A värvihaldussüsteem, or color management system, is a set of tools and processes used to ensure consistent color reproduction across different devices and media. In essence, it aims to achieve the goal of "what you see on your screen is what you get when you print." This is crucial in industries where color accuracy is paramount, such as graphic design, photography, printing, and video production.

The core of a color management system relies on the concept of color profiles. A color profile is a file that describes the color capabilities of a specific device, such as a monitor, scanner, or printer. These profiles contain information about the device's gamut, which is the range of colors it can reproduce. By using these profiles, a color management system can translate colors from one device's space to another, ensuring that the intended colors are displayed or printed as accurately as possible.

Key components of a color management system include color spaces, device profiles (ICC profiles are the most common standard), and a profile connection space (PCS). The PCS acts as an intermediary, allowing for the conversion of colors between different device profiles. Calibration and profiling are essential steps in establishing accurate color management. Calibration involves adjusting a device to a known standard, while profiling involves creating the color profile for that calibrated device. Without proper calibration and profiling, a color management system cannot function effectively, leading to color shifts and inconsistencies. The ultimate aim is to minimize "out-of-gamut" colors, which are colors that a device cannot reproduce, and to manage them gracefully.
