Champagnes will vary wildly when another gene is added. their colors, pattern maybe added (as with Enchi for example), shading, etc. will all vary across the board. and then there's the Champagnes with ringers which will also vary in size.
my Black Pastel Champagne het Ghost girl is still a sub-adult. she's orangey-pink with dark shading and little ringers. she was produced by Bigfish1975 of Porter's Pythons. her dad is more golden and has a huge ringer - looks like a Pied. his pix are posted here on the boards. maybe Mike and Dave Green, who's also big into Champagnes - probably the Champagne King, will pop in and share some of their pix.
