The female could possibly be a Mack snow that is now yellowing up. If your mate had her as a hatchling and she was black and white, she's a snow. Both males are tangerines but have too many spots to be called "hypo". Please suggest to your mate that s/he get them off those chips. I once cared for a gecko that dropped its tail because it ingested those chips. Better choices would be paper towel, repti-carpet or ceramic tile.
