yea that's normal for a leo to change colors after each shed when they are younger...they are born with bland yellow striping over a dark pigminted skin usually (unless bred to be a certain morph or an albino or whatnot)...after a few shed's they'll start loosing there juvenile skin pigments and you'll eventually see what morph they will grow to be...in young leo's it's hard to tell what morph they are...usually around 6-7 months you can be pretty confidant in what morph they are...expect a few more color alterations while he/she's growing up...nice leo btw ;]
i'm still not familiar with morphing quite yet...so i'm not even going to mislead you with a guess...good luck with him/her ;D
