Color and Light

[Lost Ghost]

Because color is only represented by the way our eye preceieves it, if a red cup is in a completely dark room that you are in, what color is it?

I think...

We just went over this in another thread...Peep the thread about Time in our minds, and lets reask this question, mmmkay..?

[Lost Ghost]

But it's not some theortical bs like "if a tree falls and no one is around to hear it does it make a sound?" because of course it makes a sound, sound isnt the way your hear percieves it, its a common thing among everyone, people aren't born not being able to hear a tree falling, however some people are born not being able to see colors, or certain shades of colors, it was more literal and scientific then "oh lets ask a dumb question taht everyone thinks about forever"

Well, of course it's theoretical...There is no other way to approach it...But I can see where you may feel that this is different than the sound thread, so lets explore it...

QUOTE(Lost Ghost)people aren't born not being able to hear a tree falling

People are in fact born deaf, unless you meant something else...

But anyway, literally speaking, sight and perception are based on light and reflections that produce colors and hues in the objects we see...In a completely dark room that you may be able to reproduce at home, that place is still not completely void of light, it just is no longer visible to the naked eye...Unless I'm missing something......

Why would that object loose it's color value simply because you can't see the light acting on it..?

Sounds like,

Why would the tree not make a sound simply because you're not there to hear it..?

LG, I think if you're asking for a more scientific approach to this then yeah, AYHJA is right. Just like sound, color travels in waves...well, light, really, travels in waves. The colors you see are the colors you, personally, are equipped to see and not everyone will see the exact same hue you are seeing from a particular object.. The sun, specifically is responsible for the electromagnetic band we "see" and what we CAN see depends on the temperature of the source of said band...etc, etc....whatever.

your eye is equipped with both cones and rods (both receptors for wavelenghts). Rods transmit mostly blacks and whites, while cones take care of the rest, (well...mostly "warmer" tones, rather than "cooler" variations like blues and violets). We are able to see the wavelenghts that are not absorbed by the object, but the energy bouncing off of it.

QUOTEBirds, fish and many other mammals perceive the full spectrum. Some insects, especially bees, can see ultraviolet colors invisible to the human eye. In fact, color camouflage, one of nature's favorite survival mechanisms, depends on the ability of the predator to distinguish colors. The predator is expected to be fooled by the color matching of the prey. Until recently, it was thought that dogs didn't see any color at all. Recent studies now show, however, that dogs can differentiate between red and blue and can even pick out subtle differences in shades of blue and violet.


QUOTEColor is light and light is energy. Scientists have found that actual physiological changes take place in human beings when they are exposed to certain colors. Colors can stimulate, excite, depress, tranquilize, increase appetite and create a feeling of warmth or coolness. This is known as chromodynamics.

If a red cup it's in a dark room, the cup doesn't stop being red.
Maybe you see it as a very dark red, even you can say it's deep blue or black no matter how tricky lights effects are applied to the object.
The thing is that the object property of refusing the red part of the spectrum is still there.
So you might be shure about the colour and all the people with you agree, but it doesnt change the truth of its red colour.

if the wavelenght changes, the "signal" changes, so does its color. LG, if you're asking about its properties, no, it won't change (besides getting maybe cooler). If you're question refers to your perception, then yes, the color will change.

^agreed

[Lost Ghost]

But color in its property is perception, at least thats what my understanding was, thats why I thought this question was a little different.

I meant more along the lines of, people aren't born being able to hear everything else, but not hearing that, which now I even forgot why I mentioned it in the first place.

Blah this is probably another dumb question, I was just wondering, because color has no definition it is perception of the eye, so when the perception is forcibally squewed....then is the property of color as well?

No such thing as a dumb question M8, I love discussing topics, even if I feel I know the answer or not already...But, for future reference...If one of your threads is ever met with the infamous

...

Then that shit was really dumb, LoL...

You need to factor light into your last question, which should answer it nicely then...
