history: I love the color blue, is it a cross between any other colors?
knowledge: It lies between violet and green on the spectrum of visible light.
response: I don't know but it falls the middle of violet and green on the visible light spectrum.

Oh really? Does blue have any historical significance?
knowledge: The semi-precious stone lapis lazuli was used in ancient Egypt for jewellery and ornament and later, in The Renaissance, to make the pigment ultramarine, the most expensive of all pigments.
response: I'm not sure but the old Egyptians used lapis lazuli as jewelry and decorations.

Oh cool.  What else is good to know about the color blue?
knowledge: The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering.
response: Well, the blue color of the sky and sea is thanks to Rayleigh scattering.

Yeah how does that work? Do the particles only reflect blue light?
knowledge: Blue light consists of a loose, chemical composition burned in an open, hand-held hemispherical wooden cup, and so is more akin to the flashpan signals of the Admiral Nelson era than the modern, encased signal flares, often launched by mortar or rifle and suspended by parachute.
response: I don't know about that but flashpan signals from the era of Admiral Nelson had a blue color.

I have absolutely no iea what blue light flashpan signals are!
knowledge: Blue light is an archaic signal, the progenitor of modern pyrotechnic flares.
response: I can't explain it but another thing about blue light would be that it is the ancestor of flares.
