Quoting "M. Adam Davis" <spam_OUTstienmanspam@spam@gmail.com>:

Human vision is significantly less sensitive to chroma (color) detail than
to luminance (brightness) detail. This is taken advantage of in analog  
television signals,first developed in the 1950s, where the chroma  
bandwidth is but a fraction of the luminance bandwidth, and in digital  
video where the chroma signal is sampled at something like 1/4 of the  
resolution of the luminance information. But that's a form of (lossy)  
compression.

What actually happens at the sensor is another kettle of fish again:
