Thanks everyone for your replies and feedback!
glad to have such a positive reaction to this witch (name pending)
I will definitively go with purple thanks a mix of democracy and the fact that fits her magical nature.
@TheNiceZombie I tested the change in the cape and hair and worked really well!.
@Rodimus13 sorry for the extremely delayed reply here is her personality description:
she is a cheerful girl with a great sense of curiosity and love for pranks, this often leads her to trouble, danger and many adventures.
one of the main reasons she play pranks is out of curiosity of people`s reactions, but aside her pranks she is really emphatic with others, sometimes to ridiculous degrees. Seing someone crying can make her cry easily.
Her curiosity led her to study magic while most people may be afraid of the dangers of reckless or malicious use of it and how can affect the users and the people around.
When trying to solve problems she tends to try "the fun way" which is not always the most practical one. In part to see if her crazy ideas work and because it can be amusing.
she tends to ask many questions when she gets interested in a new topic, which can be annoying for some people.
while she is really skilled at using magic, she is still young and naive about the universe and prone to ocasionally mess up her spells, specially when she gets too excited or upset.
She rarely studies her magic in a formal academic way, but her pranks and adventures seem to work as "practice" for her. She struggles with the theoric part of magic. she can make a spell work after a few tries, but she cant explain her proccess and often comes up with casual terms like "magithingie".
