Applies to many other colors as well. I “understand” why that is but it hurts my brain to think about.

    Correct. You can’t measure yellow, you can only classify yellow.

    In the same way we classify all sorts of things. Types of planets. Types of animals. Races of people.

    But that doesn’t mean you can say there’s no such thing as yellow light. That’s like saying there’s no such thing as dogs because there’s no Internet dog property to measure.

    Semi-Subjective classification exists within science and within our language. It is a real thing. And so there IS such a thing as yellow light.

      The color yellow subjectively exists. Like I said at the beginning, color is a product of the mind. Objectively, as in is it directly measurable, light has no color. Physics deals with objective measurements.

        Objectively yellow is between 590 and 610nm.

        More bad news, there are displays that are RYGB, made by Sharp.
