Yes, Vulcano's module is good for testing things about crafting, although I believe Tellenger made some changes here and there. With dying, it works very well for tests. The only problem is that you have to be careful to check that the dye you want can be found in a store in-game (or with your nearest friendly DM).

An alternative that I found is to use the Pretty Good Character Creator, which allows a very fast customization. It only gives the colors' numbers, though, so it may not be easy to identify which dye corresponds to which color. But it's so easy to use that may be worth it.
