Hello,

I have just hooked up my new cintiq 12wx to a macbook pro (late ‘08 model if it matters..).  When I am drawing in sketchbook pro on the cintiq, the eyedropper color selection is off.  If I:

1) quick select blue
2) paint a solid block of blue
3) use eyedropper to select block of blue

sketchbook will give me a nice deep purple color.  All blues come out in various colors of purple.

If I drag my sketchbook screen back over to my mac display and do step 3 again to the same block of blue - it selects the correct color of blue.

I’m at a loss. :(

Please let me know if I need to provide any other information, I’d be happy to.

Hi Nalian,

I’m not getting this problem on my cintiq 21ux.  I’m assuming you are using the ALT hotkey to quick select your colors or have you programmed one of the cintiq express keys?  Is this also happening if you use the Mac native eye dropper (the magnifying glass cursor)?

Try going into your preferences window and toggling off your scroll bar under the CANVAS tab.  Perhaps there is a hidden offset problem here and the eyedropper is picking the wrong area even though it doesn’t appear to be.

I’m using a Mac Pro workstation, but I will try it on one of our Macbook Pros.

Hi Nalian,

From what I gather, the color selection creep is happening on your cintiq but not on your Mac monitor?  It would be interesting to see if the problem also lies with other apps such as Photoshop.  If such is the case, then it does sound like a strange cintiq problem.

...And as usual, when I finally raise my voice, the problem goes away. It’s been happening for a week, but SBP just crashed on me (after trying to use the eyedropper) and when it came back up, everything’s working normally.

How very odd.

I am having this same problem. It is so odd. It happening with both the 12wx and 21ux models when used with my macbook pro. I have tried the 12wx on my PC and on the MBP with Vista in bootcamp and it behave correctly in windows.

Blues slowly turn to magenta if I keep picking the previous color. Once it reachese magenta though it stops shifting, I can accurately pick that magenta. A few other colors shift too, but eventually stop, and its always repeatable the exact same way.

It must be a driver issue reacting to however osx interprets colors, but I’m truly dumbfounded at the logic behind it. If it consistently always picked a slightly off color it would make more sense, but to slowly shift to a certain color and then stop is really weird.

If anyone makes any progress please update. I will update if I figure anything out.

Mini Update: Unlike a previous poster, I also have this problem in photoshop. Same conditions as SBP, it only happens on OS X. This must be a Cintiq driver / OSX issue, and not the fault of the autodesk software.

Photoshop is working fine again.

Changing color profiles affects this problem in Sketchbook. I switched from the Cintiq 12WX profile to Generic RGB and it fixed the problem with the blue slowly morphing to magenta. Unfortunately Green now morphs from to a yellowish green.

I think color profile may be the answer. The rest of the internet seems to think the Cintiq Profile is best, so this problem cant be happening to everyone. Even if the eyedropper worked fine the Cintiq profile makes all blues look purple anyway.

Right now the SMPTE-C profile seems to be working best… Eyedropper seems consistent and blues look like blue.

I also have this problem on my 12wx with SBP 2011 on a new iMac.

Please tell me there is a way to fix this. I love SBP, and want to keep learning it. But not being able to pick up colors will kill my process.

Thanks, everyone.

My workaround is

1) Go into System Preferences, Displays
2) Make the Cintiq the main monitor by dragging the menu bar from the main screen to the Cintiq screen
3) Open up Sketchbook Pro and open your file
4) Make your regular monitor the main monitor again in System Preferences

Voila! Eyedropper works again on the Cintiq. The downside is that now the eyedropper is messed up if you drag your SBP window over to your main monitor, but I get around that by just opening the same file in Photoshop if I need to see it on both my main monitor and the Cintiq.
