About
A color profile is a standard to describe uniformly color spaces. In 1993, a group of vendors formed the ICC to define it.
A color profile is data that defines what the color space of a device is, and can be used to convert between different spaces.
The common ones are given names, such as sRGB (or more formally, IEC 61966-2-1).
Color profile data can be written to a file, or embedded directly into an image, which allows a computer to understand what the color values in the image actually mean.
