Compare this to Adams pic above, this is a Graziani line pastel. Notice the distinct change from the bright yellow down low to the more brownish yellow up top. Then check Peter Kahl's website www.pkreptiles.com, and look at the adult male Graziani line he has. You can see how they change over time. I don't know if this is true of all Graziani line pastels, but I do see some adults (from various lines) that look like the one on Peters site. I will be curious to see how Blaze here changes (or does not change) over time. I think one Adam has will always glow like light bulb!!!! ;)
