I happened to obtain 2 separate versions of The Quintessential Quintuplets and I noticed in S02E10 when Nino wants to group up with Fuutarou, Nino's eyes are coloured differently...
Question: What's up with this? It's been pointed out to me that 1 is probably an error that was later fixed. But which is the error, and why?
Version 1: Nino's eyes are dark blue.
Version 2: Nino's eyes are baby blue.
I'm guessing it's unlike the 2 versions of Umineko...
In case relevant:
In both versions of the anime, Nino's eyes are baby blue a few seconds later when Nino says 'Stay out of this, Fuu-kun.'
In the coloured manga, Nino's eyes are just dark blue
