At first I was like "why is there yellow in her hair?" and then I realized I was silly and that was clearly her crown! It looks great. I'd love to see it with more pastel-y colors if they were available (especially the orange on the cutie mark) but I know finding absolutely perfect fabric colors can always be a huge challenge and these ones work really well together even if they are a bit more vibrant than the colors used in the show.
Yeah that makes total sense. I imagine pastel pink would be easy to find, but pastel orange for the cutie mark seems like it would be rather uncommon and it would look silly to have some pastels and some not!
