📜 Origin & History

Ink Blue draws inspiration from the way liquid ink spreads on Xuan paper. In China, literati produced ink from pine soot or oil soot, with colors ranging from black with purplish to greenish undertones. As the saying goes: 'Ink manifests five colors' — its base hue is ink blue.

In Ukiyo-e, ink blue was known as 'blue ink.' Hokusai, in his Thirty-six Views of Mount Fuji, extensively layered Prussian blue with ink to create profound oceans and night skies. This palette later inspired Van Gogh.

In the industrial age, dark inks represented permanence and inalterability in archival records. Typewriter and printer ribbons were also often deep blue-black. This bureaucratic tradition established ink blue as a subconscious symbol of officialdom and sanctity.

In 21st-century digital design, pure black (#000000) is considered too harsh. Ink blue, as an elegant alternative to black, delivers pixel-level depth on OLED screens while maintaining softer visual transitions, making it a favorite for dark mode interfaces.
