All About Blue
The World's Favorite Color
The Science of Blue
Blue is the color of light between violet and green on the visible spectrum. It has a wavelength between approximately 450 and 495 nanometers.
Blue in History
Ancient civilizations struggled to produce blue dye. Egyptians created the first synthetic blue pigment, now known as Egyptian blue.
Blue in Nature
True blue is relatively rare in nature. The sky and ocean appear blue due to the scattering of light, not because they contain blue pigment.
Blue in Culture
Blue is often associated with depth, stability, trust, loyalty, wisdom, confidence, and intelligence in many cultures around the world.
