Not sure why you're down-voted - that was my initial reaction too. Especially the "aurora" palette seems at odds with the name. Add a red and a purple to the "frost"-palette, and you might at least call it "aurora" with a straight face. That said, I'm not sure pastels like these would ever capture an "artic" feel.

Overall, apart from the lack of contrast, they're not half-bad. But the naming doesn't seem to reflect the colors - it seems rather arbitrary.
