One interesting thing about Leopard Geckos is that their pattern changes as they grow from baby to adult. On our gecko Waffle, the white band she had around her neck has just recently changed with her last shed (she has shed twice in the last 5 weeks).
In this photo taken a week ago she appears very orange and the band on her head is white with a bit of orange speckles and dark speckles. That is not a trick of the light it is really how much she changed. Her little tongue can be seen below, the pink spot on the end of her nose.
Here she is just a week later after a shed and her neck has faded about 50% away on her neck and her body suddenly looks more yellow. Her little legs are suddenly less orange and more yellow as well. It will be fun to see how she changes as she grows.
