Growing up, I was taught that rainbows have 6 colors. Red, orange, yellow, green, blue, and purple. It makes sense as it goes from primary color (red) to secondary color (orange) back to primary (yellow) back to secondary (green), to primary (blue) and finally ending on secondary (purple). Indigo is a blend of blue and purple, but purple is a blend of red and blue…..

Newton was a nut and thought that the number 7 was some sort of mystical, inherently magical number that everything in the universe worked around. So he jammed an extra colour in there to make it up to 7. Things like infrared and ultraviolet would be added later as we discovered them.
Newton also thought that he could mathematically calculate the biblical apocalypse and tried his hand at alchemy trying to convert metals to gold etc.
