Why does a rainbow have 7 colors if the three primary colors of light are red blue and green?
A rainbow has a smooth spectrum of changing color, with no objective division between one color and the next.
Different languages not only have different words that represent the different colors, but also divide the spectrum up into more or fewer colors.
Traditionally English-speaking people divide the spectrum visible in a rainbow into 7 colors, perhaps because the highly influential Isaac newton thought there was something special about the number 7 (there were 7 known planets at the time, 7 days in a week, 7 musical nodes in a diatonic scale, etc.),
so he deliberately divided the spectrum into 7 colors: red, orange, yellow, green, blue, indigo, and violet.
There are several other popular ways to divide the spectrum up into more or fewer colors.
