That is madness. A white girl pretending to be black and darkening her complexion is silly (a black girl lightening hers is tragic), but Floor can of course honor Mavis (and does it excellently), Arielle can be a black girl and Denzel Washington can be Macbeth.
Cultural appropriation - imitation is the sincerest form of flattery - is just a sign of cultures mingling and influencing each other, since when is that supposed to be bad? When my son was 13 or 14, he decided that he wanted dreadlocks. Leon was a beautiful boy, but he had and has thin/fine and absolutely straight blondish hair. Still, if he wanted something ... So we did find an African hairdresser for him in one of the not so good parts in town and the hairdresser girls (all of them black) were over the moon that a little white guy would want to have an ethnic hair style. They took ages to get it right on him (probably rightfully wondering why white people have such weird flaccid hair
) and he sat through it with earnest patience. The results were great, looked good on him, started a trend at his school and after a few months ... all the dreadlocks fell off.
Which is what they inevitably do with white people with straight hair as my son then learned.
He was unperturbed, got a crew cut instead and looks back fondly on his dreadlock experiment. Some things you just have to do to get them off your chest.
