Have you ever wondered what mix of colors you see when you are seeing blue?
Like what wavelengths we're seeing?
Yeah, the idea that we are looking at wavelengths and perceiving it as color is bizarre to me. I wonder what wavelengths we are actually seeing when we see blue.
Did you know other animals like the mantis shrimp can see something like 4 times the amount of wavelengths we can? Imaging a color you can't see!
Blue
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 colours; 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.
qualia" or "raw feels". There is something that it is like to feel pain, to see a familiar shade of blue, and so on. There are qualia involved in these mental events that seem particularly difficult to reduce to anything physical. David Chalmers explains this argument by stating that we could conceivably know all the objective information about something, such as the brain states and wavelengths of light involved with seeing the color red, but still not know something fundamental about the situation – what it is like to see
