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!
That is pretty crazy to think about. I wonder if the mantis shrimp sees more colors in between colors. Like, blue is between violet and green on the spectrum. I wonder what the mantis sees between blue and violet.

Because blue has commonly been associated with harmony, it was chosen as the colour of the flags of the United Nations and the European Union.

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
