Looking at the bill, they're 35% tinted even if they look and might be lighter. I don't know if you have Jason's Dita lenses but I'd say they're the same color, just a shade or two darker. I don't have a color code or else as I picked them from the ones my optician already had.
Again, the champagne of the frame is barely noticeable when worn, as for the size, yes, the NDG's are only in 50mm, which is kind of small, even for me. If you have a large head, you can try them but they're not gonna be comfy, and you'd rather want to go with the OP Lachman, quite similar and available in 53mm. I'm here if you need anything else
