change color using JavaScript (DOM)

 const box = document.getElementsByClassName('box');
 let colorAsString = '#FEC6F0';
 let colorAsNumber = #FEC6F0;
    Array.from(box).forEach((element) =>{
        element.style.backgroundColor = colorAsString;
        element.style.backgroundColor = colorAsNumber;
    });

I stored a hex-color value in string as well as a number and pass the variable as a value for css property.
Why this code not work can you explain me…!
