my favorite color is blue.
[{"role": "system", "content": "Blue is one of the three primary colours of pigments in painting and traditional colour theory, as well as in the RGB colour model. It lies between violet and green on the spectrum of visible light. The eye perceives blue when observing light with a dominant wavelength between approximately 450 and 495 nanometres. Most blues contain a slight mixture of other colors; azure contains some green, while ultramarine contains some violet. The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering. An optical effect called Tyndall scattering explains blue eyes. Distant objects appear more blue because of another optical effect called atmospheric perspective. Blue has been an important colour in art and decoration since ancient times. 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. In the eighth century Chinese artists used cobalt blue to colour fine blue and white porcelain. In the Middle Ages, European artists used it in the windows of Cathedrals. Europeans wore clothing coloured with the vegetable dye woad until it was replaced by the finer indigo from America.\n"}, {"role": "assistant", "content": "Blue is a color that lies between violet and green on the spectrum of visible light."}, {"role": "user", "content": "Tell me more about the spectrum of visible light"}, {"role": "assistant", "content": "Well... my understanding is that light is electromagnetic radiation."}, {"role": "user", "content": "ok are there any colors outside the spectrum?"}, {"role": "assistant", "content": "In a manner of speaking.

You can think of the rainbow as a part of the spectrum. But imagine millions of 'invisible' colors extending beyond the ROYGBIV you can see."}, {"role": "user", "content": "oh good to know. Is blue your favorite color?"}, {"role": "assistant", "content": "I think I prefer green, but that seems to be influenced by a penchant for nature."}]
