maybe people finally produce more high quality pastel, and better lines like citrus pastel, lemon pastel or blonde pastel are getting mixed in all the time?

it being a superb pastel doesnt change that there most likely isnt another gene involved, if you manage to produce more like these you will be the one selling them for 50 dollars, contributing to the nice-pastels-for-50-bucks segment of the market.

most likely whats causing this is really simple: breed a superb pastel, hatch a superb pastel. what else do you expect to find out?
