But, if it's done right meaning if it uses a color distance-algorithm it may work even though the colors are distorted, the algorithm will check if the color is within a given range of tolerance, this may require a different color space than RGB, often used is LAB, or HSB.
Though color management software, such as that built into image editing applications, will pick the closest in-gamut approximation, changing lightness, chroma, and sometimes hue in the process, author Dan Margulis claims that this access to imaginary colors is useful, going between several steps in the manipulation of a picture.
