I will add that in some lighting the iridescent blue cch really glows. I wore my new purple extra mini coco handle to visit my favorite SA, and she showed me the blue. Here I am wearing both, and you can see that the boutique lighting is really showcasing the glow of the iridescent blue caviar.They do look different in person because of the leather. Attaching more pics to help you understand. I love both. I have a suggestion. If u manage to get the blue coco, get it. Dont use it though. Wait for the classic flap to arrive. See which one u like more and return the one u love less .
It seems to me that the iridescent blue mimics the high shine of the iridescent calf minis the most.
