    Seeing is to the eyes what hearing is to the ears. Just as you can hear sounds, tones, and voices that tell you about the world around you, seeing allows people to perceive light, shapes, colors, and movements. Imagine being able to ‘feel’ everything around you without touching it, from a distance. It’s like sensing the presence, shape, and texture of objects, but from afar and all at once. Colors, which are a significant aspect of vision, can be likened to different tones or pitches in sounds. Just as a high note feels different from a low note, different colors have their own ‘feel’ visually. Overall, seeing is a way of sensing and understanding the environment from a distance, much like how you can hear someone talking from the other side of a room

      There’s only one octave with the colors so it kind of seems more like flavors. It’s less of points along a line as it is like peanut butter vs jelly vs broccoli

        Why would you say there’s only one octave?

        Human audible frequencies are in the range of 20 Hz to 20 kHz, and are logarithmic.

        Human visible frequencies are in the range of 400 THz to 800 THz, and are linear.

        There’s far more available distinction to be made with color than with sound, it just doesn’t interfere the same way.

          An octave is a doubling of frequency. 400 to 800 THz is one octave. Color has one octave.

          The way you know that is you don’t experience redness when absorbing ultraviolet light, and you don’t experience blueness when absorbing inferred light.

          It doesn’t “loop around” like the A note does at 440 Hz, 880 Hz, etc.

          An octave is when a doubling of frequency leads to a new waveform that stimulates the same set of neurons as the frequency an octave below it.

            Ah. That makes sense. Something about the harmonics, though:

            Sound generates those harmonics because it’s physically vibrating sensors in our ear, so we get a 1 to 1 translation of the waveform. Light doesn’t, because it’s received by 4 different sensors that are sensitive at different ranges and in different phases. The reason we don’t experience “blueness” in the infrared spectrum is because our infrared sensors don’t know what “blue” is.
