The problem these "experts" don't realize is that the remake is actually being *very* faithful. Faithful to the way lighting actually works that is. Look at the skybox in the original game. It's an assortment of purples, oranges and yellows, like you'd see at dawn. But if you were to go by the colors of the actual landscape in the original, you'd be pressed to believe it was mid day with a perfect blue sky!
The bright greens and blues simply do not match what the skybox implies in the original, and looks even more jarring in a more modern rendering, and any painter worth their weight would say the same. So either TfB change the color of the skybox to match the original landscape or they update the pallet of the landscape to match the skybox, and seems they chose the latter.
Tldr; this is how lighting actually works, to the dismay of fans.
lol you're talking about artists when artists break the rules all the time. Just because there's a disconnect between the sky color and the grass in a realism sense doesn't mean it's not gorgeous. I don't think anyone gives a hoot about realism when it's a cartoony fantasy aesthetic bud.
