green, like lounge green

Or turqoise like reflecting pool

Green and gray usually go together; I would check paint chips at the store, next to your phone? pic of the siding. Maybe take a close up of just the siding to check if you're planning on buying that day, better would be to bring chips or samples home to see in person, it's less likely to make a mistake that way seeing it in place.

The iron ore would be great and then some nice rectanglar black planters along the edge of the deck.
