A neat dynamic glow effect for images

This will be a quick one. I've wondered for a while how Spotify do their dynamic colours from an album cover, so went down a rabbit hole. While I might look into a more accurate way , I discovered a neat trick for getting that dynamic glow effect on an image.

Simply stack an image on top of a second copy of that image with some absolute positioning, and blur the image underneath! Pretty fun effect. Just don't forget to hide your "blurred" image with an aria-hidden="true" so screen readers don't call it out unnecessarily.
