He loved numbers and also loved applying them to the phenomena of the real-world. This is because of the 6th century BC and an (in)famous philosopher named Pythagoras.
Or, for those in the western cultures have been so told. But then, how many divisions should there be? Ancient Greece and the magic of seven: Why Does The Rainbow Have 7 Colours? So here, Sir Newton decided that probably by breaking this spectrum into chunks we could easily talk about the divisions. For a rather surprising factor, it is not a distinct set of colors but a spectrum. In this visual spectrum, one can notice that each color bleeds into the neighboring color. Great! So how does Sir Isaac come into this? In the 17th century, he was one to realize that when a white light breaks apart and is looked through a prism or raindrops, it breaks into a visual colored light spectrum. However, colors that we see are in light waves are combined according to the mixing method that uses red, green, and green as primary colors.
Pigments are mixed using a well-known-understood-yet confusing subtractive method that uses red, blue, and yellow as primary colors. The Theory of Color is a bit more complicated than just stirring together the finger into paints, so let’s get started already! The visual spectrum – Why Does The Rainbow Have 7 Colours? OK, so who decides that now? And, why do they? Well, let’s just keep it short and say ‘Issac Newton. Now, the color Purple if we see is then divided amongst itself into the color Purple and blueish purple. Perhaps including the black and white paint that makes every other color imaginable concluding to be six basic colors. However, the teachers of elementary school tell us that there are three primary colors Red, Yellow, and Blue that when combined make three secondary colors Orange, Green, and Purple. The best way to remember the rainbow color order is by its acronym ‘VIBGYOR.’ As we know, the rainbow colors are seven in number: Violet, Indigo, Blue, Green, Yellow, Orange, and Red.
