How did colours come about?

>>>>> Colors are just light waves that are traveling at various speeds.\n\nUmm, the speed of light in any medium is a CONSTANT. Light waves emitted by objects in air can't travel at various speeds. There is only one lightspeed in air.\n\n\nAnyway, colours 'came about' as an inherentpart of the setup of the universe. There is no other answer. You might just as well ask how height came about. It's an inherent function of our universe. If it were any othr way it seimply wouldn't be our universe and we wouldn't exist to realise it had changed.

Actually, it was the fruit. It originated in China and worked its way around the world until it was introduced in Europe, where its name was derived from the Persian word for the fruit. The town of Orange in France was also named for the fruit and the color was derived from the color of the skin.

To differentiate it from red which is called red.\n(joke couldn't resist)\nI think there is no reason for the word blue except whoever was in charge of naming words named it blue.\nDo you like it?\nThere was a game book where they made up a condition of life and then named it.Very funny and we who read  it could relate.  For instance a person who likes to practice outer body experience just before he has sex might be called........voyeur. or  retroactive.\nSo you might try this yourself. when intrigued by a certain condition of life.

There is 2 ways to spell it. In the US, we spell it color. In England, they spell it colour. It is the description you give to an object in terms of how it looks. Color or colour (see spelling differences) is the perception of the frequency (or wavelength) of light, and can be compared to how pitch (or a musical note) is the perception of the frequency or wavelength of sound.

Colour is all about light.  The amount, quality, and colour of light can make a difference.\n\nYour clothing is reflecting light, thats how we see what colour it is, it can easily reflect to your eyes.

well to start rods have nothing to do with seeing colour and cones come in three types... the majority of them green and red and the minority blue...\nanyone that has done primary school art knows that any colour can be made from the primary colours of yellow, blue and red plus white (the spectrum) and black (the absence of colour)... green is yellow and blue mixed together and added with the red there are our three primary colours... then we have light (which is white) and the absence of light or colour black... somewhere in this combination you have all the factors required to "mix" any colour and therefore the ability to "see" any colour... this is further evidenced by the colour blindness where a defect in the cones results in an inability to see certain colours (and presumably one could pinpoint the particulary green or red cones affected by the colours which a person can or can't see... many friends of mine who are colour blind say that blue is their favourite colour... the blue cones act as a blue amplifier.. perhaps this explains the human fascination with the beauty of the sky and the ocean.. therefore even if the yellow aspect of the green cones is defective causing difficulty with oranges and browns etc the blue perception remains intact...

Colors is everything! They make the world more exciting! How could you live with a world that was just black and white??? THAT'S JUST CRAZY!!!

If there are Colours Join the Colors same to the same... Like I mean join the same colors... together...\n\nok.. i actually have no idea..\n\nMaybe it would help..

Red because it can represent so many things. Love, passion, anger, chaos etc.

If your talk about the pigment, three are  three primary colors (red, blue, yellow)\norange is mixture of (red and yellow) and blue is opposite\n\nAdd them together you get black\n\nIf your talking about the light color wheel (the primary colors are red green blue (you mix red and green to get orange, the opposite is blue.

Each pixel on the screen is composed of three colours (red, green, blue) that each vary in intensity and blend together to give the illusion of one pixel colour due to their small size.\nWhen a drop of water lands on the screen, it magnifies the individual pixel colours such that they appear to be distinct.

From a physics/physiology standpoint, we have color because light waves come in different lengths and our eyes perceive a limited band of thoses lengths with differing responses by light sensors in the eyes.\n\nFrom an evolutionary standpoint, color vision (as opposed to black and white), gives us a great deal more information to process our environment.  For instance, a brightly colored bird might hardly be visible to an animal with only black and white vision, but we see it easily, even against a confusing background.  Color can help us see the difference between animal (browns) and plants (greens), healthy(a child covered in mud) and unhealthy (a child covered in blood), and other differences that are more easily recognized due to the greater information richness available.

You may not realize it but in one qhestion you have asked for knowledge that is gained taking a university level physics course.\n\nSince I am a lousy typist, I will give you some clues that should allow you to visit Google and gather the answers you are looking for.\n\nThere are twi type if color mixing.  The additive method, used by painters, where you mix yellow and blue to get green.  \n\nThe subtractive method, used in optivs and video technology, where colors are filtered out as opposed to added in.  In this method the primary color are differet.\n\nIf you want a much more thorough explanation, you may want to examine the study of "Chromatics".  At look at how rainbows are created might help as well.\n\n\nBest of luck,\nJeffrey

I grew up in NZ, (very beautiful place). The first thing everyone marvels at if they land there in daylight, is the exquisite contrast of the incredibly deep blue sea and the deep green landscape.\nThe typically followed NZ colours, though, are black and white ( just look at the world famous rugby team the 'All Blacks') also black, white and red, and (less so) blue and the green of 'greenstone' which are the traditional colours of heirachy, adornment and decoration of the native Maori people.

Ordinary white light, like that from the sun, is made up of many different colors all of which have a different wavelength.  Normally, when we see light from the sun, it appears colorless.  However, Isaac Newton discovered in 1666 that when he passed regular sunlight through a prism (basically, a triangular piece of glass), the prism would split the light up into a band of colors. \n\nThe band of colors is called the spectrum which appears in the order of red, orange, yellow, green, blue, indigo, and violet. \n\nWhen it rains, the air is filled with raindrops.  These raindrops act like a prism.  If sunlight passes through the raindrops at the proper angle it is split into its spectrum, which is made up of the colors of the rainbow. \n\nYou can make your own rainbow at home by filling a plastic box with water and placing it near a sunny window.  If the wall next to the window isn’t white, place a piece of white paper next to the window.  Next, place a mirror inside the box of water facing the window.  The mirror needs to be tilted towards the sunlight.  The wedge of water in the front of the mirror acts as the prism and the mirror reflects and image of a rainbow on your wall

with travelling electrons.depending on their wavelength,colours are formed
