Are you looking for stem plants or just any type of plant? I have lots of rotala that is a light shade of green with some pink, though the pink may disappear in your tank if it is lower light and be a nice green color, unfortunately, I have no way to give you a picture as I have no computer atm.
Crypts would be good as they come in many different shades, sadly I have none...
