What makes up the colour black ?

Answer 1

all the primary colours mixed together

Answer 2

with paint, since there are three (not 4) primary colours which combine top create all other colours, then it is
red
yellow
blue

Reasonably dark black mixtures are possible with the if you use a very dark blue or cyan paint but they are a pain to mix and they do not produce the maximum depth of dark

So other 'pigments' are added because primary colours cant achieve a true black. Carbon is the best known black in nature - Carbon Black, Ivory Black, Vine Black, Lamp Black are all carbon based.

Incidentally a true black i.e. one which absorbs equally all colours of the visible spectrum is very difficult to produce. All blacks tend to have a red, blue or green undertone where that s-wavelength is not 100% absorbed

however, this colour theory is not true for lighting effects, TVs and computers. - that's a whole other theory

Answer 3

Black

Answer 4

dear friend

Black is not a colour. it shows the absence of any other colour.
White is the combination of 7 colours (rainbow).

Answer 5

Something that’s black absorbs all the light of any color that hits it. Regular pigments absorp some colors well but not others- the color you see comes from the light they don’t absorb.So you want to mix some different color pigments- say red and blue- to try to absorb as big a range of colors as possible. You may also want to use some dark green or yellow other different pigment to adjust the color if you get something brownish or purplish. You want to use the darkest starting pigments possible, because you need to get all the light absorbed before it has a chance to bounce back out of the surface.
It’s pretty hard to get a good black by mixing regular colored pigments, because these are chosen to absorb very little of some colors of light. That’s why ink-jet printers usually use separate black ink, with pigments that absorb a broad spectrum of colors, rather than a mixture of the colored inks.

Answer 6

All four primary colours mixed together in equal quantities. Red, Blue, Yellow, Green = Black.

Answer 7

Apparently, Black and White are not colours.

Answer 8

What makes up the colour black in WHAT. In Skin? due to the tremendous amount of melenins, exposure to sunlight, enviromental factors. Black is lack of light, that's the best definition.

Answer 9

White reflects all colours and black absorbs all colours

Answer 10

It depends on if you're using additive or subtractive color. Additive color is used in print and is the combination of Cyan 75%, Magenta 68%, Yellow 67% and black 90%. With subtractive color, it's the absence of Red Green and Blue light (as in a projector or TV).

Answer 11

it depends on whether you are talking about pigment or light. if you are mixing together light to make colors, you must use no (visible) light to make black. if you are mixing pigments together to make colors, then you must mix together pigments capable of absorbing the entire visible spectrum. your best bet there is just to use carbon, which does the trick on its own. But we see black when less than a some threshold of visible light is reaching our eyes, and light is either generated by a light source or it is reflected/refracted to our eyes.

to say that black is not a color, while I assume is technically correct, is limiting to our usage of language. for example, many of us would agree, at least ostensibly, to the statement "There are 64 colors in this box of brand X crayons." when in fact, one of the crayons is black. We don't say, "I have 59 colors, plus white, light gray, gray, dark gray, and black." It is just awkward to have to answer that some thing is "no color"... I think we may as well accept black as a color. Certainly in physics or optics black will retain its more technical meaning.
