Showerthoughts@lemmy.world•Your display contains no yellow pixels - yet it displays the color yellow just fine
1·21 days agoI’m a physicist and no, color is not a physical property of light. Color is a subjective experience created by our mind in response to electrical signals from our eyes.

1·22 days agoThe 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.

1·22 days agoYou 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.

21·22 days agoColors 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.

2·22 days agoColors don’t actually exist physically. They are a creation of the mind.

I don’t see how a RYGB monitor is bad news.
How does one objectively measure color?
If color is in light then why do people see yellow from an RGB monitor when no yellow light is present? If color is a physical property of light how do we see color? Do the chemicals in our cones see/respond to color? How? How is color detected by chemicals in our eye transmitted to the brain? Does electricity also support color? If so, how?
