So, blue has been around for a long time and is here to stay i think. Back in the day it was reserved for Platinum cases (PP and IWC ) but now it sells more watches as a 2nd or 3rd iteration of a model in years after introduction ( Black Bay ) What does seem like a new trend, or revival ( Silberstein ), is the Multi color watch as the Omega Ultraman and Hodxxxx MK40 show. For the new kids or millenials ? whatever that may be. Maybe inspired by the smart watches with colorful display?
