Solid Cobalt Blue background details
With hex #0047AB (rgb(0, 71, 171)), this versatile mid-tone blue tone sits around 215° on the color wheel. Its bold, saturated color makes it feel focused and trustworthy, which is why designers reach for cobalt blue when they need a dependable background that still has personality.
Cobalt Blue was born in the kiln
For centuries before it reached screens, cobalt gave glassmakers and ceramicists their most dependable blue — the color survives kiln temperatures that destroy lesser pigments, which is why it stripes antique porcelain from multiple continents. The hex #0047AB keeps that fired-glass intensity: deep, slightly violet, and unmistakably saturated.
Modern use rewards the same boldness. Cobalt Blue is strong enough to hold a full webpage background under white type, vivid enough to make a statement wall, and photogenic enough that fashion editors return to it season after season. It reads as confident rather than corporate, which most dark blues cannot claim.
A palette that works with Cobalt Blue
White gives Cobalt Blue the porcelain treatment, while amber and terracotta play the warm, earthen opposites that make the blue look fired rather than printed.
