Cobalt Blue #0047AB

Cobalt compounds have colored glass and ceramics for a very long time. Chinese blue-and-white porcelain got its blue from cobalt, and the look was copied across Europe, most famously in Dutch Delftware. The pure pigment known as cobalt blue was developed in France in the early nineteenth century and became a favorite of painters.

Because of that history, cobalt suggests craft and quality. It looks like a blue someone chose on purpose. Hand-painted tiles in Portugal, Morocco, and Mexico often use similar deep blues, which gives the color a warm, handmade association despite being cool.

In modern use it reads as confident and clean. It has the trust signals of blue in general but more drama, so it suits brands and products that want to look bold without leaning on warm colors like red.

White text reads well on cobalt blue, so it works for primary buttons, banners, and bold social tiles. Black text is a poor match. On screens, cobalt holds attention without looking as raw as pure #0000FF.

In fashion it is a classic statement color for coats, bags, and suits, especially beside camel or white. Interiors use it on tiles, glassware, and accent cabinetry, often against white walls. It can lose definition next to black and clash with deep purples, so keep those apart.
