Solid Blue background details
With hex #0000FF (rgb(0, 0, 255)), this versatile mid-tone blue tone sits around 240° on the color wheel. Its bold, saturated color makes it feel focused and trustworthy, which is why designers reach for blue when they need a dependable background that still has personality.
Blue, the world’s favorite color
Ask people their favorite color and blue wins in nearly every country surveyed — usually around four in ten answers. That universality is why banks, airlines, and social networks default to it: blue reads as competence and calm in almost every culture, with none of red’s aggression or yellow’s alarm.
Blue pigment was historically precious — ultramarine was ground from lapis lazuli and cost more than gold, reserved for Madonnas’ robes. Remarkably, the hunt never ended: YInMn Blue, discovered by accident at Oregon State University in 2009, was the first new inorganic blue pigment in over two centuries.
Pure #0000FF is intense for large areas, which is why most “blue” brands actually ship softer or darker variants. Use the adjustment sliders above to pull lightness down for a calmer backdrop, or browse the blue collection for ready-made alternatives.
