Below are photos of Tansy, the character from my opening and Willow from the old TV series Buffy the Vampire slayer. I believe they are quite similar in terms of how the are represented.
Most obvious thing they have in common is that they both practice witchcraft in a modern day setting. Rather than being like a typical witch that you might see in fairy tales with the familiar broom, black costume, cat and being typically 'evil'.
Both Characters wear quite neutral colours - brown, beige combined with natural hair (long) and little or no jewelry. The dress is relatively ordinary but a little bit alternative. This suggests that she on the whole fits in, but can't be called mainstream.
In the series Willow is quite a geeky girl who through her intelligence becomes a powerful witch. She only uses her power for good until her partner is killed. After that Willow goes out of control and relies more and more on witchcraft, becoming a danger to those around her.
Tansy, begin using witchcraft to benefit her partner but just like Willow becomes dependent on its use and again this ends up with bad consequences for those around her.
Willow until the ends of the Buffy series was always seen as a geeky, plain girl who happened to develop an special power. Ensy from the opening is seen a more threatening. The spinning sequence shows that there is something different about her. The use of black up with it getting meshed up and caught on the teeth is more in line with a gothic type witch and then there's the similar eye shots with the dog adding a supernatural and animalistic quality to her portrayal.
