The two colours are sometimes confused both here on FPN and elsewhere. Yes, I sometimes get a bee in my bonnet but in years to come it could be of assistance to someone. After all many still get confused with the correct terms for Ripples, Wood effects and Striats. So, there is a Caviar and there is a Blue. There is no Blue Caviar or Caviar Blue. Caviar is after all a browny/black product...not blue black. I present the Waterman evidence. I rest my case.
