I agree with what everyone said, although the lemon line tends to be brighter as babies (although I have seen some very brown lemons), all pastels will brown out to some degree. Here is my regular plain old pastel, he's a 2010 and pushing 500 grams. He's still quite pretty in my eyes


Not sure where you heard any single gene pastels got brighter as they get older, you may be thinking of fireflies (fire pastels), I know they get brighter as they age.
