If dark is the absecence of light as I have heard than black has no color. means black people are colorless?

The color you see is that light that reflects back to your eye.  People with darker skin absorb more of the light that comes their way.

Lets break down the words "white people" and "black people" take out the colour what do u have PEOPLE IT DOESNT MATTER THE COLOUR OF YOUR SKIN IT JUST MATTERS OF WHAT KIND OF PERSON U ARE! WE ARE ALL PEOPLE. In this world we are all brothers and sisters nomatter what the colour

I think that blind people would have their own ideas of what things 'look like' based on the things that are explained to them.  but while you cant explain color necessarily to a blind person, other things you can, and sound helps too. some blind people have very blurred vision and are still able to make shapes out. i believe that based on what they imagine things to be, thats what they dream. maybe just mostly shapes. just as we dont know what (a) god looks like, we all imagine and dream up something we belive him/her/it to look like, even though there is societal influence on the image in question. i think its somewhat ignorant to think that blind people dream in black and sound...

Well, I don't like the term "coloured" for people that have dark skin. It's rude and it's wrong. Then what does that make me, clear? Invsible? Why do we have to pay so much attention to people's skin colour? Why can't we see people as people? We all breath, bleed and breed the same ways. I don't see a difference. I just see people.

Assuming they are completely blind, it's like having no eyes at all, in which case they would "see" nothingness.  Blackness would indicate an ability for your eyes to pick up at least some form of light, and completely blind people can't pick up any forms of light at all.

Dark does not push light away, the light is what is moving. Using your example of "over the horizon", the sun (which produces light) moves to the other side of the earth (where we can't see it) then we see dark. But dark does not move, it is just the term we have come up with for what it looks like when there is no light present.

dark is merely an absence of light.  Dark does not radiate.\n\nYou can biuld a big box and stop light getting in, but the box would be ineffective for anyone outside of it.\n\nYou could always try making a black hole.

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

Because like black, white is not a color either.

Sorry but darkness is not a measurable thing. the absence of light however is! The absolute absence of light leaves the condition referred to as darkness. likewise cold does not exist only the absence of heat. thermal dissipation is the term I believe so I guess we could call darkness, photonic dissipation? wink wink nudge nudge.

black is a colour!\nno colour would be clear, invisible. if that was the case you would then see a bubble of magnified/distorted/warped space stars behind it. but that's not the case.\n\nimagine seeing a black hole with your eyes. you would see stars everywhere except at the hole which would be black...colour.\n\nisn't black not the absence of colour but rather the accumulation of all colours?

Dark is the absence of light.  It has no speed.

Cold is the absence of heat. Hate is the absence of love. Dark is the absence of light. You can quote me on that.

dark is the absence of light. This may sound glib, but on a quantum level, the concepts on light and dark (and most other human experience) are non-sensical - like asking what the colour red ate for breakfast.\n\nCurrently, light is composed of photons to which our eyes have a sensitivity, and we "see". It is thought that photons and all other energy and matter, is composed of different sized strings vibrating at different frequencies and patterns.\n\nWhat is darkness? It is MOST LIKELY, the absence of these photons (and strings) - but then on the other hand, according to quantum theory, it may not - it could be that the darkness in composed of strings too.

Black is void of anything. So traditionally, story tellers and Spiritual leaders choose black. It is sort of scary to see something with no reflective value and devoid of light, don't you think?? I wouldn't be scared of a woman or man in pink, in an alley!  would you?

Technically (and scientifically) black is the absence of all color, whereas white light contains all color within it.  If however, you are blending paints or playdoh, you probably know that "all" the colors put together tend to look brownish-black, and not white.  Therein, I imagine, lies some confusion.\n\nDespite forays into paint and clay blends, the science still holds.

This is partially true, partially false.\n\nWith regards to purple, most people would agree that purple light is always some mixture of reddish and bluish light.   I.e. you can imagine two knobs, one raising and lowering the red and the other raising and lowering the blue, and you can get many shades of purple.  There may be other hues added in as well, but there is *always* red and blue (if not, we rarely call it purple).\n\nIn other words, if we didn't have the word "purple" in our language, we would probably call it something like "reddish blue" or "bluish red".\n\nBut we cannot do the same with red and green.   We have a very hard time imagining, or pointing to, a color that is "reddish green".  If given only a red and a green knob, the result will be make the color more or less neutral (gray or white).\n\nLikewise with blue and yellow.  (Some people will respond that green is bluish yellow, but that's because many people are used to mixing pigments on paper ... we're talking about mixing lights.)\n\nThese two pairs,  red-green and blue-yellow, are *fundamental* pairs.  We call them "oppositional".  (There is also a third opponent pair ... light-dark ... but as we're just talking about color here, we can ignore that one for the moment.)  This is called the "opponent theory" of color vision and is associated with Ewald Hering.\n\nSo in that sense we can call these four colors "fundamental" hues"  because all color we see can be mixed using knobs of these four colors.\n\nPeople will also wonder about the red-green-blue primaries, and the fact that we know we have red, green, blue photoreceptors in our eyes.  These would also seem to be fundamental hues (as evidenced by the computer monitor on which you are reading these words ... that monitor is able to simulate a wide range of colors using just red, green, and blue).\n\nThese two theories ... the "opponent theory" and the "trichromatic theory" competed for a long time until we found a way to reconcile them.  Basically, we have three types of photoreceptors, but they are wired in a way in our retina, that by the time signals are travelling down our optic nerve, the red-green are antagonistic signals as are yellow-blue.
