some measured color data

I agree with you. The problem with this particular thread and the OP attitude is that he seems set to prove the D7k has some basic flaw re skintones rendition, which is ludicrous, and that the D70 is so much better. There are people that still think the D2x produces better skintones than any camera out there, including the incredible D3x.

This is similar to Oly users' claims that only Oly cameras produce good colors.

The internet is full of wishful thinking feeding mythology.

If one checks the color depth indexes for a few Nikons, including the ones mentioned in these posts, at DxO Mark RAW tests, we see that there are 3 groups: the early 6MP CCD sensor cameras at 20bits, the 10MP CCD sensor generation and he first two generations of CMOs APS-C sensors (D200, D2x, D300) at 22 bits, then the D7k sensor and D700, both at same level (23.5 bits), then the amazing D3x's sensor (24.7 bits), see list below.

If one takes into account that the D3x's sensor is 2.25 x larger in area as the D7k's, that is exactly reflected in the 1.2 bit more in color depth, so CFA and algorithms used for D7k are at about the same technological level as those of the D3x's.

D70 - 20.4 bits
D300 - 22.1 bits
D2xs - 22.2 bits
D200 - 22.3 bits
D7k - 23.5 bits
D700 - 23.5 bits
D3x - 24.7 bits

Here is how DxO Mark comment on their score:

"The best image quality metric that correlates with color depth is color sensitivity. Color sensitivity indicates to what degree of subtlety color nuances can be distinguished from one another, often meaning a hit or a miss on a pantone palette. Maximum color sensitivity reports, in bits, the number of colors that the sensor is able to distinguish."

So, all this about D70 or D200 or D2x having better colors than D7k or D700 or D3x are not really justified by the measurements, and all these "samples" used to prove any of these assertions should be seen as the results of poor technique, if they are really poor in color rendition terms. As scientists would put, "anecdotal evidence", usually to the taste of the people that choose which "anecdotes" to show.
