history: My favorite color is blue. Interesting. Did you know that it is a primary color in the RGB model? I did not. I am trying to recall, where does blue fall on the spectrum of visible light It is right between violet and green What is another interesting fact about the color blue? Well with blue  The eye perceives blue when observing light with a dominant wavelength between 450 and 495 nanpmetres. Wow, that is way above my head. When I think of colors, I basically just think of what I can see, but its crazy there are a lot more to it then '' hey, there is the color blue''
knowledge: Most blues contain a slight mixture of other colors; azure contains some green, while ultramarine contains some violet.
