[citation][nom]sidran32[/nom]Look up. The sky is blue. No one claimed the sky was colored with blue dye. There is no "element blue". Color is only perceived by objects reflecting certain wavelengths of light. If the object (in this case, the sky) is reflecting blue wavelengths of light to our eyes, then it is effectively blue.Any attempt at saying otherwise is just spinning scientific facts and the claim outside of the context it was intended for in order to sound smart. You may be right, but it's moot, because nothing has been contradicted.[/citation]
lol, it is actually you who is trying to overcomplicate things to miss the point completely. I will respond to you and razor512 at the same time, mainly cause this is funny. I have no real hope you will see anything as scientific fact.
First off, color. It is true that color is perceived. Look at this definition.
1 a : a phenomenon of light (as red, brown, pink, or gray) or visual perception that enables one to differentiate otherwise identical objects b (1) : the aspect of the appearance of objects and light sources that may be described in terms of hue, lightness, and saturation for objects and hue, brightness, and saturation for light sources ; also : a specific combination of hue, saturation, and lightness or brightness (2) : a color other than and as contrasted with black, white, or gray
The fact that it is perceived does not mean it does not exist (at least not unless it is in a philosophical sense that has nothing to do with this argument). Also, Color is quantifiable. In other words, a red object is red. If two healthy human eyes look at this object, they will both see red. Just because a blind man cannot see the object does not mean that it is not red.
If you like to think of color as certain forms of electromagnetic energy perceived by our eyes, that works too. Doesn't change the fact it exists.
Yes, if you look up, the sky looks blue. However it is clear. Let me give you an example: If you hold a clear piece of glass up against a blue wall, the glass would appear blue. It is not, however; The glass is clear, letting the color pass through. The sky is the same way, clear in letting the blue light pass through. The sun's light is bent at the top of our atmosphere (making it blue), not in the sky as it passed through. Therefore, the sky is clear. The easy way to prove this is how I explained before. Even if you get in a U-2 that flies at 65,000 ft, you will still be able to look down and not see blue. Instead, you will see (or actually not see) the clear sky.
