History of NERD's lemon pastel?

So for a long time I've really been wanting a NERD lemon pastel. Most seem to have a beautiful contrast and seem to be the brightest pastels out there. Most people say a pastel is a pastel and it all depends on the individual (which I somewhat agree with), however many examples of the lemons are striking. My question is, does anyone know the history of NERD's lemon pastels? I was doing some reading on Graziani's site and he talks about how his "jungle pastel" line began and that at the time, Kevin from NERD had a pastel from captive-hatched origin that looked just like his that he was also selling under the same name. What I'm wondering is, does anyone know if the lemon line originated from a different animal or is it the same line? I know that Graziani pastels and lemon pastels both seem to share certain characteristics, which is why I'm curious about their history. I'm needing some of you well seasoned ball python breeders to chime in...:snake:

I don't know any of the history but I went today and compared my normal pastel to a lemon for sale and the lemon is definitely a lot sharper looking!
