Any axanthic mutation will still let a small amount of yellow through. (Ever seen a snow without any yellow at all? I think people were speculating that this may have to do with where the xanthophores congregate in the skin and that each line of axanthic may only affect certain layers.) Anyway, with less of that yellow coming in from the non-axanthic parents, you should eventually start seeing more silvery babies after a few generations. Also, in my experience, it seems that lighter axanthics hold their colour better as they mature, and darker ones tend to get more brown.
I figured it would be the same as how albinos work - in which the lightness can affect how high in contrast the albino is.
thanks for clearing this up
