Well how u exactly define a black colour? 1>summation of all colours, 2> presence of no colours, then?

Question

summation of all colours is zero!!! then i suppose there must be some thing like colours and anti-colours? what's must be there basis? and what would u get if usubtract white from black???????
Please its driving me crazy everytime i think of it, but still i starve for the answer . plzzz even suggest i site where can i put my such unussual viewpoints?

Answer 1

There are two ways to make colors, mixing light and mixing paint.

If you are doing light, the absence of all colors makes black. If you sneak in a speck of one color it will be the only one you see because all the others are missing. You can not subtract the white because it isn't there. Whatever colors were there have already been subtracted and that is why you had black. Try this with a coloring program on your PC monitor because it uses light to make the colors you see there.

If you are doing paints, presence of pigment makes black when you have them all there. If you have black pigment and add white pigment you end up with lighter and lighter gray as you add more and more white. If you don't mix all the basic colors you will end up with just the result of the partial mix. For example if you mix yelow and blue you will get green. Adding red to that will darken it until finally it is so dark it looks black. Try that with oil colors to prove it to yourself..

Answer 2

To understand this you must understand how we see the colour.

Light has many wave Lengths and they represent the colours.

When you see an object as red, it means that, that objects reflects only red band of light and absorbs all other bands.

Black absorbers all bends, so you do not see any colour.

Experiment:

We know that there are three primary colour, Red, Yellow and Blue by mixing this you can achieve various other colours.

So get these colour paint, say one drop each, oil paint or water colour or any other kind(powder). Mix these three good the resulting colour will be black.

So black is summation of all colour.

White is no colour, you are able to see all lights, all wave lengths.

Answer 3

There are two types of colour - pigment colour and light colour.

With light colour (which is the colour of actual light), black is the absence of any light.

With pigment colour (this is the actual colour of physical object like walls or paint) Then black can be made not necessarily by mixing colours but by using very dark dyes.

Pigment colours are different from light colours. Light colours are changed when they meet pigments. Pigments absorb all the colours of light except the colour that they are - for example a blue wall will obly reflect blue light.

Also the primary colours of pigments are Red Blue Yellow and the primary colours of light are Red Green Blue.

You cannot make black from light, but you can make black in pigment - a black pigment will absorb all light.

Normally, I would say 'grey', but black isn't always black. In our colour world, it's usually dark, Dark, DARK blue ... or green ... or purple -- to the point where our eyes perceive it as black, but it isn't. If this is the case, I would say the answer can be found by putting two more of those colours into a box in the sun. Stir them up with a stick and see what you get. Sounds like fun, though, putting them in a blender. Hmm ...

Answer 5

In terms of Perception, Black like Greys and White, is an achromatic colour: a colour without hue and saturation (or "strength").

If the term is intended to be Physical (physical and psychophysical concepts are often confused) and Black refers to a total absence of visible radiation (light) then, if there is no physical stimulus, there can be no physiological response: no response-> no perception-> no colour.

Answer 6

This is an area which has a lot of misconceptions, and I see kid's television shows talking absolute BS about colour all the time.

I know colour theory very well; I am a journeyman in pre-press (technical work to create printable and technically correct computer files) and I have over 20 years in professional colour work.

There are two ways to make colour. Broadly, they can be described as mixing together separate light colours, or as subtracting colours from reflected white light. Technically these are known as additive colour (lights, TVs, computer monitors), or subtractive colour (filters, paints or pigments).

The primary colours for additive colour are red, green and blue. They correspond to the colours that the cones in our retinas respond to, which is the basis for our colour sense. If red and green turn on together, the light appears yellow; if red and blue turn on together, the light looks magenta; if green and blue turn on together it looks cyan; if all three turn on the light looks white. No lights, of course, means it looks black.

The subtractive primary colours are cyan, magenta and yellow -- NOT red, blue and yellow. These colours are capable of filtering out (that is, subtracting) one of the additive primary colours (red, green or blue) from white light that shines through it or bounces off it. Cyan ink removes red; magenta ink removes green; and yellow ink removes blue. Mixing them removes two primaries; if you overprint magenta ink and cyan ink you remove both green and red; the remaining light is blue because blue was NOT subtracted.

In principle, printing cyan, magenta and yellow (CMY) together should make a nice rich black. However, it's not possible to make inks the right colour for magenta and especially cyan. So printing CMY makes an icky muddy brown colour. To fix this problem, colour printing adds a fourth ink, black; that allows accurate colour reproduction in shadow areas. Four-colour process printing is also known as CMYK printing -- they abbreviate black with K because B is already taken, for 'blue'.

Answer 7

it is summation of all colours.we see the colour from the reflection of light that surface reflects.in case of black there is no reflection,it means summation happens.

Answer 8

Black is the absolute absence of light.

Answer 9

black = no color
this screen seems white bcause it reflects all colors and gives u a combination of all colors: white!
leaves r green bcause they reflect green
ur lava lamp is red bcause it reflects red and absorbs the other colors
