How to create gradient fog?

Hello I wanted to create Gradient fog like in this image.

Maybe a post-processing effect called “Vignette” will do something like this?

This is the correct answer, it doesn’t look like the reference image uses fog.

But for an overview of how to modify the THREE.js fog, this video is great.
