It would cost you more money but an alternative is a bumblebelly: Pastel Yellowbelly X Spider.





I don't have a pic of an adult so I'm not positive as to how they do with the browning out you mention but I am told the yellowbelly helps them keep more of a yellow color.

NOTE: The snake pictured is not mine. The pics came from a classified ad on KS, I think. I keep a folder with cool pics of combos on my computer for reference.

Good luck,
