According to most definitions, color is a phenomenon which depends on light and eye characteristicts.
The phenomenon is said to need physical objects to occur.
But are water drops 'physical objects' ? ( Items, certainly not)
Physical, yes.
Objects ?
Searches define water as an 'environment'.
At a loss.
Is there a site where this can be discussed?
Ps Same in the original language.

Would you say ice is an object or just a frozen environment?

Ice would be defined as frozen water... I'm afraid so.

Brackets
Ice

Frozen water

Not gaz, not plasma, liquid, but unmoving.

Color is a wavelength of radiation which humans can perceive, it doesn't depend on anything. That we can see it is incidental to the universe.

Thanks for the chat.
Sorry. Looks you do not like the question, as your 'reply' is out of the topic.
Topic is science and language, not chemistry or physics or earth science nor medicine.
Chat not over. It never began.

Look, the reply to admin is written with the time there is to do that, nothing else.
The thread about the universe is interesting but there is not time for everything, sorry.
Please, do not be offended. There was no offense intended.

Color is a wavelength of radiation which humans can perceive, it doesn't depend on anything.
In a dark room, with a table over which the experiment is made.
You watch in a box which insides are painted black, lid glued, only a small window coverered with cristal clear plastic on the large side, two holes stuffed with pipes in the small sides facing each others.
No dust or particles in the box, sealed tight from it by the lid.
You light on a flash light at one of the holes, in the general direction of the other hole, and a white cardboard target in front of the box, opposite of the flashlight, at the end of the course of light.
Inside the box, nothing but darkness is to be seen. Light invisible.
Outside, a small circle of light on the white cardboard.
Color still does not needs anything to be seen ?
Even visible light is 'invisible' to the eye if you remove the piece of cardboard...?

Thought experiments are cool, but this is light, not science or boxes nor thoughts. A great alien investigator once said that.

Color is a wavelength of radiation which humans can perceive, it doesn't depend on anything. That we can see it is incidental to the universe. The wavelength is the same, but the receptor may interpret differently. For example, the same wavelength which appears as red to a human may appear as gray to a dog. So yes, color is dependent on the receptor.

Dogs don't interpret the wavelengths differently, they perceive different wavelengths than us.

I didn't say the dog itself interprets anything. A dog without eyes is blind. I said it's receptors, its eyes, interpret and determine the color.
Color is an illusion if the same object is red to one eye and gray to another. Wavelengths exist whether or not there are creatures with eyes in the universe. But color is dependent on the eye which sees it.

Say, strickly speaking its not the point*, but what about color and photon ?
?
Pretty please ?
I might try and make a reply about what's universal and what's partial on the other thread, you know. True rethorics, not false.
(* Well, bump, the : is there any place to discuss this, please? Color, rainbows, objects, water, element)

Ps Same in the original language. But the water droplets that serve to refract the light to make what we see as a rainbow aren't producing the light or the color, are they? The wavelengths we see as 'color' were embedded in the white light created by the physical object that produced the light.
