Has someone implemented the above mentioned concept of colour indicator (http://cv.iptc.org/newscodes/colourindicator/) or has realised a similar concept in PSu?
IMHO it would be very easy if a label "Colour Indicator" (values: coloured, bw, greyscale, color-key...) could be version-specific - which is not possible in PSU; but what to do then?
Ideas are very welcome!
