Farbwert

Farbwert, literally color value, is the numeric representation of a color in a color model used in digital media, design, and color science. It encodes color information as numbers, enabling precise storage, processing, and reproduction.

In common digital systems, Farbwerte appear as components in color models. In RGB, a color value is a set of three channel values (red, green, blue) that define the color, often with an alpha channel for transparency (RGBA). In many file formats and user interfaces these channels are stored as 8-bit integers in the range 0–255, or as floating-point values in 0–1. Hex notation (#RRGGBB) is a compact representation of RGB. In printing, CMYK uses cyan, magenta, yellow, and black color values.

Colors can also be represented in perceptual models such as HSL or HSV, which separate hue, saturation, and lightness/value. While RGB describes how colors are produced on a display, perceptual spaces aim to match human perception more closely. Color management involves converting Farbwerte between spaces to maintain visual consistency across devices, using profiles like ICC and transformation pipelines.

Grayscale Farbwerte reduce to a single luminance value. In digital images, each pixel stores its Farbwert in a certain bit depth, commonly 8 bits per channel, but higher depths are used in professional workflows.

Example: red as RGB (255, 0, 0), hex #FF0000, CMYK (0%, 100%, 100%, 0%), HSL (0°, 100%, 50%). Farbwerte are central to digital color specification, comparison, and rendering across software and hardware.
