor(this.state.color);
document.body.style.background = color;
}

chooseColor() {
const random = [];
for (let i = 0; i < 3; i++) {
random.push(Math.floor(Math.random()*256));
}
return random;
}

render() {
return (


<h1 className={this.isLight() ? ‘white’ : ‘black’}>
    </h1>
  </div>
);

}
}

ReactDOM.render(

Can you find a way to make it more readable? There is something in New Users along those lines.
