It was, by definition

Sure, it's a label

There is - they activate different receptors your brain relies on, hence leading to a distinct (from other wavelengths) sensation



The waves aren't inherently special, your retina is.

What if we were sensitive to the 200 to 500nm range? What would be blue, violet and red then?

Our eyes and brain are the one constructing what we perceive as color. It doesn't exists outside of us.
