If we're being pedantic, black and white aren't colours. They're the absense of colour, and the mixture of all colours (going by light rather than dye style mixture), black on the rgb scale being and white being
You see, the problem there, is that both the terms zero saturation and no hue mean... no actual colour. It's only defining black and white as a colour for laymans terms
You see, if you have zero saturation, that means that the colour value can be whatever, but the amount of that colour in the specified area is 0, so absense of colour.
You'll also find Hue means shade or tint or in fact just plain colour. If it has no hue, it has no shade, therefore... no colour.
Plus Achromatic, literal meaning, is something like without colouring
I've been doing colour based digital image processing all year, I had to teach myself a lot of it, so I picked up a few things about colour on the way

note again, the whole saturation thing.
The "a" prefix means without, so without colour percieved to have a saturation greater than 0 means without a real colour. A saturation of 0 means it is colourless.

Note, dictionary.com doesn't use scientific terms, but rather laymans terms.
In scientific terms, especially those referring to vision, black and white are not colours
Now, I'mma shut up and let people get back on topic.

Achromatic Colors
The "hueless" colors black, gray, and white, that is, the whole range of gray levels between black and white.
ISO Definition: Perceived colors devoid of hue. The color names white, gray and black are commonly used or, for transmitting objects, colorless and neutral. (Source: ISO 9241-8 (1997-10-00) ISO/TC 159)
Funny stuff.
