The hue of blue known as International Klein Blue (or “IKB”) is a color that cannot be accurately rendered on computer monitors and thus websites as it falls outside the gamut range of color. IKB was created by French artist Yves Klein in the 1950s.

We were recently thinking about this unusual color again while reading Willam Gibson’s recent novel “Zero History” (which we highly recommend). One of the book’s main characters, Humbertus Bigend, always wears custom-made suits that are International Klein Blue. Bigend is the head of a global brand-strategy-marketing-technology-advertising-trend-forecasting-whatever-agency. So that makes sense.
