I recently suggested to the authors of Forestry that they support Animania wool types in their recipes (ForestryMC/ForestryMC#1974); they did so, and also noted that Forge doesn't automatically register a blockWool type in the dictionary. They recommended that Animania registers it, and then adds the various wools to the dictionary for ease of future compatibility... so I'm suggesting that here. 😄

aaaand I just saw that they referenced it themselves. I have GOT to start searching the issues list first. >_<
