 Very short blog post on how I implemented a dithering and color compression effect in Unity using its new ``Render Graph API``.
 The color compression part is implemented using a simple bit shifting (by getting rid of the first ``n`` bits of the r,g,b values). This is pretty simple and straightforward
-The dithering however, was a bit more involved. I tried commenting what each part of the code does (at least in the shader part, the c# side is pretty straight forward)
