Gah! You're too white and bright! But yeah, even a clear sky seems to give my eyes problems until late afternoon. It's just... Too bright I can look at the ground or a white truck just fine, but the sky? Nope!

I want the sky to always be dark enough to require artificial light.

So plant life dies off.
