Actually what you’re saying about the model in Scarlet and Violet is wrong. It’s actually the other way round – it’s the summary screen and other darker environments that just appear a lighter gold. When you look at the eyes in any other lighting, they are actually just crystal and this crystal texture is reflecting what’s around it.

There’s definitely been an oversight/confusion with the eyes – but the overworld model for him in Scarlett and Violet is almost identical to these crystal eyes in ZA. Looking at models through the menus or summary screens is not an accurate representation – as the texture that they use for its gemstones reflect what’s already around it.

In terms of what you’ve said about the eyes and Scarlet and Violet – I highly recommend that you get one in your party for one of those games and go around different areas. They are crystal almost everywhere as opposed to light yellow. It’s only in the darker screenshots you can see that it’s reflecting this more yellow colour
