@InfiniteVerve... As @jpkarlsen points out, in this game you must have the same conditions to make a comparison. I've become painfully aware of this when loading a lot to the gallery. Location, season, weather condition, time of day, and sometimes 'world', all make significant differences in the lighting (and hue). Hopefully you will find when the pack releases that the world will not have a tint issue for you, and that it's one of those factors (or a combination), or some of the Game Changers' screen settings (don't get me started on that one), that was causing this appearance when you watched them.
We've had worlds with a 'cast' for a gameplay reason (Evergreen Harbor, StrangerVille). I also just popped into Forgotten Hollow - where I never play - and it seems a bit different, and Brindleton Bay has always seemed a bit saturated to me. But that makes gameplay sense. Brindleton Bay is rainy and somewhat lush. Sulani is also quite lush and colorful. That all makes sense.
Personally, I would love if the world is a bit saturated to emphasize the plant health and English countryside feel (since they have a fair amount of rain, which most plants love and flourish in). However, if there is a hue to the new world that ends up bothering players, especially strongly, I expect this will end up addressed in a patch, as others have said here. I hope it will only be a bit saturated (not an issue) rather than tinted, and that you will enjoy it a great deal! 🙌
