I've enabled dyeing of ammunition with dye tubs. Not entirely sure why I had it blocked, but please let me know if it causes any problems!
On that note, are people using dye tubs? Do they need to be available via tinkering or something to see wider use? Dye creation through Alchemy are on my eventual todo list... just haven't gotten there yet.
