Hi! So first I wanna suggest to improve foliage in this game why? Well for starters ghillie suit doesn't blend well compared to the alphas.
The bushes these days are on 2d models when you're 20 meters away from them even pubg mobile with its less impressive graphics (at least for me) has better foliage.
Secondly, I still don't get how the past orangey colour causes eye fatigue. Personally, the current graphics hurts my eyes not the colour but with how the lights adjusts I think it's called exposure (this does not apply to light graphics). So maybe fix this? Or just do some tweaking on it. Also, I wanna suggest making the orange colour from the alphas a filter. Yes, someone else suggested this and I fully agree.
