The rainbow we all know it’s the color of yellow, red, orange, blue, green violet. ROYGBV. I’m keeping indigo out of mind because, let’s face it, is it indigo? What do you find violet? Is it near the end of this? What’s this dark blue? What’s this brighter blue-green? Cyan, perhaps? Then why not declare that the rainbow is red, orange, green, yellow, blue, and cyan? ROYGCB.
Actually, we do. And we’ve just forgotten. In the time that Isaac Newton originally observed a rainbow of light split up by prisms and then made his labels of the hues in terms of red, orange, blue, green, yellow, violet, and indigo. The blue he described was, in fact, what we today call blue-green, teal or the color cyan. It was reminiscent of blue skies, what we are now accustomed to calling blue. Newton called violet. That is, the roses are red violets are blue. Dark blue.
Indigo was only one of his seven primary shades of the rainbow in order to be in tune with the notes on the Western musical scale.
Magenta, purple, along with hot pink we’ve seen aren’t part of the rainbow when you look through a prism since they are only created by combining blue and red light. These are located on the opposite side of the rainbow and nowhere far from each other. There isn’t a single shade of hot pink or purple within the rainbow that is viewed from the prism. Violet is in the roses. They are red, while violets are blue sense. However, purple isn’t. Then why are rainbows appearing in the sky appear to contain purple?
I think it’s sometimes an optical illusion that makes lovely deep blues in tiny quantities surrounded by a lighter hue appear to be purplish to our eyes. Sometimes, however, the colours pink and purple appear since a rainbow is actually a rain disc. Every colour of sunlight bounces back to form a bright, edged disk in different sizes. These all add up to create a white disk with a bright edge.
Since it is the case that light waves, the raindrops’ interference creates numerous rings. The most familiar outer ring is only the most bright. The other rings are referred to as supernumerary rings. They are the cause of supernumerary rainbows. The smaller the size of the raindrops, the bigger they are. Supernumerary bows. If the raindrops are of the correct size, the red supernumerary ring could overlap with that of the violet one. What do both violet and red offer? Purple.
According to the old saying, “Roses are red,” violets are blue, and the colour purple in the form of a rainbow is an extraordinary hue.
