Many thanks for your reply and for analyzing the issue, Hans. I know this is a compromise solution. Of course, I cannot expect from ConTeXt to assign the right profile to the image. The user is the one that might mess the final PDF document by selecting the wrong color profile for \externalfigure. But this possibility is already there with the profile key in \setupbackend. Choosing the right profiles is up to the user. Wrong attribution causes unvalid documents, but attribution is a user task. Explaining this information in the wiki is essential to clarify that “feature”. (I can do that myself.) Having this in mind, could you reconsider the implementation of the profile key implemented for \externalfigure?
