When I was building things and putting them onto the Exchange I built a gondola lot on a lot in Oasis Landing. I put trees and other things from various expansions and store sets/venues. I was surprised about how the colours of the plants in particular changed in Oasis Landing.
Some examples:

I didn't do anything to them to make them these colours. So if you're into a bit of adding some build plants to your sim's home lot in Oasis Landing you could end up with some colours you don't expect to see.
And if your sims collect some dew from the dew plants, and drink it, they might turn an interesting colour for a while

Some of the dew plants (very large flowers that come with Into the Future) I think I had the lot placed in Aurora Skies for this screen shot. The plants resumed their normal colours in that world.

Have fun.
