Yes, a monochrome will only take a black and white image in native format. To produce a colour image, you need to take images through different filters (usually red, green and blue) and then combine them with an image processing program.

Colour chips take colour images out of the box. The chip has pixels with different responses as if they were covered by an R, G or B filter. These are then combined to form a colour image.

The resolution of colour CCDs are lower than monochrome - with mono, all pixels are devoted to each colour in successive images. In a one shot colour camera, one image serves to provide all 3 so the number of pixels to take blue for an image, for example, are about 1/4 the total pixels available.

Hope that helps
