Which Zoysia is the darkest green?

As a keen gardener and lover of all things green, I'm curious to know which variety of Zoysia grass boasts the darkest shade of green. Is there a specific cultivar that stands out for its rich, lush hue, or does the darkness of its color depend on environmental factors such as soil quality and sunlight exposure? I'm eager to learn more about this fascinating aspect of Zoysia grass and how to cultivate the darkest green blades possible.
