I'm still not positive either way.
I've seen really yellow normals before that looked remarkably like her, but I've also seen some pastels, what I consider low quality, that look like her.
The only hesitation I have is most low quality pastels at her age have a lot of orange to them, I don't think I've seen a browned out pastel her size that had no orange. That is another thing that makes me lean more towards normal. For her markings to be that browned out I mean, she should have more of an orange base color to her markings, not yellow. If she were bigger and older I'd say browned out pastel, but as young and small as she is, I just don't remember seeing a pastel that brown that didn't also carry the orange color to the markings.
I guess you'll just have to wait and see how she grows. Perhaps as she gets bigger, she'll change and make it easier to tell.
