Lots and lots of google searches actually. And just luck of the draw. The green is a really dark and green on the majority of the Nurv, but the body is a lighter green as you can notice and you can probably see some of the anno flaws toward the front and back of the body. Which is sad because the Nurv is such a nice marker. I'll just have to scuff it up playing though.
I got a pair for my Darq at the same time. Oddly enough I ended up with an Evil Ernie theme going with these markers without really thinking as I wanted something for my Darq first because I was sick of the tadao yakuza grip and how they looked because everybody would have them. I just thought it was funny how I got Lady Death and then Evil Ernie without really thinking about it. They came out really nice too.
