There's an excellent discussion on this topic here:

Colour and tone rendering - CCD Samsung GX-10 (Pentax K10D) vs CMOS Pentax K-3 -

Ultimately it's mostly a question of how the camera processes the raw data, and also an artifact of cmos sensors' increased sensitivity.

What surprised me is the concession that newer isn't necessarily better. Just cheaper.

Selective quote from the link in officiousbystander's post:

During readout CCDs move the electrons from pixel to pixel, like a bucket brigade. They shuffle one-by-one out through a readout amplifier in the corner of the sensor. The big advantage of doing this is that every pixel is measured in the identical same way. The use of a single readout amplifier makes the readout process extremely consistent. Each pixel in a CMOS sensor has its own readout amplifier, and often sensors have A/D converters for each column; this makes it possible to read out the array extremely quickly.
The consistent way that a single amplifier works with the way translates to richer colors. I like to think that a single amplifier can be made a lot more sophisticated and have lower distortion as a result - hence nicer colors. This is only a hunch and I will have to do some research on the topic.

CCD cameras tend to have nicer color but IQ falls apart in bad light. Also, they can't process data fast enough for live view or video.
