Kind of a What if thing but If earth grew under a red sun and we sent a person to live under a yellow sun what would happen to them?

Sunburn, maybe? I'd look up the different wavelengths emitted. I don't think there would be anything like plants becoming inedible.

Haha! Yes! Then there'd be no one to stand in the way of my giant space laser extortion scheme!

Curse you, Superman!
