Now that cable has moved into a streaming online service not much room left for TiVo. Commercials will reign again.

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.

You can call it whatever you want but color isn’t a physical property of light. It is a construction of the mind. You claim a certain wavelength is yellow. A computer display can show a combination of red and green pixels that we perceive to be the same shade of yellow even though the original yellow wavelength isn’t present at all. Color isn’t from the light itself but from our mind.

Colors aren’t physical. There is no way to measure color. We can measure frequency, wavelength, or energy. So there isn’t any light that is yellow at all. There is light, or combinations of light, that we perceive to be yellow but that is simply a construction of the mind.

Colors don’t actually exist physically. They are a creation of the mind.
