Hermes Picotin Lock 22 CM Bag Handmade In Taurillon Clemence Leather Silver Hardware 7P Bleu De Prusse

Bleu de Prusse is the blue that hides in plain sight: a dark, green-tinged blue that most people will call black until they are standing next to you in daylight. I like carrying a secret, and this bag is one.

The green undertone gives the Clemence grain something to catch, and in bright weather the whole bag shifts from ink to pine. The unlined bucket takes a day’s load without ceremony: wallet, phone, keys, glasses case and a folded umbrella, with the soft sides breathing around it all, and the open mouth makes reaching in a one-glance job. Under office lighting it is the most composed blue in the room.

Silver hardware is the correct match here; against this blue it reads almost pewter, and the lock sits flat on its tab rather than hanging as a decorative afterthought. The handles are plain, short and firm, and they fold toward each other when the bag is put down, keeping the silhouette narrow. In winter it sits almost navy under warm lamps; in summer it flashes green along the fold lines, a flicker that keeps it from being just another dark bag.

That undertone is the detail that makes it interesting and the one that makes matching worth a thought: this blue prefers charcoal, olive, cream and camel, and it merely tolerates bright white. In low light it simply reads black, so if you want a bag that announces its blue, this one keeps the secret to itself.
