Because "color" is an interaction between the visible light portion of the electromagnetic spectrum and the light sensitive parts of our eyes.
Our eyes have evolved 4 different receptors--one each for Red, Green and Blue and another for violet.
A rainbow actually contains millions of colors, but we have evolved to categorize most of the wavelengths in the visible spectrum as one of the primary colors and their combinations.
the reason of getting seven colors in rainbow is because of the white light,
white light is made up of seven colors so when it is split by some water droplets it forms a seven color rainbow....
Because a rainbow is made from rain drops and so when light goes through the water drop the seven colours come out and it is seven because those colours make up white but this does not work with paint but it does with light so this is why rainbows have 7 colours
A rainbow has 7 colors because of the way that the water droplets break the sunlight. The droplets break the sunlight into all of the colors of the spectrum. There are seven colors in the spectrum.
Visible light is made up of light of many wavelengths, from about 400 nanometres to about 700 nanometres. A rainbow acts as a prism, splitting light into its component colours. We normally number seven colours in a rainbow, but of course, as you look at a rainbow, you see each colour shading into the next, so there are hundreds or thousands of colours in a rainbow.
If the question is why seven colours and not twelve (or any other number) the answer lies with Sir Isaac newton. Newton was a great believer in significant or spiritual numbering of things. In his understanding seven was a significant number. However a viewing of the spectrum shows six obvious colours (red, orange, yellow, green, blue and violet). Newton knew this "couldn't" be right and inserted indigo between blue and violet to make it seven.In reality there are a gradients of colours between each of the adjacent obvious colour and the rainbow could easily have many individual hues.
Many modern rainbows are shown with only six colours.
the Rainbow is 7 colours because of the light spectrums of indogo
Those are the colors of the spectrum of sunlight. Red, orange, yellow, green, blue, indigo, violet.
Because there are seven colors in the light spectrum.

Good question! There are seven main colours of a rainbow, but where they intercept, you get a range of thousands of colours, some beyond our capability of measuring.
There are seven colors in the rainbow, and "seven" has five letters. ROY G BIV is the traditional mnemonic for the colors of the rainbow.

There's no "why", because there aren't. Every possible color that anybody ever saw is in the rainbow.
