If we had no eyes then we would be unaware of the existence of color. What if we are are missing an entire aspect of everything simply because we do not have the organ to detect it?

We wouldn't even know.

Edit: A lot of you are missing the point. I dont mean sight, that was just an example. Another example could be sound, if we were unable to hear then we would be unaware of what 'hearing' is. Something that is as important as sound could be completely unobserved and unexperienced by humans. There could be something that has nothing to do with sight at all. It is pretty hard to wrap your head around because you cant really think of anything like it.
