Farbmessgrößen

Farbmessgrößen are quantifiable metrics used to describe and measure color. They provide an objective basis for color specification, enabling consistent reproduction and comparison across different devices, materials, and lighting conditions. The primary goal of Farbmessgrößen is to translate the subjective perception of color into objective numerical data.

Several systems exist for representing Farbmessgrößen. The most common approach involves three-dimensional color spaces, where color is defined by its position along axes representing different color attributes. Key Farbmessgrößen include those related to lightness, hue, and saturation. Lightness, often represented by a value like L*, indicates how bright or dark a color is. Hue, typically represented by an angle such as h, describes the pure color itself, like red, green, or blue. Saturation, denoted by C* or s, quantifies the intensity or vividness of the color, distinguishing a pure color from a gray of the same lightness.

These Farbmessgrößen are typically derived from tristimulus values (X, Y, Z) which are obtained by measuring the spectral power distribution of a light source or reflected light and then applying color matching functions that simulate human color perception. From these tristimulus values, various color models like CIE L*a*b* and CIE L*C*h* can be calculated, providing standardized ways to express color numerically. Farbmessgrößen are crucial in industries such as printing, textiles, paints, and digital imaging for quality control, color formulation, and communication.
