My Solution to the Refactor Challenge

Very Pleased with only 5 lines, but I feel like there should be a way to reduce further, with the repetitions?

let html = '';
let eachChannel = () => Math.floor(Math.random() * 256);
let betterRGB = () =>`rgb( ${eachChannel ()}, ${eachChannel ()}, ${eachChannel ()} )`;
for ( let i = 1 ; i<=10 ; i++ ) { html += `<div style="background-color: ${betterRGB()}">${i}</div>`;}
document.querySelector('main').innerHTML = html;

Any thoughts or suggestions?
