Väriavaruusprofiili, often referred to as color profile, is a set of data that describes the color characteristics of a device or a medium. It essentially defines how colors are represented and reproduced. In digital imaging, color profiles are crucial for ensuring color consistency across different devices, such as monitors, printers, and scanners. Without proper color profiles, the colors you see on your screen might not match the colors printed on paper or displayed on another device.

A color profile typically contains information about the device's gamut, which is the range of colors it can display or reproduce. It also includes data on the device's white point and tone reproduction curves. This information allows software to convert colors from one color space to another accurately. For example, when you send an image from your computer to a printer, the software uses the color profile of your monitor and the printer to perform the necessary color transformations.

The International Color Consortium (ICC) has established standards for color profiles, often referred to as ICC profiles. These profiles are widely used in the industry to facilitate color management. Applications like Adobe Photoshop and many operating systems support ICC profiles, enabling users to manage and apply them to their workflows. Understanding and utilizing color profiles is essential for professionals and hobbyists who require accurate and predictable color reproduction.
