Here's a question for ya'all :

If markings on fur, skin, or scales that were made from paint, berry juice, blood, or anything else that could stain and soak, would they stay on there forever? For instance, if they were on the fur/scales/skin for a few days, weeks, or months, (or even years) then would the markings still be able to be washed away? How long would one have to wait for it to be impossible, or near impossible, for stains to be washed away by water or any other kind of liquid. What's the most water/liquid-proof, and what liquid is the best at using for getting rid of stains? What's the most stain-proof and the most-liquid proof, fur, skin, scales, what (talking about stuff that would be found on animal surfaces, but you can do plant and in-animate object surfaces too for add-ons )?

Take a look at 's wolves, they have some kind of paint or berry juice or berry paint on their faces, what are the limits for something like that? What if Okami Amaterasu's markings from the game Okami weren't "natural" and were actually made of some kind of juice or paint or something that stains and soaks, what would be the limits for that?

Take this into consideration, folks, and answer carefully (make sure your absolutely positive when you answer).
