What color is space?

You might think that the answer is black but I have something more to add to that answer. I definitely feel that Space is beyond 3 dimensional perception. We can see Space as an endless area of black but it does not have a proper explanation.

The prism experiment

We all have seen the prism experiment where the suns rays are allowed to fall on a prism at an angle and we see a band of seven colors on the other side. But scientists have found that these are the colors that only we can perceive. There are colors beyond violet that we call ultraviolet and red that we call infrared. These colors can only be sensed by temperature according to us. Space might be extremely colourful but we just cannot perceive it. Maybe its a color that some other organisms can see. 

According to physics we obtain the color black when there is no source of light. White is obtained from the mixture of the 7 colors that we see in the prism experiment. Doesn't the definition of the color black seem a bit incomplete. When there is nothing, black color is obtained seems just wrong. I believe there must be something that forms the color black.

This question popped up in my mind when I was studying about the spectrum fundamentals in physics. It was a long time ago but the question still remained.  The comments are open for your opinions. And as always.............
