How can we define the color black ?

Black Colour can be defined as the visual impression experienced in directions from which no VISIBLE LIGHT reaches the eye

We see things in different colours because light (usually white) reflects off surfaces and reach our eyes with a different frequency, for some is absorbed. When NO light reach our eyes, it simply appears as black. You can see this as some form of 'natural default' (i coined this term myself). \n\nTo help your understanding, think of seeing a piece of paper filled with different patches of colours and holes, placed in front of vaccuum space. The black that you see will be the holes where no light get bounced off. \n\nHope this helps=)

In real life, everything no matter how black reflects either a tiny bit of light or infrared rays.  Even if it's completely black, we could still located with sound or radio waves.  \n\nBy the way, notice that the stealth fighter and bomber are black.\n\nIn scientific terms, something that is completely black can still be found by following light sources behind it because by definition, a black object either blocks or absorbes light.  So it has to disturb light sources coming from "behind" it.  By the way, that's how many plants, moons, and black holes were proven, as I recall.

All things are appear black if they are not lit.  Our eye sees black where there is an absence of light.\n\nRegarding sunlight specifically.  Look at flowers or plants in your home at night.  They don't appear black in artificial light do they?\n\nThe substance that most plants use to absorb light is called chlorophyll.  It happens to be green.  However there are lots of other things in plants that have other colours.  In the leaves they tend to be masked by the predominance of chlorophyll.\n\nAs a plant starts to die,it looses its chlorophyll and the other colours become more visible.  That is why fall leaves have different colours for different plants.\n\nAs a side note, the colour you see on an object is actually the light that is not reflected from a surface.  So something that we see as green has actually absorbed most of the red light reflecting, to your eye, only green.

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

From my own experiences, when we use it it has more of a friendly meaning. When others use it, most of the time it's used in a derogatory way.\n\nIMO I don't think anyone should use it, black or otherwise.

Depends a bit on the colour of your skin too... but traditionally it would be red or black

white all light, colors are the rays absorbed when all othes don't, black is the absence of color, NO THERE IS NO COLOR.\nI took a painting class where the professor took awy the use of black because of that color theory, we had to make dark shades, given that we were painting something someone could see.

I suppose the answer is ultaviolet but as it is outside the visual spectrum of elctromagnetic radiation I can't see how you could define it as a coloUr.

It uses different proportions of the three colours to get black, but true black can only be achieved by a black ink cartridge.\n\nIt may be your printer will take the black cartridge too.
