You don't have to add Jungle to make nice Sunglows either. This 3 yr old girl is straight up Kahl, no Lipstick, no Stripe, no Jungle, just Kahl albino and Hypo.
Although I will try for some Lipstick Jungle Sunglows in the future, it's only because I have the genes, and just might get lucky enough to make me one. But it's not a needed ingredient for nice Sunglows.
