history: My favourite colour is blue.
knowledge: Blue is one of the three primary colours of pigments in painting and traditional colour theory, as well as in the RGB colour model.
response: Cool, blue is one of the primary colors in the RGB color model.

Can you tell me anything cool about blue light?
knowledge: For instance, one can additively mix yellow and blue by shining yellow light together with blue light, which will result in not green but a white light.
response: Well, you may be interested to know that white light can be made when shining yellow and blue light together.

Whoa and not green? That's pretty cool, I also heard colors have temperatures, can you tell me anything about that?
knowledge: In practice, color temperature is meaningful only for light sources that do in fact correspond somewhat closely to the radiation of some black body, i.e., those on a line from reddish/orange via yellow and more or less white to blueish white; it does not make sense to speak of the color temperature of, e.g., a green or a purple light.
response: Well, color temperature is only meaningful if the light corresponds somewhat closely to some black body's radiation.

oh good, can you share  some details
knowledge: Color temperature is a characteristic of visible light that has important applications in lighting, photography, videography, publishing, manufacturing, astrophysics, horticulture, and other fields.
response: It is an important feature in photography, manufacturing and astrophysics.
