    How many colors does a rainbow have?

    If you ask a question to any counterclaim about how many colors a rainbow has, he will answer you straight away that the rainbow has seven colors. Where did this seven-color rainbow spectrum come from?

    This is the very rare case when the source is well known. Back in 1267, Roger Bacon explained the rainbow as the refraction of sunlight in raindrops. However, only Isaac Newton was able to analyze the light, breaking the rays through a prism.

    Why do we know from childhood that the rainbow has seven colors? Yes, according to the child-scorched child counting, in which the colors of the rainbow go in order. Here it is: "For each (red) hunter (orange), it is desirable (yellow) to know (green) where (blue) pheasant (blue) sits (purple)." In the modern interpretation, it sounds like this: "Every designer needs to know where Photoshop is being downloaded." There were also medieval rascalki. For example: "How once Jacques-ringer broke his head with a lantern".

    The perception of rainbow colors depends, oddly enough, on the culture of a particular people in a particular historical period. Russian people claim that the rainbow is seven-color. Americans with the British will prove to you that there are only six colors in the rainbow, since they have blue and cyan colors in one word. And there is no word, so no color. In the Australian aborigines, their Rainbow Serpent also had six colors, the same number in Congolese tribes, in which a rainbow was associated with six serpents. To some African tribes, a rainbow is generally represented with two colors — light and dark. The great Greek philosopher Aristotle singled out only three colors — red, green, and purple. He considered the remaining colors to be derived from these three main ones.

    Color perception depends on the thinking of the people. Thinking is based on culture, and culture is language dependent. And it turns out that the question of the “rainbow spectrum” has a more philological basis than a physical and biological one.
