Hi, I own the medium Diorama in Bleu de Minuit and I love this color, very versatile! With my wardrobe (lots of color during spring/summer and a lot of dark blue, black and grey in the winter) it's absolutely perfect, haven't found an outfit yet that I can't pair with this bag. Blue is definitely my neutral. I also would never describe this bag as navy, in my opinion it's a brighter shade of blue, more a pop of color, it really stands out. I bought this bag just a few days before I went on my holiday to the Côte d'Azur (end of July, early August) and wore it out every single night for dinner and during some daytime trips. No problem at all with my mostly light-colored outfits (white, light blue, yellow, grey). If you are a lover of blue, like I am, this could be the perfect color for you. However, if you find it difficult to incorporate blue in your wardrobe, blue is not your neutral and you should maybe opt for the black. Good luck deciding! And please reveal your purchase with us!
