How do you get blue?
Blue is a primary light colour so it exists all the time. You cannot make it from any other colour. Shine a bright white light through a prism or look at a rainbow, you can see the "blue" part of the visible spectrum. Shine a light through a "blue" filter you can see the blue colour on a substrate. Between 400 and 500 nano meters frequency is where blue can be found
