let me first say I do not know the original seller from this post and I also have never purchased from him. I’m one of the 4 buyers of C’mongvongng‘s yellow gonis From last month’s post and can attest that his gonis are indeed yellow, neon like a yellow highlighter. That said, you put any neon yellow under blue lights and you should see a greenish tint to it. Not colorblind, not special vision, just blue lights. The problem with the original post is not just green or yellow, I’ll let everyone decide on their own. The problem is that the piece was advertise as something else for much cheaper a few weeks ago, and renamed now to a higher price. Yellow or green, I wouldn’t personally buy from this buyer.
