Thanks, guys.
TwistedOak, yeah, I feel like I used up all my luck this year, lol.
And, no, the color label is utterly obliterated, but from what I've been able to research, it looks like a yellow green to me, but I've never seen any in person except for this one.
I'm glad to have the label on the back to identify it, but mostly it's kind of irrelevant; this rock will never leave my possession, and will be well used and loved.
