device color standards?

    right now there are at least two ICC device color standards, whereas the
    purpose of ICC was device independent color
    http://www.color.org

    there is sRGB which is a CRT monitor color space
    http://en.wikipedia.org/wiki/Srgb

    there is ProPhotoRGB which is a hybrid output film color space
    http://en.wikipedia.org/wiki/ProPhoto_RGB

    ProPhotoRGB was probably a response by Kodak to Hewlett Packard and
    Microsoft's input of sRGB to the ICC

    you could probably add SWOP to this list I think
    http://en.wikipedia.org/wiki/Specifications_for_Web_Offset_Publications

    an oncoming problem with sRGB is that there is no CRT output standard
    any more. There is LCD, LED, Plasma, OLED, projectors, etc.

    the device standard must switch to the input as opposed to the output,
    if you want a device standard, use a camera sensitivity standard

    such a standard would either have to be a compromise of output standards
    listed above, or a CIE device independent standard, the eye, so after 20
    years ICC is back to the beginning

    sRGB seems to have led to advancements in scene balance and appearance
    modeling, attractive color, which is the preference in most markets, so
    some good has come of this

    then there is "good enough" color as opposed to the education neccesary
    for accurate color

    but some markets do need accurate color and digital color managed
    workflows have not taken hold here according to the ICC, I think
    commercial photo labs and commercial prepress labs fall in this category
