Can you post a screen shot and a sample NEF to DL and try?

What is your Aperture version?
Are you having the problem with a wrong tint with artificial light or low light, or also in bright sunlight?
You may want to have a look at the threads with similar problems to compare symptoms:

Here is a screen shot from Aperture. Images on the right are after I double click on them to have Aperture render the raw file. Image on left is the camera generated jpeg that is embeded in the raw file prior to being overwritten by Aperture engine. No corrections applied.
Here is a link to a sample Raw file that I shot this morning the blue green look seems most apparent where bright sunlight is hitting the image

Bright sunlight seems worst see my reply to Clem.

Yes I see the shift you refer to. Seems less saturated to me, not more, but I do see the slight blueish-ness. Might try a custom camera preset for that model as a default, if you can find a raw fine tuning adjustment that moves the picture more in a direction to your liking.

Oh and Aperture Version is 3.4.4

I have been working on a preset off and on today. Seems like the Aperture Raw Decode should be a little closer to reality than it is. It seems that a manual 5600K 11 Tint is a little closer to reality.
Thanks again for your input

I have been shooting my D800 for over a year now, and I have not observed what you are discussing, particularly in outdoor, natural light situations.
I have downloaded your NEF, and imported it into Aperture (3.4.5). I notice two things right away: 1) you are using Uncompressed NEF, 14 bit recording; and 2) you seem to have a custom White Balance. The former should be of no matter, but would be interested if you have been able to discern any advantage over Lossless Compression, 14 bit?
However, the important concern is with the Custom White Balance impact on the rendering of NEFs in RAW in Aperture. I am planning to do a study of this, and am wondering if you could test your resutls in similar shots with Auto White Balance rather than any preset (yours or the camera standard presets)?
I by practice only shoot Auto White Balance (and RAW), but recently I have found benefit to using a preset WB when shooting video since that result will not be modifiable later on the computer. After doing this, I have sometimes forgotten to reset the WB to Auto before again shooting stills in RAW, and the resulting difference vs once reset has been curious.
While it is well known that Picture Controls when used and shooting RAW will likely result in wide differences between the Camera Preview and Aperture's first rendering, I am less certain what the dynamics of White Balance settings and first rendering in Aperture.
Thanks for the test image and chance to discuss this.

Btw, with you image in Aperture, I chose Natural Gray for the WB test, used the tree trunk as proxy for Natural Gray, and achieved what to me is a much more realistic rendering. I think this points to your Custom WB as an issue in the saturation/tint observation.

I have done the same thing, and I agree. It does help, but the oversaturation and bluish green cast perisists even though it can be toned down as you mentioned. I have noticed that there is much discussion of this problem with the d800 in photography forums around the net. I am in the process of testing using the tint controls in the d800 to add a litlle magenta/yellow to see if I can neutralize the cast. I shoot everything in raw and can make adjustments after the fact. However I have found that the closer the raw file capture is to reality, the better. Auto white balance, since it tends to neutralize colors in nature is not how I shoot. For example a brilliantly colored sunset will be "balanced" to the point of losing the oranges and pinks that existed. I usually shoot in daylight white balance as a throwback to the film days and if I need to tweak for shade etc I do so in post. I am a nature photographer and so starting out with something at least close is important.
I am still experimenting with the difference between the lossless compressed and uncompressed 14 bit NEF files. So far I can not tell the difference. I have been a professional nature photographer for more than 30 years and haven't experienced anything as pronounced as this before.

Thanks for all of your assistance on this.

Whether there is something unique to the D800 in this discussion, I do not know. But limited Google searches indicates that similar issues have been discussed in this tint regard and custom white balancing for both Aperture and Lightroom.
Most of my shooting is inside, and in venues where I would not have the chance to develop much thought about manual WB. So, I have become accustomed to needing to adjust WB in Aperture, post production. As I said earlier, I only had to confront setting a certain WB due to needs when shooting video where privileges of RAW are not available.
Thinking about nature shots, and good outdoor light may be something I need to consider. But I am not convinced that customizing the WB is going to be rewarded in initial renderings in Aperture. Whether this is related to the implimentation of the Digital RAW coding by someone other than the camera manufacturer, I do not know.
