My adults look about the same. Many pastel lesser's tend to improve with age and the hypo gene just helps it along. You see similar behavior in a lot of ghost bumble bee's (humble bee's); they don't brown out as the age the way a lot of regular bumble bee's can.
Makes for a heck of an awesome snake. Just vivid!
