For some reason the colors do not work on mozilla firefox. If I want to save the seed and have access to all functionalities I have to access this website on chrome. It's not a terrible hassle, but I thought it worth mentioning.

EDIT: My apologies, it's merely that hatching and color are incompatible. Please ignore. I'm leaving this here in case anyone else happens to have a similar problem. I'll delete if you feel it's superfluous.
