bloodhound Posted April 16, 2004 Share Posted April 16, 2004 I am sure its not a colour. I am sure white isnt a colour either. and is there such thing as particles of darkness? and do they travel and the speed of light? Link to comment Share on other sites More sharing options...
YT2095 Posted April 16, 2004 Share Posted April 16, 2004 black is not a color, it`s the default state. White is an equal mix of all colors in addative synthesis (using colored light to generate as opposed to subtractive where filters are used to block all but the specified color). the speed of darkness would therefore be the rate that light leaves the area Link to comment Share on other sites More sharing options...
Sayonara Posted April 16, 2004 Share Posted April 16, 2004 A colour is only a label we assign to a mix of light. #000 is just as valid as #FFF. Link to comment Share on other sites More sharing options...

iglak Posted April 17, 2004 Share Posted April 17, 2004 black is the absence of color dark is the absence of light color cannot be detected without light the absence of light would appear as the absence of color Link to comment Share on other sites More sharing options...

Misodoctakleidi Posted April 17, 2004 Share Posted April 17, 2004 Black absorbes all light, white reflects all light. Most of the universe is made of darkmatter but no one really knows what it is. Link to comment Share on other sites More sharing options...

swansont Posted April 17, 2004 Share Posted April 17, 2004 No' date=' black [i']is[/i] a colour. Colours are just labels. What it isn't is a colour of light. There are two distinctions to be made. Color as a frequency of light, or color as perceived by our eyes. Neither white nor black is a frequency to be found in the spectrum. But neither is brown, or a number of other colors found in a crayon box or at the local home improvement/paint store. Those colors are how combinations of frequencies are perceived by our eyes.

iglak Posted April 17, 2004 Share Posted April 17, 2004 We have defined color as a a specific wavelength of light, or a combination of specific wavelengths. Color is also defined as what color of light an object would reflect if it were in white light. in red light, a box of crayons would still be whatever color they are, they would just appear as a different color, more red, thus function incorrectly (as YT said). we all sorta know this, but i felt it needed to be directly mentioned Link to comment Share on other sites More sharing options...

Glider Posted April 18, 2004 Share Posted April 18, 2004 I think it shows deep insight and self awareness on the part of our US cousins. Either try to teach American schoolkids to spell properly (e.g. colour, behaviour, haemglobin, foetus), or make the words easier to spell (color, behavior, hemaglobin, fetus). Which way would you go?

It has started appearing in essays and research reports submitted by students (can you believe that?). It's insidious, you begin to see thing like "4 example, previous research suggests...". I hate it and I've warned them that if I see it, I'll stop reading the report at that point and fail them. No, it was the "extra vowel" tax, without representation, that we were rebelling against.

Glider Posted April 19, 2004 Share Posted April 19, 2004 True, but it makes it no more acceptable. I know language must evolve, but 4 is a number, 'u' is not a word and sentences containing such appreviations are not acceptable in formal documents. Even accepted abbreviations such as can't, won't and don't are not acceptable in formal academic writing. Students are taught this, and yet they persist...little weasels!
