Reflections

An image I made:

If what an object reflects, is the color it is, is it also colors it reflects that have already been reflected by other objects?
And something like a mirror, that almost reflects everything, does it count as being the colors of the objects seen in it?

Re: Reflections

Maybe he got reflected away from the forums or something

Anyway:

With the new technology being made with "invisible" suits, where there are cameras on one side of a piece of clothes/suit/shirt etc... and a video screen on the other side that shows what the camera is seeing, so when you look at someone, you see behind them. What will it look like in a room with mirrors as walls?

This.

Also, I don't really think he can prove this wrong. It's pretty simple and proven.

Re: Reflections

I'm not asking whether or not this is true, I'm asking whether or not something reflective, like a mirror, or an ipod, or something, "is actually the color that it reflects."

Two people can look into a mirror at the same position and see two entirely different colours.   I guess any specific point can be any combination of colours at any one time, including none.   Saying "the colour it reflects" is clearly an ambiguous thing.

Personally, I'd rather think of colour as what an object reflects in a majority when presented with all wavelengths.   If that's the case, then a mirror is white.   Its colour doesn't rely on what it's currently reflecting, it relies on the properties of the material.

Edit:
However, I don't know a thing about what colour truly is and how it's defined, so don't give any value to my words.

Well, the property of the material is purely to reflect when polished. If you were to look at a rough side, then yes, its color would be white, as you say. When polished that is eliminated and it is made to reflect whatever light hits it.

Similarly, you are able to see your reflection in water when it is still. The color of the water in that spot is the color of yourself, but when disturbed, the water becomes rough and loses its ability to reflect, thus making it adhere to the color of its properties. Therefore it is safe to say that it has multiple colors, nonetheless at different times.

EDIT: I'm talking about a mirror in the first paragraph.

I agree with this. If you have something that reflects both blue and green, but it only has blue light, you only see it as blue. But it still is blue-green.

If it reflects both blue and green light it is going to be blue-green...why would you only see it as blue? If it were exposed to more blue light than green light, yeah, it would seem more blue, but that is different.

EDIT: I now see what he meant, nvm.

Re: Reflections

:/ I specifically said there that IF it has only blue light on it it appears blue.

OOOOHHHHH, I see what you meant in that post now. Sorry, I guess I kinda skipped over those two words or something. Actually I think I just thought you were being stupid. Sorry.

I'll edit the above post.
