like as a physical property. i don’t know any color-ology maybe there’s a simple way to make me get it but
IT SEEMS like color depends entirely on BRIGHTNESS so an OBJECT can’t have a fixed COLOR because BRIGHTNESS changes all the time!
“Colour” is britbong bourgeoisie decadence colorblind leftists like me are the only ones with a chance of being free thinkers and the “one true leftist” :markkks-juggalo:
my eyes are a pretty unique color but a side effect is i cannot perceive most ‘mixed’ colors like at all
is that dark red or is it dark gray or brown? i will never know
plus side is i can see even in the darkest of rooms and nights. i once got lost in a forest as a kid with a bunch of other kids and they didnt have flashlights but i totally saved our asses cause i could see perfectly :gigachad: one almost stepped on a snake and i grabbed him lol
big downside is that i feel the need to wear sunglasses all the time cause the light burns us
i sometimes feel the need to wear them indoors lmao, those bright office lights got me all :squirtle-jam:
The electromagnetic field is a thing that exists everywhere and can be disturbed, creating waves (photons) that travel throughout space. Think of how you can disturb a perfectly still body of water to send waves to whatever direction. Waves are simply a way to transfer energy through a body (mechanical waves) or through space (electromagnetic waves). The light from the sun, for example, is just energy released through photons as a byproduct of nuclear fusion that occurs in its core. Photons always move at the speed of light, but you can have a source of photons release them in a difference frequencies. Radio waves, visible light, your wi-fi connection, the x-rays you take when you visit the doctor, are all electromagnetic waves being released in different frequencies.
Therefore, light waves are just disturbances in the EM field, and “Sight” is basically the mechanism that life on earth obtained, through evolution, to be able to perceive and detect these disturbances. We can’t, however, detect the whole spectrum of EM frequencies, just a small part of it. All colors are simply light waves of different frequencies, humans can perceive them from violet to red, and nothing else. We like to call “infra-red” and “ultra-violet” waves as invisible light because our eyes can’t detect them. Some animals, however, can. Ever heard of the mantis shrimp, which are said to be able to “see” way more colors than us? Their eyes are simply able to perceive a wider range of EM wave frequencies.
Does COLOR exist? It’s a human concept invented to give name to the different feeling we get when one of our senses is stimulated by a wide array of different light wave frequencies. Does SOUND exist? It’s also a form of wave, just a mechanical one. Energy can be transferred through air in the form of waves, the air vibrates which makes our cochlea also vibrate inside our ears. The different pitchness of sound is the way we can sense different frequencies of sound waves. All of these things “exist” in the sense that they’re ways our brain interprets the signals sent by other organs responsible for our senses. They’re just how we managed to find a way to sense the world around us.
Light can be thought of as waves of the electric and magnetic fields, much like waves on the surface of water. Color is related to how fast the wave oscillates, its frequency, which in our water example corresponds to how close the peaks of the wave are to each other. Brightness is related to how high the waves are, and is independent of the frequency.
Now color of an object is a bit more complicated. If you shine only blue light on a red object, it won’t look red. I would say the color of an object is determined by the frequencies of light that leave from it when it is hit by white light (light that has the whole visible spectrum of colors so it looks white), but that is not the only way to see things. You could just as well say that the color of an object changes depending on the color of the light hitting it.
it’s the wavelength of the photons that bounce off the surface of a thing, after some wavelengths have been absorbed. so like, green things aren’t ‘green’, the stuff they are made of reflects green. so no, ‘colour’ is not a physical property, but an emergent one on how light and matter interact which is dependant on a lot of things like brightness and the medium the light travels through and all sorts. and even then, the actual colour spectrum you and I see is entirely constructed by our brains and specifically how the human brain compiles that sensory information as something you and I understand
