I had the very blurry textures problem but i found out that it was from a previous mod that i had. I then uninstalled the game and reinstalled it again. Then when i reinstalled your mod into the files, it worked perfectly.
Nice work it's still a shame we have to choose the colors ourselves but the mod is super well done if not
