There are many shades and applications of Fireglo, from very dark around the edges to very light orange, from nice gradual burst to clownburst like early 90's.
In this specimen the front is more faded than the back, and this is telling me that this bass spent large portions of its life on a wall hanger (or a stand) and not in a case. Refins are usually the same shade front and back.
The edges in S models are not rounded like Fenders, so when they wear with use they look like this.
