It depends on which pair of glasses you look through. Every animal cannot see the same wavelengths light. So, the sky is a different color depending on who is looking at it. The sky really isn't blue though, it's just the hue we as humans tend to see. The true color of the sky is the color you see at the time. If it is true to me now, it is nonetheless true.

Nick B: I think you are really onto something here! We keep getting all these "Y is ski blue?" questions on Yahoo Answers. There has got to be a reason for this. I'd always thought that it was simple laziness: People wouldn't type the question into the search box to see if it might have been asked before. Now I'm not so sure. I think that these are the people who normally see purple sky but occasionally their heads clear long enough that they see a blue sky - but for only a minute or two. Then its back to purple for them.
Once they have the blue vision they need to know why they saw the sky this way. So guess what? They rush home, fire up their computers, go to YA and type in the dreaded question!
To all you who have typed in this question 1600 times before: I apologize for my snide answers. I thought you were only lazy but now I realize you are visually handicapped and that there really is a reason for your question.

The sky is colorless, the light waves from the sun, refract (bend), when they come in contact with the atmosphere, portraying a blue image. If you see a deep purple, this is an indication that there is pollution in the air, such as sulfur oxides, carbon oxides, and nitrogen oxides. The light waves are again refracting, and portraying an image of purple due the adulterants in the stratosphere.

The sky is the color it seems to be because the shorter (blue) wavelengths of sunlight are more strongly scattered by the gas molecules in the high atmosphere. The even shorter ultraviolet wavelengths are also scattered, but humans can't perceive UV. In this sense, you are perfectly correct. The sky is more violet than it appears to human eyes.

If we were color blind, we wouldn't care if the sky was purple or not. Not like we could see that.

If everyone were colour blind then that would be the norm and those that saw other colors would be special.

If we were all color blind, there would be no such thing as colorblindness. Think about it.
