The question:
Are black and white colors?

The answer:
1. Black is not a color; a black object absorbs all the colors of the visible spectrum and reflects none of them to the eyes.

The grey area about black:

A black object may look black, but, technically, it may still be reflecting some light. For example, a black pigment results from a combination of several pigments that collectively absorb most colors. If appropriate proportions of three primary pigments are mixed, the result reflects so little light as to be called "black." In reality, what appears to be black may be reflecting some light.
In physics, a black body is a perfect absorber of light.

2. White is a color. White reflects all the colors of the visible light spectrum to the eyes.


2. White is not a color.
... but .... in some cases you could say that white is a color.

The grey area:
Technically, pure white is the absence of color. In other words, you can't mix colors to create white. Therefore, white is the absence of color in the strictest sense of the definition.

However, when you examine the pigment chemistry of white, ground-up substances (such as chalk and bone) or chemicals (such as titanium and zinc) are used to create the many nuances of white in paint, chalk, crayons - and even products such as Noxema. It's worth noting that white paper is made by bleaching tree bark (paper pulp). Therefore, you could say that white is a color in the context of pigment chemistry.
The answers:
1. Black is the absence of color (and is therefore not a color)

Explanation:
When there is no light, everything is black. Test this out by going into a photographic dark room. There are no photons of light. In other words, there are no photons of colors.

2. White is the blending of all colors and is a color.

Explanation:
Light appears colorless or white. Sunlight is white light that is composed of all the colors of the spectrum. A rainbow is proof. You can't see the colors of sunlight except when atmospheric conditions bend the light rays and create a rainbow. You can also use a prism to demonstrate this.

Fact: The sum of all the colors of light add up to white. This is additive color theory.
