No (When I turn ICC profiles on I in "Document settings--colour 
management" I see this option in "Save as PDF--Colour". I suppose the 
best is to turn it on (I see just one profile installed, I suppose this 
is the standard Scribus profile? It is named "sRGB IEC61966-2.1"

I see ..., bad choice, technically :-(

I have tried now with the standard options and Colour management on.
The resulting file is here:

I have also put up my cmyk picture for the case that someone wants to 
have a look:

(NB: almost 50mb big)

But I can't say I spot any difference in acrobat reader between what I 
had without icc-profiles and what I get with ...


Thanks for all help!
