Ambilight effect

The Ambilight Effect is a feature in certain TVs that projects colors onto the wall behind the screen. Here is my attempt to recreate the effect with CSS.

Unfortunately, the filter only works in the Chrome browser.

To create the “Ambilight” effect in SVG, the filter region is increased to 300% and centered to prevent clipping. The process utilizes feOffset to copy the source graphic, applies feColorMatrix to saturate colors and remove dark pixels, uses feMorphology to spread bright colors, applies feGaussianBlur to blur the effect, and finally combines it with the original image using feComposite.
