Why is the image from my colour camera monochrome (black & white)?

Colour cameras have individual red, green or blue filters over each pixel in a pattern called a Bayer matrix. This allows software to generate a colour image using a process known as ‘de-Bayering’. This process only works when the image is taken with a cameras native resolution (1×1 binning). Any higher binning will combine pixels of different colours which destroys the colour information and leaves you with a monochrome image.
