9.1 and colour

Hi I just upgraded to 9.1 the other week and (amongst various issues) I have noticed that colour rendering in preview is different to c1 (seems greener in preview)

working on macbook pro, el capitan 10.11.3

proof profile is set to selected recipe which outputs in adobe rgb 1998 (jpgs)

rendering intent in preferences is perceptual.

changing the default processing engine in preferences makes no difference

Could anyone please help or is anyone else experiencing this?

Many thanks

  Does it make any difference if you set the output recipe to use sRGB rather than Adobe RGB?
  
  (I appreciate that you may want to output in Adobe RGB, but it could be that Preview displays that differently from how it displays sRGB. It would be worth experimenting to find out.)

  Thanks for your help ian.
  
  i tried your suggestion, unfortunately it didn't solve the problem - both files do not match appearance in c1.
  
  The srgb does look ever so slightly better, super sutble , but presumably some slight gamut clipping is happening that is causing the slight difference.

  I'm not a Mac user so maybe this is a silly question, but what do you compare the preview in C1 with? Which viewer, and can it handle profiles, and especially Adobe? (it might possibly be a problem of your viewer not of C1)

  Sorry to ask, but is your monitor profiled? [Edit: my apologies, I meant calibrated]
  
  I am not on 9.1 yet, still on 9.0.3 but coming from Lr, one of the biggest learning curves has been that if I am editing for sRGB I might actually need a clone variant of ProPhoto RGB, Adobe RGB or any of the profiles for the papers I use. This does not happen with all the photographs but it happens sufficiently often. I am assuming that you are aware of this and this is not your problem.

  Hello, just thought it might be useful to follow this up for other users.
  
  I screengrabbed a file that showed an image in c1 and the same image in preview side by side on the same screen where the colour difference was apparent.
  
  I then imported the screengrab onto a different mac and opened in photoshop. When increasing the saturation to 80% it confirmed what my eyes suspected that there was a definite colour difference between the programs.
  
  However C1, based on RGB values of an object i knew to be neutral (white colourama and a grey card) was correct.
  
  Apple's Preview was a little blue/cyan.
  
  So it seems the problem was Preview not Capture One
  
  This might be related to the problem, another user on the apple forum.
