What is the secret behind Soundcloud's ability to generate stunning background gradients from album art?

I'm looking to create a similar impact on my website and am curious about the most straightforward way to do so.

For reference, here's an example of what I have in mind:

Answer №1

const image = document.getElementById('myImage');

/*
Utilizing ColorThief Library - Find it here: https://github.com/lokesh/color-thief/
*/
const colorThief = new ColorThief();
const paletteColors = colorThief.getPalette(image, 2); //Returns an array containing 3 colors in RGB format

const section = document.getElementsByClassName('myContainer')[0];

section.style.backgroundImage = '-webkit-linear-gradient( to left top, rgb(' + paletteColors[0].join(',') + '), rgb(' + paletteColors[1].join(',') + '), rgb(' + paletteColors[2].join(',') + ')'; //Works best on webkit browsers like Chrome or Safari
