Discussion
Colors in a device-dependent color space are not transformed or otherwise modified when displayed on an output device—that is, there is no attempt to maintain the visual appearance of a color. As a consequence, colors in a device color space often appear different when displayed on different output devices. For this reason, device color spaces are not recommended when color preservation is important.
