How many colours does rainbow have?

Question

I heard that rainbow does not have only 7 colours. It has more than 7 colours!

Answer 1

Too many to count. The traditional description of the rainbow is that it is made up of seven colors - red, orange, yellow, green, blue, indigo, and violet. Actually, the rainbow is a whole continuum of colors from red to violet and even beyond the colors that the eye can see.

How Many Colours In Rainbow

Answer 3

A rainbow has an infinite amount of colours. It ranges through the entire visible light spectrum. People only typically name 7 of them, though. ROY G BIV. Red Orange Yellow Green Blue Indigo and Violet. However, there are not fixed transitions between these colours, they slowly fade into them so there are combinations of adjacent colours and you can't possibly name every possible combination!

Answer 6

A rainbow is comparable to a prism... A prism separates white light into a group of SEVEN colors called a spectrum. These seven colors are always in the same order. The colors of the spectrum are red, orange, yellow, green, blue, indigo, and violet.

Answer 7

Please note that BOTH answers are correct. There are seven "canonical" colors. R O Y G B I V . Many people, however, do not perceive indigo as a separate color from blue or violet, so that makes it six... Six or Seven are both "normally acceptable answers."



But as many of the OTHER posters have said, the edges of those canonical colors fade together. You get reddish-orange and orangish red and so forth. there's no sharp line where you can say "THIS IS RED and THAT IS ORANGE" although there are clear "bands of color" So, in another sense the answer is "an infinite number, since ever different wavelength of light is a color, and all the colors in the sun are there."



BUT BUT BUT BUT



The answer is _not_ "all the colors there are" because color perception is a function not only of wavelength but of saturation.



So, something that is of color blue, but very very dim, looks different than something the same color of blue, but very very bright. Also, some of our color perception comes from MIXING colors, and the rainbow UNMIXES them.



To put that another way, there is no "Purple with a greenish cast" in the rainbow. Neither is there "blue with a hint of yellow." The colors are all separated out.



So, the answer is 'Usually seven, but six for some people, but you can argue for an infinite number as they fade together."



Good luck

Answer 8

Color is a subjective term really, what you call sky blue,someone else might call baby blue. In scientific terms, when you see a rainbow , you are seeing the entire spectrum of visible light from red to violet. There is no hard cutover from red to orange, instead it is a constant fade from red to oragne to yellow etc.. with all possible colors in between.
