Color problem

Hi there,

I've encounter a color problem with my mac. First I saw it in photoshop when doing some tutorials and using quick time to play tutorial movies and working with included files simultaneously. What should be blue like 0 red 0 green 255 blue is actually violet on my mac. It was strange because I saw a nice blue sky on a quick time tutorial movie and the same sky on file I was working on it was actually violet instead of blue. It was so strange to me then I've started to look for the answer and i appears the when I choose 255 blue and o red and green in photoshop color picker it's violet instead of blue. I thought it was sth wrong with photoshop but when I run color sync utility and choose calculator (generic RGB profile) and put rgb values 0 red 0 green 1 blue its also violet.

Could any one tell me why this is happening and what's going on with my blue ???

Important thing I using Eye One Display 2 for screen calibration

I'm not an expert then it comes to color management and hove no idea about color sync utility. I'm just a young photographer, retoucher and designer who wants to have good accurate colors and spend whole his time on creative work not on fighting with some color management problems.

Please help.....

Well, I've done some tests . Tried another Eye One Display - results were the same, also used main with EIZO CG222W and everything was Ok. Conclusions: probably Eye One Display 2 is not compatible with new LED Macbooks. BTW there is a funny thing about connection external LCD to Macbook Pro. As far as I know EIZO has inside monitor calibration and it does nothing with video card actually puts it to 0. Here is a problem. When You attach additional LCD to macbook put macbook to sleep and wake it up only with external LCD turned on i will somehow send this sam profile color info from default laptop LCD profile to external LDC so colors become oversaturated. The solution is to restart OSX with only external LCD turned on so it will load profile settings for video card from external LCD profile. The goy who lend me his Eye One and EIZO LCD told me about this issue. He was fighting with it for over a month with no help from both Apple, X-rite and EIZO. Finally he solve this problem in the way I've just written above and EIZO admitted that it's their fault and they will do something with it with next firmware or software update.

I wander if there is a chance that Spider 3 Elite will work better with my MBP. Maybe the better option is to stat to collect money for external LCD.

Now is a question - which one to take:

EIZO CG 222 W
EIZO CE 210 W
EIZO CE 240 W (I heard that EIZO 24" LCDs have some problems with lighting on the sides)
EIZO CG 210 N-K

Maybe some other brand? What are the main differences between this LCDs?

I need this LCD mainly for photography editing, retouching, flash design plus maybe some logotypes and posters design.

The problem here, as indicated in the thread on photo.net, is that the color 0,0,255 in AdobeRGB (or even sRGB) is way out of the screens gamut.

Because of the way the "input" profile is converted too the monitor profile, you get a hue change.

Impossible. I've opened plenty of images embedded with Adobe RGB as the source profile. Blue remains blue coming down to my shorter range monitor profile. The theory sounds correct, but is wrong. If it were true, such a shift would happen with any monitor profile.

On any computer, Mac or Windows, the monitor profile is the last conversion you see regardless of your color choices in Photoshop. You could have a file with Adobe RGB as its color space and Adobe RGB as your working color space in Photoshop. Fine and dandy there, they match. But in order to display the image, ColorSync must convert Adobe RGB to the monitor profile for display. It cannot display Adobe RGB directly to your screen.

Now, you can choose Adobe RGB as you monitor profile and eliminate that conversion, but then of course you have no monitor profile. You're trying to force the monitor to display a color space that it can't possibly succeed at. Colors that are outside the monitor's capability will be clipped. The monitor can't magically display Adobe RGB's entire color range simply because you chose it as the monitor's profile.

As has already been proven, blue remains blue when another monitor profile is chosen to display a file embedded with Adobe RGB. It's the profiles he's creating that aren't working.

I've also had a problem with blues and purples when using third-party monitor calibration, specifically the Spyder 3 Pro. I've posted the problem in more detail here, along with responses from AppleCare and the Spyder 3's technical support guys:

It's still an unresolved issue for me though...
