A raw image file includes single luminance values measured at each photosite (a/k/a "sensel" or "pixel well"). Each single value tells how much light energy was absorbed by each photosite. These values are listed in a specific sequence. At this point there is no "color" information in the way you seem to expect. There is only a single luminance value for ...

A RAW file does not consist of pixels with multiple color coordinates. It consists of a single value from each sensor well on the sensor. Those values must be demosaiced by an algorithm that has some knowledge of the Bayer or other filter that sits in front of the sensor wells. These algorithms take the value of each well and those from some small ...
