Solid Ultramarine background details
With hex #120A8F (rgb(18, 10, 143)), this deep, low-light blue tone sits around 244° on the color wheel. Its bold, saturated color makes it feel focused and trustworthy, which is why designers reach for ultramarine when they need a dependable background that still has personality.
Ultramarine Came From Beyond the Sea
Ground from lapis lazuli carried to Europe from Afghan mines, ultramarine took its name from the Latin for 'beyond the sea,' and the pigment was famously so costly that Renaissance painters often reserved it for the robes of the Virgin Mary. Few named colors arrive with this much art history already attached to them.
The digital version runs deeper than most people expect. At #120A8F it sits close to navy, with a violet undertow that reveals itself next to a true blue. That depth makes it a dramatic full-bleed background: white or gold type on ultramarine instantly borrows some of the pigment's old ecclesiastical gravity, no gilding required.
