Getting the green out of the MBP SM LED screens

The default profile with the new LED screens was looking extremely green. I've seen a few people comment about this, but nobody was sure whether or not it had to do with the LEDs or the profile. For the record, it's the profile.

I just calibrated my screen using the Eye One system from GretagMacbeth and the before and after results were dramatically different. I don't have a photo of the difference, but the major green push is completely gone now.

SM in thread title?
 
What kind of results do you get using the color calibrator in System Preferences?
 
The color calibration in the system preferences is still way off. As far as I can tell, it doesn't really give you independent rgb controls, it just lets you choose a white point. But it looks like whatever it thinks is the standard white point is just way too green.

I've attached the icc profile that I've generated. Give it a shot and see how it works for you. Every monitor is different, but this should get you a lot closer to an industry standard calibration than the built-in profiles do.

how do i put this in the list of display profiles?

I'm not sure of the exact location, but you can easily find it with Spotlight. Just search for one of the existing profiles and you can track down the path that way.
 
I really don't understand this. Apple sells computers meant for the "pro" users and installs a color profile for the new monitors. True, the monitor's aren't designed to do heavy color-proofing work on them, but a bit of accurancy wouldn't be wrong. Why the hell would they supply a color profile that makes no sense? Perhaps they forgot to update the profile to match the new LED-backlights or something like that?

Oh and vforvegan, thanks alot for your color profile, I'll give it a shot in a couple of days when my MBP comes in :)

That would be my bet as well, not remembering or thinking to update the legacy profile. All in all it sounds like a harmless mistake that causes no real issues other than re-calibarting it.

Thanks for the profile! At first I thought "wow, this looks a lot more blue", but the colors are much richer now.

I know, it feels really blue at first, but then you realize that you've just become used to seeing everything with a green tint. I've got about 4 monitors that I've calibrated using the same device, in both Windows and OS X, and this profile definitely brought my MBP inline with the rest of the screens.

I did the color for a short film and saw the results on a $30,000 Sony HD reference monitor and it's amazing how far off the default Mac color profiles are.

Just to note, when I calibrated the MBP LED screen in Vista, the change wasn't nearly as dramatic as in OS X. For whatever reason, the default profile in Vista isn't nearly as far off as the one in OS X.

Also, for anyone that is doing color accurate work, this profile has a temperature target of 6500k and a gamma of 2.2.

Most real pro-users have their own calibration equipment and calibrate all their displays the second they open them up.
 
yeah thanks a lot this looks much better i agree that it looked blue at first but this looks really good now.

Well ofcourse, I never claimed they don't :) I was actually more referring to the 6-bit panels, and now the added wrong color profiles, a "pro" user would expect better. I know, I'm a nag but 8-bit panels would be nice (I know this is not realistic at the moment, but that's not Apple's fault)...

But they could've at least provided a matching color profile and I'm sure they'll address this (minor, but easy to fix) issue in an update.
 
Is this an internal profile only? It would be a bit silly to distribute a profile that accounted for ambient lighting. To be honest, I think it's a bit of a crapshoot to assume this profile would be accurate across different peoples' screens.

I skipped the ambient light measurement step when I created this profile. I'm not assuming that this would give accurate color for any screen other than mine. I don't think anyone is assuming that this is the case. Obviously anyone that is serious about color is going to do their own calibration.

But at the very least, it will help people that aren't doing their own calibration neutralize that god-awful green push that Apple's profile seems to have.
 
now i am brand new to mac, and will hopefully be getting a MBP within a month but all these reports on the LED screens are making me a bit anxious about my purchase. Now since i really dont know my way around mac, could anyone tell me how to access the display profile to set the above attached file to my computer after I download the file into the directory given above. All i need to know is how to access the display profile to apply the downloaded profile.

Whoa! I didn't think I had a yellow/green tint problem until I tried your profile. Now when I toggle between this and "Color LCD" the difference is painfully obvious. I'd say we now have clear evidence that the Apple-supplied profile is indeed flawed.

NOTE: Everyone with an LED-backlit MBP should give this a try!

that's the problem! Unless you've calibrated to get true whites, you won't notice the yellow cast....

To be fair to Apple, do try to name one other laptop that uses a > 6 bit LCD display that is as sleek as the MacBook Pro.
 
Thanks!

Wanted to say thanks so much for the profile! I am using it & love the difference it made.
