Honestly, I really like "neon" color chaos. But it shouldn't be too hard to change. If you want to try it locally, you only need to change few lines responsible for color generation:

https://github.com/Stanko/neon/blob/master/src/utils/generat...

"rng" property is a seeded random generator you can use instead of Math.random

I'll add a short section in readme about running it locally.
