Hi everyone, I am writing a fantasy series about witches. It's set in a high fantasy world. To get magic powers in this fantasy world, a girl has to voluntarily transform into a magical being. This has the side effect of making her skin turn bright green. I was wondering how many girls would actually take magic powers on these terms? Because humans don't have DNA like birds and fish, we cannot naturally be bright green, so everyone in that world would know that the witches are magical. They can disguise their green skin temporarily by using magic, but it is a hassle to do so.

The magic in this world enables witches to fly, to get animal familiars, to heal other people by magic, to turn their enemies into animals, to cast fireballs and lightening bolts, and much more besides. The harder spells do have an energy cost, so a witch must rest and get her energy back after doing something impressive by magic.

My question is, is this price for magic high enough? Who would take these powers if it meant getting green skin? Who would take these powers if it meant further disfigurements that are more serious than getting green skin (like distorted facial features, warts, hair loss etc.)

This question is just for girls. The magic rules for guys in this fantasy universe are different.
