At this point I'd almost recommend get this recipe mod instead:
http://www.nexusmods.com/divinityoriginalsin/mods/20/?Its dye recipes are a bit harder to make, but also makes dyes infinite use, so you only need make one of each color. The creator also figured out how to make cloth helmets dyeable and added a ton more recipes.
Technically you can use my mod and his at the same time, since his uses the /main folder. But you get that stupid "corrupted: multiplayer disabled" error even though both mods work perfectly fine together
(would be nice if someone could figure out a mod that disabled that stupid error, since its never triggered on an act of real corruption).
...As a side note, is there any indication that it might be possible to easily change which parts of armor are dyed? A lot of the armor dyes the 'secondary' color but not the main color, for instance I'd much rather dye the main white part of the Sourcehunter witch robe than the flowery design at the bottom.
You can change what portions of a piece of armor change color, but it requires you to alter a somewhat tricky to edit texture file. I managed to get all my "sexy armors" setup to be dyed the way I want them, but it was a bit of a headache. Fortunately for you you will not have the Sourcehunter robe for long and the rest of the game's robes (or my robe replacement mods) are much more dye friendly.
