There are a lot of colors to choose from with the Cutpile carpet, including eight or so different greens. (Be sure to expand the list.) There is one called Sage Green that might be close to what you’re looking for.
The Essex (premium) material is more limited in colors, but the Cutpile will be similar to factory. (Essex is more what you would expect to see in a Cadillac.)
Add the mass backing option if you can afford it. It significantly cuts down on noise and heat transfer through the tub.
I don't know if this thread ever ended but I actually have almost new Sahara carpet I took out at like 40 or 50,000 miles it looks fantastic original color definitely if you'd like to see it
