Witches have changed, but also have become contradictory?

       One of the contemporary representations of the witch that comes to mind for me is The White Witch from The Chronicles of Narnia series. In the series, she is a powerful witch who wields magic, is immortal, and controls a large territory and many "monstrous" creatures as her minions. In many ways, the white witch differs greatly from the role of the witch in the early modern period as discussed by Palmer. The white witch rather than being some lowly peasant or any lowly being for that matter, is instead a strong powerful amazonian like woman, who wields enormous power and influence. She is also in my opinion, very attractive in her representation in the movie(not sure about the book). Normally, when most people think of the stereotypical witch, I assume we picture an old ugly woman, with warts and a long crooked nose. But instead, more recently, it seems to me that witches are becoming more and more eroticized in their depictions and representations. This makes me wonder, if the witches in the early modern period who were often depicted as being incestuous and committing many indecent acts with demons and even the devil himself, if that set of characteristics has manifested into witches being portrayed as sexually appealing as a way to represent empowerment. Many of the accused witches in the early modern period seemed to enjoy the freedom and the fear they caused the dominant authorities of the time with their retelling of their sexually devious deeds, so I see a relation between the modern representation of the witch as an erotic powerful woman as a manifestation of that early modern period depiction of a witch.

      On an aside, I find it quite strange that she is the "white witch", and yet is an evil witch. Normally, the color white is often associated with purity and goodness, but in this case, we associate within the realm of Narnia, that the color white is evil, cold, and devoid of goodness. For example, in the Wizard of Oz, the good witch is dressed in glowing white garments while the wicked witch of the west rocks an all black outfit. This is use of color scheme to induce in its viewers an associated connotation is a very old and common concept that is prevalent in many cases. But in the instance of the white witch, to me this drastically deviates from the norm and I can't for the life of me figure out if there is some deeper meaning behind it or not, and I really feel like there is. I would appreciate any comments or thoughts as to what this contradiction could imply or mean.
