I am not sure I understand this sentence, but can't resist: whatever you 
think of, we would not experience it as a colour, because a colour is 
what we see with our eyes which are sensitive of a few frequencies of 
light. Space is as coloured as Earth is, and the reason we would see 
space rather black and white than coloured is because our eyes evolved 
during sunshine, at least for the main part, our eyes therefore are not 
very sensitive in the dark. Space is overall too far away from suns for 
us to see colours. If you would take a flashlight to a planet you would 
see colours as on Earth.
That is also why pictures can be more coloured than what we see in the 
night, they can 'add up' the incoming photons, we can't, our eyes 
process them immediately. We can see colours in meteors because they can 
be just bright enough for our eyes. (This last remark is to be not too 
much off-topic :)
