I think lightings in pics can be misleading. Here is a pic of my gen K series 2018 ROO rotor. It is yellow gold and the case is rose gold. I do not think there is a difference between the 15400 rotor and the ROO one.
But whatever gold you call it, there is a marked visual difference between the gen rotor tone and the rep one. I have seen enough side by side to ascertain that.
It is a difference you need to see in person side by side to understand. Pics taken from the net will not necessarily tell the true story but your eyes will never lie. My personal preference is in fact for the rotor of the gens to be rose gold (like the tone of the rep).
I will be the first one to be happy if what you say is true. But of my 10+ AP gens, none of them have a rose gold rotor. 3 of them are 2018 pieces. I have the actual products in hand to compare. But I will be happy if what you say is true!
Maybe
mech500 can chime in. He owns the 2018 15400 gen if I recall. I am 100% the color of the rotors differ between rep and gen no matter what color gold you call it.
I also agree with you that the 2018 blue dial is gorgeous and I hope that the rep blue dial color can be updated too.
If wishes were fishes. Lol
