Are your colors vegan friendly?

Our watercolors are crafted according to a traditional recipe. This recipe includes local honey from Umbria, which increases the colors wet-ability, brilliance and longevity. We also use a small quantity of Oxgall as a wetting agent. Ox gall is of animal origin. Animal well being is an issue important to us, and we are testing synthetic alternatives to this ingredient.
