There is an infinite number of colors in a rainbow but we only see the seven colors (ROYGBIV). It comes down to the way our eyes function.
3 primary colors: red, yellow, and blue. 3 secondary colors: orange, green, and violet. 6 tertiary colors: red-orange, yellow-orange, yellow-green, blue-green, blue-violet, and red-violet.
Perhaps because there are so many different types, each with its own distinctive features, new research suggests. There are 12 types of rainbows, distinguished by various characteristics, the study suggests. Fat droplets of water or tiny sprays of mist will affect them, along with the angle of the sun.
The colours of the rainbow are: Red, orange, yellow, green, blue, indigo, violet. Can you find items from around the house in each of the seven colours?
We see our world in a huge variety of colour. However, there are other “colours” that our eyes can't see, beyond red and violet, they are: infrared and ultraviolet. Comparing these pictures, taken in these three “types of light”, the rainbow appears to extend far beyond the visible light.
Red-green and yellow-blue are the so-called "forbidden colors." Composed of pairs of hues whose light frequencies automatically cancel each other out in the human eye, they're supposed to be impossible to see simultaneously. The limitation results from the way we perceive color in the first place.
Indigo is omitted because few people can differentiate the wavelengths well enough to see it as a separate color. The six-color spectrum also fits the model of the color wheel, with red, yellow, and blue being primary colors.
Scientists have identified an invisible eighth colour in the rainbow, a discovery that could have wide-ranging implications on the nature of military camouflage and modern espionage.
A full rainbow is a complete circle — 360 degrees — but at best, we usually see only half of it.
Indigo is a rich color between blue and violet on the visible spectrum, it's a dark purplish blue.
One of the rarest forms is multiple, or double, rainbows. They occur when several rainbows form in the same place at the same time. It takes at least one primary rainbow to generate this sight, as well as several other secondary rainbows. There is always space in between each one.
Yes, although very rare, it is possible for a human to see four natural rainbows at once in the sky. A rainbow occurs when white sunlight scatters off of raindrops in the air.
Raymond Lee, a meteorologist at the US Naval Academy told National Geographic that true quadruple rainbows are extremely rare. 'There have only been four or five scientifically documented sightings of quaternary or tertiary rainbows since 1700,' said Lee.
It has been determined by people who determine such things that there are somewhere around 18 decillion varieties of colors available for your viewing enjoyment. That's an 18 followed by 33 zeros.
Different Colors available are: Red, Black, Blue, Green, White, Purple.

Though it's pretty difficult to actually see one, 360-degree rainbows are not actually rare. In its total form, a rainbow truly never ends. Our ground-based vantage prevents us from seeing the full, colorful circle of refracted light.

RGB Color Values
Each parameter (red, green, and blue) defines the intensity of the color with a value between 0 and 255. This means that there are 256 x 256 x 256 = 16777216 possible colors!
These are light vs dark, red vs green, and blue vs yellow.
Therefore, the colours 'blueish-yellow' and 'greenish-red' are the alleged “impossible” colours that we can't see.
Apparently not: turns out there are six colors that you can see that don't exist. Firstly, let's get it out of the way … technically, magenta doesn't exist. There's no wavelength of light that corresponds to that particular color; it's simply a construct of our brain of a color that is a combination of blue and red.
The way we see rainbows or moonbows depends on how light travels from the sun to the moon through individual raindrops to our eyes. If the droplets are too small, like in fog or mist, the colors are less able to separate completely and a white or gray fogbow will form.
When light is refracted by raindrops, it separates the white light out into the visible spectrum, meaning it is no longer white. Grey is a mix of black and white, and as we can't ever see black and white in a rainbow, we also can't see colours made by mixing them."
Yes, they exist and are also known as upside-down rainbow! Actually, reverse rainbows are not really rainbows, they are circumzenithal arcs. Circumzenithal arcs are like the halos you see around the sun or moon.
