How to assign multiple variables on a single line?

class Color {
constructor(red, green, blue) {
    this.red = red;
    this.green = green;
    this.blue = blue;
}

  generateColor(){
    // this.red, this.green, this.blue = this.randomColor() ???
    return (`Random Color : \n Red : ${this.red}\n Green : ${this.green}\n Blue : 
             ${this.blue}`)
  }

  randomColor() {
    return Math.floor(Math.random() * 256);
  }
}

How can i make this kind of multiple assignment without using arrays ?
