That's definitely a pastel, but it's not a particularly bright specimen. Really, "bright" rarely applies when talking about single-gene pastels, although I have seen some rare individuals who maintain some brighter coloration. Pastels run the gamut from moderately yellow to almost plain brown of varying shades. It's quite possible for a "normal" to look lighter than your pastel. As babies, they are a lot more colorful and that is where the term "pastel" comes from....it's more reflective of their baby colors than how they usually look as mature animals.
