CIE Standard Illuminants

CIE Standard Illuminants are carefully defined light sources used in color science to ensure consistent color measurement and comparison. They mimic various real-world lighting conditions, like daylight or indoor lighting, allowing manufacturers and scientists to accurately evaluate how colors appear under different lights. These standard illuminants serve as reference points, ensuring that color specifications are uniform across industries and applications, facilitating reliable color matching and communication. They are crucial in fields like printing, textiles, and display manufacturing, where consistent color appearance under different lighting conditions is essential.
