That's a pretty good, and probably possible, theory you have there, Lyra.

Still, her mane and tail are only pink in the anicent artwork of her and Luna from both the series pilot, and when we see them as Scorpan asks for their help to stop his forsaken brother.

My theory is that her mane and tail were their multicolored state since birth, and both her and Luna's manes and tails gained their sparkling and flowing motion when they first gained their Cutie Marks. Before that, their manes and tails were as normal as any pony else's, like how we saw them after they transferred their Alicorn magic to Twilight in the Season 4 finale.
