That top color you posted is not "Shadow Grass" it's called "Cottonwood" and is a gloss target finish that is supposed to resemble a wood grain finish.

I have a Firestorm Gray bow myself and both it and the Cottonwood have a gloss clearcoat which I would imagine if hit at the right angle by sunlight would shine like heck.

If you are interested in something that resembles "Shadow Grass" thengo with Advantage "Max4" that is a waterfowl sort of pattern with marsh grass and a good deal of contrast.
It's actually probably my favorite of the camo finishes.
