what or  who named the colors of the visible spectrum?

This isn’t a science question, it’s a question of etymology, the study of words. And every colour name has its own unique history. \n\nSome colour names like ‘red’ and ‘blue’ are ancient, going back 20, 000 years or more. Nobody is quite sure who invented these words or where, but they are ancient in origin. \n\nOther colour names like ‘orange’ are only a few hundred years old and their history is well documented. In the case of orange the word only came into use after the fruit orange was imported into Europe from China about 500 years ago. Until then the objects we say are orange today were simply described as red or reddish yellow. There is a common English flower which is clearly a bright orange colour that is still called the scarlet pimpernel because it was named in the days before orange entered into the English language\n\nEvery colour  name has a history all of its own. Some are not well known and date back to the dawn of the various language groups. Other like pink or orange are reasonably well documented and only came into existence within the last few hundred years.

According to Astronomers Karl Glazebrook and Ivan Baldry at Johns Hopkins University :\n>>All the light in the universe from as far back as several billion years ago averaged out to a shade of turquoise, somewhere between pale turquoise and medium aquamarine. Such color however was revised shortly due to their claim that the software program  used was calibrated incorrectly. They said that the average colour of the universe is actually "cosmic latte" (beige colour).♥

no i don't have any info. but i think we're able to detect all of the colors of the spectrum.

Wow, what a prick...he probably knows less science than you do. He's definitely further off from the truth!\n\nColors as we see them are nothing more than photons. Which is electromagnetic radiation. We perceive different wavelengths (or frequencies) as different colors. So in a way colors do have a frequency associated with them. Blind people cannot recognize these though. The only way humans can recognize electromagnetic radiation (in the visible zone) is by seeing. By definition a blind person can't do that.\n\n(Well, technically we can also feel photons if lots of them hit us...as heat. But we cannot differentiate different frequencies, and the intensity of the light has to very extreme, like sunlight).

using simple physics\n\nThe blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through. Little of the red, orange and yellow light is affected by the air.\n\nthe grass is green because the other colors are absorbed and only green is reflected. Grass and most other plants are green because they contain a pigment known as chlorophyll.\n\nSun isn't really yellow. The color yellow is a purely human interpretation of a collection of radiation that hits the retinae of our eyes and gets processed by our visual cortex.

The CD acts in a similar manner as a prism and splits the light into it's component parts.  Visible light is actually made up of several colors (The colors of the rainbow: Red, Orange, Yellow, Green, Blue, Indigo, Violet) and if the light is refracted it can split and you can see all the colors of the light spectrum.

It is correct that the visible wavelengths of electromagnetic radiation  are from 400nm (violet) to 700nm (red); but that is because of the way the eye perceives light, and has nothing to do with the way waves interact with each other.  Also, because of the way the eye sees color (and not due to the nature of the waves) many colors can be produced either by a  single wavelength of a combination of two or more wavelengths.  For additive color reproduction three primaries are selected (red, blue and green) because they produce the widest range of other colors (gamut), probably because of the way the eye works.  Other primaries can be used, but they will result in a more limited range; also more primaries can be added to increase gamut.  How selected primaries are combined to create other colors is shown in the "CIE color chart".

almost certainly it would be in the visible region of the spectrum. after all it does have that pretty color!\nvisible region is roughly between 400-700 nanometers wavelength.

The color of the sky and water has to do with optical physics. Light is scattered by tiny particles like dust. Scientists use waves to describe how light moves through space. These light waves have different lengths (wavelengths). Each different wavelength corresponds to a different color of light. White light is made up of all the different colors and wavelengths of light. It turns out that short wavelengths of light are scattered more easily by particles and dust. Blue light is the shortest wavelength of light visible to the human eye, or the visible wavelength that scatters easiest.\n\nA simple answer is blue light is more easily scattered than the other colors of light.\n\nDuring a beautiful sunset the sun appears closer to the earth, and the light travels thru more dust and other particles that scatter light better. This allows for the more difficult wavelngths of light like orange and red light to be scattered.\n\nYeh.

RED has got the highest frequency among the seven colors and VIOLET has the least frequency.\n\nThe formula for energy is \nEnergy = h * v  ( where v is a greek alphabet pronounced as 'nu'.I couldnt type that in my keyboard. Nu represents the frequency. h is the plank's constant)\n\nThus energy is maximum for the RED color. When energy is maximum it has the capacity to travel long distances and thus we are able to see it even for a distance.\n\nHope so u got what u wanted.

Someone else said the colors of the visible light spectrum. This is correct. That is an acronym used to help remember the order of the light wavelengths.\n\nThe longer wavelengths on the left (Starting w/ R.)w/ red being the longest and as you move toward the right the wavelengths are shorter w/ violet being the shortest.\n\n-------Red Orange Yellow Green Blue Indigo Violet-------\nLongest<--------->Shortest\n\nThe visible light spectrum is part of the electromagnetic spectrum. It makes up a small portion of the different wavelengths.\n\nOn the shorter wavelength end you have Ultraviolet radiation, x-rays, & gamma rays. With the longer wavelengths you have infrared, microwaves, & radio waves.\n\nThe shorter wavelength, the greater amount of energy it contains & the more potentially dangerous it is.\n\nSee EM Spectrum diagram using the link below.

You have it half right:\nBlack is the ABSENCE of all color, so it really couldn't be called a true color.\n\nWhite, however, is the presence of ALL colors (use a prism to see the rainbow of visible light), and therefore could be considered a color: all color.

C- longer wavelength.  Red is the long (low fequency) end of the spectrum, and violet is at the short end (high frequency).

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

The sky appears blue to us on a clear day, because the atoms of nitrogen and oxygen in the atmosphere separate the suns white light into its many colours, and scatter them throughout the atmosphere.The wavelength of the blue light scatters better than the rest, predominates over the other colours in the light spectrum, and makes the sky appear blue to us.The scientific name for this phenomenon is the Tyndall effect, more commonly known as Rayleigh scattering.\n\nThis phenomenon describes the way in which light physically scatters when it passes through particles in the earths atmosphere that are 1/10th in diameter of the color of the light. The light spectrum ranges in wavelength from red to violet, and, since the wavelength of the blue light passes through the particles with greater ease than the wavelengths of the other colors of light, the sky appear blue to the naked eye.\n\nThe human eye has three types of light receptors, known as cones, located in the retina. The cones are either considered to be red, or blue, or green, based upon their strong response to light at these wavelengths. As light stimulates these receptors, our vision translates the signals into the colors we see.\n\nWhen gazing at the sky, the red cones respond to the small amounts of red light scattered, and even less strongly to the orange and yellow wavelengths. Although green cones respond to yellow, their response to scattered green and green-blue wavelengths is stronger. Finally, colors near the strongly scattered blue wavelengths stimulate the blue receptors.\n\nIn short, the skylight stimulates the red and green cones almost equally, while stimulating the blue cones more strongly. For these reasons, our vision naturally adjusts as clearly as possible to separate colors.

visible light has wavelengths from 400 to 700 nm. Frequency is inversely proportional to wavelength. The longer the wavelength (lower frequency), up to 700nm, the closer the color will be to red. As wavelength decreases, the color will shift through orange, yellow, green, blue, to violet at 400 nm. See; the color spectrum (more info in linked wikipedia article)
