Värvuhaldussüsteemide, also known as color management systems, are a set of tools and workflows designed to ensure that colors are reproduced consistently across different devices and media. This is crucial in fields such as graphic design, photography, printing, and digital display manufacturing. The primary goal of a color management system is to achieve predictable and accurate color representation, minimizing discrepancies that can arise from variations in hardware and software.

At its core, a color management system relies on the concept of a device-independent color space. This is typically a standard like CIE XYZ or CIELAB, which defines colors based on human perception rather than the capabilities of a specific device. Each device, such as a monitor, scanner, or printer, is then characterized by its own device-dependent color space. Color management software uses profiles, which are data files describing a device's color characteristics, to translate colors between these different spaces.

The workflow typically begins with profiling the input devices (like scanners or cameras) and output devices (like printers or monitors). This involves capturing color information across a range of tones and hues. Color management software then uses these profiles to perform color transformations, ensuring that a color specified in one device's profile appears as intended when displayed or printed by another device. This process helps to avoid unwanted color shifts, maintaining the artistic intent and technical accuracy of an image or design.
