Referenzfarbton, or reference color tone, is a predefined color used as a calibration target in color management and quality control. It serves as an objective benchmark for evaluating and aligning color reproduction across devices, materials, and production steps, from printing presses to digital displays and textiles.

In practice, a referenzfarbton can be a physical swatch or a digital target specified in a given color space. The color is measured with instruments such as a spectrophotometer, and adjustments are made to minimize the color difference to the reference, often quantified as Delta E. The aim is reproducibility: when the target is met, subsequent outputs are expected to match the reference within defined tolerances.

Standards and systems support the use of reference colors. In printing, ISO 12647 defines process color targets and tolerances for consistent color reproduction. The Pantone Matching System provides widely used reference colors for brand and product consistency. In digital imaging, ICC profiles link device color spaces with reference color spaces, enabling color management workflows across devices. Color differences are commonly assessed in CIELAB space using metrics such as Delta E and its refinements like CIEDE2000.

Limitations must be considered. Perceived color depends on lighting, viewing conditions, and the observer, and not all reference colors can be reproduced exactly on every device or material due to gamut limitations and aging of materials.

Applications span printing, textiles, plastics, and digital media. The referenzfarbton concept underpins consistent color reproduction across media and over time, supporting brand integrity and quality control.
