I'm trying to create a tattoo as test and I want it to have a black border that is uncolorable. So far, I've tried making it black and white but in both cases Tattooinator doesn't display it correctly. This makes me wonder if it's even possible to have an uncolorable black border or if I'm doing something wrong?

Like, I can make Tattooinator recognize the RGBA channels successfully, it's just that the black border either gets the color of the Blue channel or becomes fully transparent, no matter what I try.

Ok, I don't think it's possible to have a non recolorable black border. I've only managed so far to make it black if I include it as one of the four channels.
