Here's my first attempt at making mods. Chromatic ores adds rosite, marigolite, dandelite, fernite, irisite, and wisterite, which are all ores that correspond to a color of the rainbow. There is currently a basic set of tools and armor for each one. If I get more familiar with modding I may add more content but as of now I have no idea. Thanks for checking it out!
