The rainbow has seven colours, including red, orange, green, yellow, violet, blue, and indigo. The abbreviation “ROY G. BIV” serves as a hack to a reminder of the sequence of colors that make the rainbow.
However, finger painting in elementary school is a great way to learn it is possible to distinguish three main colors: blue, yellow, and red. These are combined to create three secondary colors – orange and green, as well as (plus or minus white and black paint) every other color you can imagine. These are six primary colours.
So in the rainbow, purple is subdivided into purple and more blue-ish-purple. Who were the bananas who took that decision?? What was the reason?
The short answer is Isaac Newton. and Ancient Greek philosophy. Um, what?

The Spectrum Of Vision
The theory of color is more complex than mixing the right-hand paints. Mixing pigments is done using the well-known but confusingly-named subtractive technique 1. which uses blue, red and yellow as the primary colors 2. However, we observe different colors in light waves. The light waves combine colors according to the additive mixing method that makes primary blue, red and green colors. three.
What does significance of Sir Isaac have a role to play? The 17th century was the time Sir Isaac was the one who realized that when we break down white light by using prisms (or rain drops), we are able to see the visible spectrum of light-coloured (otherwise called “the rainbow).
You can observe that every color is absorbed by its neighboring colors within the spectrum of visuals. It’s not an exclusive collection of colors, but rather it’s a spectrum 4. However, Newton thought we ought to divide this spectrum into pieces so it would be easier to discuss it. However, how many divisions could there be? …?
Antiquated Greece And The Wonder Of 7
Seven is a lucky number. That’s what people in Western culture have been told. Why is that? The roots of this relationship go back as far as the period of the 6th century BC and a man called Pythagoras five. Today, Pythagoras loved numbers. He was also a fan of applying numbers to the real world. He was credited with discovering that music notes (of seven) could be converted into mathematical equations. Furthermore, he believed that the celestial space bodies ( seven known in the early days) moved according to mathematical patterns.
Do you see patterns? Pythagoras did: his research proved the 7 to be a supernatural number that linked diverse phenomena. He also believed it was the total from the divine (3) and the physical (4).
Pythagoras also founded an institution with the same ideas that his followers embraced and grew into a philosophy known as Pythagoreanism, which was founded on mysticism and mathematics. Pythagoreanism was influential to some of the most famous classical thinkers, such as Aristotle as well as Plato.
So we have seven days in the week as well as seven subjects of the liberal arts, Seven deadly sins, seven marvels of our universe and seven dwarfs.

How Did It Come To Be Put To Use In The Rainbow?
The circular route takes you from Pythagoras to Newton.
It is believed that the Pythagorean philosopher Philolaus was the first person to propose that the Earth revolves around the “central flame” (rather than all things revolving in the Earth). The theory was later employed by Copernicus, who is acknowledged for developing the Heliocentric theory of the motion of the planets. Also, Newton used Copernicus his work in creating the gravity theory he had developed himself.
Newton Believed That His Pythagoreans Were Pretty Awesome
When he began his work using color, he initially did not subdivide his spectrum into five hues (red, yellow, blue-green, blue, and purple); however, he changed the color spectrum to seven by including indigo and orange due to Pythagoras’ belief there was a link between music and color. In addition, seven notes exist in nature, which means that it is also possible to have seven primary colors.
Music, math, numerology and even a few dead people. This, my friends, is why there are seven hues of the rainbow.
1. It’s called subtractive since it’s “subtracting” light when it is added color. The more colors you add to your mix, the darker the result. If you mix three colors, you’ll obtain black, which is light subtracted. This is a simple concept.
2. To make the situation even more complicated, If you’re talking about printing — which employs subtractive colour mixing, you identify the primary colours CMYK, which means cyan (a hue of blue) and magenta (which is reddish-ish, perhaps? ), yellow (okay, one of them is accessible) and black (which is called k because the “k” ey plate in a printer is filled with black ink).
3. Additive due to the fact that the light is added. When you mix all the shades (or wavelengths) of light, they will add to white.
4. If you want to know more, Wikipedia has a pretty sweet table of important spectral colors and their wavelengths.
5. Yup, the same guy who came up with the a2+b2=c2 right triangle theorem.
