Small, random questions about RotE that still bother you (spoilers all RotE books)

[Sylve]

Hello! I recently finished the RWC and I've been wondering for a while about some inconsistency between the Livetrader books and the Rain Wild Chronicles. More specifically:

1) I think I remember Malta's hair being dark brown/black, like all the Vestrits. Yet in City of Dragons, Reyn mentions "the gold in her hair". So I blamed it on the elderling changes, maybe there were gold streaks among the black. But then in Blood of Dragons they clearly described her hair as gold, which left me confused. Did her changes include her hair colour?

2) Tintaglia's color. In Ship of Destiny she is described as blue, yet when light changes she could as well be silver. Sintara however is described as azure blue. Yet in Blood of Dragons (I don't have the page, it's near the end somewhere) they describe Tintaglia as "blue as the sky". So either they know a different sky than I do, or we confused some dragons here?

3) Sylve's eyes were in Dragon Keeper described as "Her eyes were coppery brown, probably on the turn tu pure copper", though in Dragon Haven, Sedric observes "The light caught briefly in her eyes as she did so, showing him a pale blue gleam." Again, it was right after Mercor began changing her, so it could be blamed on the changes.

They're minor things, I know, but they've been bugging me, so I came to this thread. I briefly browsed the other threads, I don't think any of these possible inconsistencies have been mentioned anywhere before.
If you can enlighten me, thanks in advance!
