DISCLAIMER: This project used to change the CSS of the Scratch website. In other words, it would make the site look different. This glitch has now been patched If the buttons at the bottom of your screen don't change, reload the page. Unfortunately, the colors do not change when you press them.
If you want to learn how to do this, @fortyonegames has a tutorial on the basics: https://scratch.mit.edu/projects/1311303013/
