I'm making a resourcepack that also has discord color-scheme GUI, which makes text readability on those GUIs very bad. For vanilla MC texts I can fix that by putting §f (color code for white) before the text in the lang file, but this doesn't seem to work for your mod.

I don't know if this is something that even can be added, but it would definitly be nice.

The lang file in my RP has this: "text.graves.players_grave": "§f%s's grave" , but doesn't change anything.

This should work on latest at least, if it's not the case please report it again!
