why is black not a colour?

Answer 1

Scientifically, black is not a hue (color); a black object absorbs all the colors of the visible spectrum and reflects none of them. This is sometimes confused with black being called 'a mixture of all colors', but that is not the case. In fact, an object emitting or reflecting all colors is perceived as white. Sometimes black is described as an "achromatic color"; in every day life and practice, black can be considered a color, e.g., the black cat or black paint. But not scientifically a colour

Answer 2

Black is what is left when all light is absent. Colours reflect light of a certain frequency dependent on the frequencies it holds. So blue is reflected from a blue object because the the object is reflecting frequencies of light it already holds. So a colour we see is actually rejected light from an object. So if that principal is right then black must be a colour because it is rejecting light that it does not hold

Answer 3

well, it's to do with the cones etc on your eye. they detects colour, but the absence of any ligth reflecting on them to show colour, shows black. Therefore the total absence of colour is black, therefore black can't be a colour, apparently.

Answer 4

black is a colour

Answer 5

black is a colour

Answer 6

To be a colour there must be some light reflected and pure black will not reflect any light.

Answer 7

Black color is an absorption of light and white the reflection.

The absorption of light makes an object dark or opaque to the wavelengths or colors of the incoming wave. Wood is opaque to visible light. Some materials are opaque to some wavelengths of light, but transparent to others. Glass and water are opaque to ultraviolet light, but transparent to visible light. By which wavelengths of light are absorbed by a material the material composition and properties can be understood.

Another manner that the absorption of light is apparent is by their color. If a material or matter absorbs light of certain wavelengths or colors of the spectrum, an observer will not see these colors in the reflected light. On the other hand if certain wavelengths of colors are reflected from the material, an observer will see them and see the material in those colors. For example, the leaves of green plants contain a pigment called chlorophyll, which absorbs the blue and red colors of the spectrum and reflects the green. Leaves therefore appear green.

Answer 8

Black is not a colour because it is devoid of any colour, as is white.

Answer 9

there is no such thing as a color called black. Black is the absence of light. White is the combination of all wavelenths of light. ppl say they have black hair, but really it is very dark brown. you can die your hair "black" but really its a blue tone that they use.

when you mix all color pigments (like of paint) together you get a very dark brown color, but its stil not black...oh even a black crayon is truly not black...its very very dark brown. notice how dark brown and black look the same in a crayola box of crayons?

edit for joe public, black is not a primary. primarys are red blue and yellow. these three colors are said to be pure and make up other colors like green purple and orange. White cant be a primary b/c its encompasses all colors. black cant be a primary b/c it is the absesnce of light.........

Answer 10

physically it is because white has all frequencies of all colours and black isn't one of them. when you see a colour like green on a plant, it is because all the other wavelenghts have been absorbed except for green which is reflected off
