no, black and white are NOT colours. get it through your thick skull.
btw, that doesn't prove me wrong. it merely says that both achromatic and monochromatic images are nuetral. it does not say that they are the same thing. because they aren't. why would they have different names if they were the same? sorry m8, but you're wrong.
Actually, white is a colour, black is not.
Do you really want me to start talking about colour spectra and photon absorption?
Let's look at in in terms of RGB values on computers.
White is defined as 255,255,255. That is 255 Red, 255 Green and 255 Blue.
Black is 0,0,0.
That means that yes white is a colour, black is not, and grey makes up every neutral value in between.
Sure, achromatic might be a more correct term, but monochromatic is still correct, and still widely in use.
Again though I'll just quote something from Wiki that proves you wrong, again.

For an image, the term monochrome is usually taken to mean the same as black-and-white or, more likely, grayscale, but may also be used to refer to other combinations containing only tones of a single color, such as green-and-white or green-and-black. It may also refer to sepia displaying tones from light tan to dark brown or cyanotype (“blueprint”) images, and early photographic methods such as Ambrotype, Tintype and Daguerreotype, each of which may be used to produce a monochromatic image.
