Thank you Stephen. I'll add the green. Do not think they were teak, can't see any wood pattern in the photo.
As for the grey. Yes I am aware. Problem with a tan grey as light as this is that it would change greatly with the light at the time. It might have been light grey tan under a neutral 3500K light, but outdoors it would go from anywhere from blue grey to grey to yellowish tan. So it is just a matter of choice IMO.
