The R means RED, the G means Green, and the B means BLUE. This is the arrangement of R (red) G (green), and B (blue) pixels. Did you read something else??? This "Beyer" pattern is how most sensors are made. There are a few odd sensors (eg; interleaved, parallel quadrants, etc.) Beyer Pattern: R G R G R G R G R G R G... (pixel row 0) G B G B G B G B G B G B... (row 1) R G R G R G R G R G R G... (row 2) G B G B G B G B G B G B... (row 3) ...(etc) . .
