Ok but it's a new experience that no one has had before. The only reason why the set of electromagnetic wavelengths is special is because it's part of the human experience. So seeing something outside of that normal perception is arguably seeing a new color.

Color is mostly a biological sensation. In low light, humans lose color acuity because rods are activated more than cones. Objects reflect the same wavelengths, but our cones can’t activate due to low energy. Does this mean color fades in low light? It depends on the physiology of the perceiver.

Humans have three color receptors peak-sensitive to red, green, and blue. Dogs have only two: yellow and blue. This means they can’t distinguish certain wavelengths. To dogs and colorblind humans, red and green look the same because their receptors are activated similarly. Color isn’t just a property of light; it’s a biological perceptual experience.

You say that, but Magenta is similar. It's a unique reaction in our perception to two different wavelengths of light combining. Magenta is not in the rainbow.

Objects don't "have" colors either, if we're being pedantic. They reflect/absorb/transmit/emit different combinations of wavelengths. So "pink" objects just reflect some wavelengths that we classify as in the range of "red" and "blue". Color is an interaction between emission, detection, and the brain's interpretation.

Its not even a unique trick. The ears combine various wavelengths of air vibrations to create sound, with combinations of pure waves merging into distinct timbres (sometimes called "tonal color").

Did you know we only experience pink as our red and blue cell receptors being stimulated at the same time? There is no pink wavelength.
