My favorite color is blue, is one of the three primary colours of pigments in painting and traditional colour theory, as well as in the RGB  you any?
Blue is one of my favorite too! I don't know much about it though. 
Blue is  between violet and green on the spectrum of visible light
Interesting, what else can you tell me?
More so , eye perceives blue when observing light with a dominant wavelength between approximately 450 and 495 nanometres.
That's cool so light is essentially waves? 
blues contain a slight mixture of other colors; azure contains some green, while ultramarine contains some violet.
What is ultramarine? I've never heard of that.
