is it possible to tweak the colours/lighting model?

Hello,

i'm playing my first game of Ele:FE. While overall, it seems like a nice improvement on the earlier game, I find that the changes to the lighting model/colours have gone a little bit too far. Everything feels a little over-saturated. Is it possible/easy to turn this down a little? I find current set up strains my eyes a little and it can be difficult to make out some of the unit model details

I think somewhere half way between the old and new set-up would be ideal. 

Thanks
