You can change it to go back to transparent if you don't like the normal hue. I have heard that the ethy's could be a different color, but the chances are rare. I own all the ethy's all the way up to the cu. They are all normal colors of the actual animal, so it looks like I am mounted my pet. Accept, I can ride the ethy Cu, and have my Pet Cu follow me. There are no charges on the brush, and anyone can use it as long as it is in your backpack. If you would like to paint your ethy's and you don't trust me, you are welcome to find a trustworthy middle person that could do it for us. I am cool with that.
