Pearl is a very popular color right now.
The Pros:
Reflects underwater lighting in dramatic fashion
Looks very contemporary
Is non-porous and cleans easily
The Cons:
Will scratch (small scratches can sometimes be buffed out)
Will show damage if struck by heavy objects (falling tree limbs, etc) as will most shells
Reflects tremendous glare during daylight hours
Will show water spots more than a Quarite or Endurol shell
