That is absolutely correct, though "true" color I'd debate...three
color/pixel camera yes.

The fact that the Bayer pattern sensors have more positional information is
why they technically have a higher resolution (in the dimensional sense, as
opposed to the color sense).  But I have always not liked them being called
N MegaPIXEL sensors.  The are truly N MegaSENSOR sensor arrays, since one
sensor element does not have sufficient information for a pixel, and pixels
are either monochromatic (grayscale), or contain full color information
(RGB, CMYK etc.).
