    File exchange with other users
    For the file exchange with other users, the profile for the RGB working color space should have                sRGB
    as smaller file size as possible, so that the size of the image file hardly changes after embedding
    the profile. Furthermore, it is advantageous if the users who exchange digital image data agree on
    possible one single RGB working color space.

    No parameters or references from the ICC for RGB working color spaces
    Many users embed profiles in RGB images as a matter of course and also apply them when opening.
    Despite this, there is still a lot of RGB data in circulation without a profile, mainly for office and
    internet applications.

    In the ICC specifications there are no references for RGB working color spaces or even parameters
                                                                                                                   AdobeRGB
    for which color space should be used if no profile is embedded. Accordingly there is an uncontrolled
    growth of references from various organizations and a wide range of settings in application programs.
    This results in difficult situations, as the next sections show, where even many color management
    professionals are left in the dark.

    Fault tolerance
    It can always occur that in a color management workflow the RGB working color space has not
    been embedded in the files, or that the receiver does not extract the embedded working color space.
    In both cases a color shift occurs when the files are opened. The more different the working color
    spaces are between the sender and receiver of the data, the greater the resulting color shift is. If the
    sender and receiver coincidentally work in the same or a very similar working color space, the effect          ECI-RGB
    will be less dramatic.

          To avoid such problems from the start, it is imperative in the use of RGB data to embed
          ICC profiles in the image data when saving. And the application programs must be so
          configured that embedded profiles in RGB images are automatically extracted. In the area
          of office and internet applications, many application programs and browsers are,
          however, not able to incorporate embedded profiles correctly.

    sRGB, AdobeRGB, ECI-RGB
    According to the references of branch organizations as well as the defaults in application programs,
    the most prevalent RGB working color spaces are sRGB, AdobeRGB and ECI-RGB. The particular
