Halloween Update - New colors

Happy Spooktober to y'all!

To celebrate upcoming Halloween, I've created 6 new color sets for the occasion. This adds around 1000+ new individual assets, and will conclude the development of the Retro Diner Tiles pack. No more major updates are planned, but I might fix some minor issues and/or add one or two new color sets someday.

Thank you for your time, and keep an eye on my other projects!
