Originally posted by Pioneer I much prefer the the CCD sensor color output.
I hear this often enough to reply. First, let me cite this post:
Quote: There's no such thing as "CMOS color" or "CCD color". CMOS and CCD both use silicon photodiodes, and they have identical monochrome responses. The "color" comes from the organic filters that are screened onto the naturally monochrome chip, and those are the same regardless of whether the chip is CCD or CMOS.
There are differences in the organic filters used by different manufacturers, but those different filters could be applied just as easily to either a CCD or CMOS sensor.
A sensor whose red, green, and blue sensitivity curves have about the same amount of overlap as those of a human eye will produce "natural" colors, in other words, ones that can be processed (by the camera's computer, or by an external raw processing program) into something that looks a lot like what the eye sees.
A sensor whose red, green, and blue curves don't overlap as much as the eye's curves produces unnaturally exaggerated colors, but that effect can be substantially reduced in post processing. There's no real reason today to make such a sensor, but some older cameras, whether CMOS or CCD, had that kind of curve. It's probably what you like.
A sensor with curves that have more overlap than the eye reduces color separation, and gains increased sensitivity (high ISO and shadow detail). That's a modern trend, because so many photographers (and reviewers) talk up the high ISO.

Second, let me refer to DxO's color analysis based on the raw output of K-5 and 645D (relaesed about the same moment in time):
K-5
Quote: Sensitivity metamerism index ISO 17321: 78
White balance scales:
R 2.24
G 1
B 1.64
Color matrix as defined in ISO standard 17321:
R 1.82 -0.73 -0.09
G -0.15 1.54 -0.39
B 0.06 -0.46 1.4
645D
Quote: Sensitivity metamerism index ISO 17321: 75
White balance scales:
R 2.18
G 1
B 1.2
Color matrix as defined in ISO standard 17321:
R 1.99 -0.88 -0.11
G -0.19 1.57 -0.38
B 0.11 -0.75 1.64
Both color responses are extremely similiar, with similiar metamerism index just close of 80 (anything above 80 is said to be indistinguishable from natural true colors). If anything, the 645D has a tad stronger red and blue diagonal color matrix elements (less overlap) which may lead to a bit more brilliat than natural colors if not corrected for by the raw converter profile.
Professionals (esp. studio product and fashion shooters) use inexpensive tools like
X-Rite's ColorChecker Passport to calibrate their camera. After doing so, the DxO analysis tells us that no visible differences in color rendition should remain (maybe with one exception, red channel clipping for overexposed images which is 3% stronger with the K-5).
IMHO, there is no such thing as "CCD colors".
