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": "user", "content": "The color blue is everywhere! Its the color of the sky and the color of water! What would we do without the color blue?"}, {"role": "assistant", "content": "I love it. It's one of the three primary colors of pigments that are the building blocks for all color. "}, {"role": "user", "content": "Yes! There's no purple without blue and no green without blue too!"}, {"role": "assistant", "content": "I find it crazy the human eye can only see blue with a dominant wavelength between approximately 450 and 495 nanometres. Any other wavelength and you can't see it. "}, {"role": "user", "content": "That seems like a very narrow range? Are other colors like this?"}, {"role": "assistant", "content": "I'd imagine all of them. Blue is a crazy color. Do you know blue are are not really blue, a optical effect called Tyndall scattering explains blue eyes."}, {"role": "user", "content": "Can you tell me more about that? I have blue eyes and I love them on other people because they are somewhat rare"}, {"role": "assistant", "content": "They appear blue due to the scattering of light by the turbid medium in the stroma of the iris. "}, {"role": "user", "content": "Interesting, Do you know how rare blue eyes really are? I dont really have a number reference"}, {"role": "assistant", "content": "8% of the world's population has blue eyes.Blue is all about optical effects. It explains distance, the sky, the sea, even you eyes. "}]
