Blue pigment

Blue pigment refers to a substance that imparts a blue color to materials, created through various chemical processes. Historically, natural blue pigments like ultramarine and cobalt blue have been prized for their vibrant hue and stability. Modern synthetic blue pigments, such as phthalocyanine blue, are widely used in paints, inks, and textiles due to their durability and intense color. These pigments work by absorbing specific wavelengths of light and reflecting blue light, which our eyes perceive. They are an essential component in art, manufacturing, and design, providing an enduring and vivid blue color.
