There are three most common color spaces: sRGB, Adobe RGB and ProPhoto RGB.
I am being asked quite frequently “what color space should be used” and “why not just use the biggest”? The answer to this question is not as straightforward as one might hope it would be, and it largely depends on photographer’s preferences, workflow and mode of image distribution. The larger the space the more of a range the image can potentially portray. These spaces are responsible for a range of tone and color the image produces. Once you start working with images you will quickly encounter different options for working color spaces.
