My favorite color is blue. I love it because it is  between violet and green on the spectrum of visible light.
Blue is a great colour. I consider to also be one of my favourites. Is it a prime colour?
Most time blue contains a slight mixture of other colors; azure contains some green, while ultramarine contains some violet.
That is amazing but is it one of the prime colours?
Maybe, the  clear daytime sky and the deep sea appear blue because of an optical effect that is called  Rayleigh scattering
Right. How do you think it rates against other colours. Do you think its one of the top most liked colour in the world?
Of course yes, it has  been an important colour in art and decoration since ancient times.
