Why are my numbers only showing up as on a grayscale?

let html = ''; let red; let green; let blue; let randomRGB; let RGBvalue

for (let i = 1; i <= 1000; i++ ) {

RGBvalue = Math.floor(Math.random() * 256); randomRGB = rgb( ${RGBvalue}, ${RGBvalue}, ${RGBvalue} ); html += <div style="background-color: ${randomRGB}">${i}</div>;

}

document.querySelector('main').innerHTML = html;

Your code is never setting the red, green, blue variables. So setting rgb() with the same value for r,g,b it is only creating grey. Try this:

let html = '';
let red; let green; let blue; let randomRGB; let RGBvalue

for (let i = 1; i <= 1000; i++) {

  red = Math.floor(Math.random() * 256);
  green = Math.floor(Math.random() * 256);
  blue = Math.floor(Math.random() * 256);
  randomRGB = `rgb(${ red }, ${ green }, ${ blue })`;
  html += `<div style="background-color: ${randomRGB}">${i}</div>`;
}

document.querySelector('main').innerHTML = html;
