I need to make icing that looks like the color of real grass, not leaf green. Can anyone tell me what colors I add to leaf green to get the color of real grass?

I always use moss green to make grass.

I made grass for a baseball cake I just did & I added navy blue & yellow to the leaf green to get the color I wanted...you can take a look at it in my photos & see if thats the color you were going for.
