Roses are red, the sky is blue...

Or are they?

Whist beginning my new self training into Lightroom editing a thought had occurred to me.
The old argument of if the sky is actually blue or if it's another perceivable color in the end is kind of irrelevant if your perception of any given color is only limited to the vocabulary used to describe it.

For instance a color blind person who can see the gamut of hues may perceive say red as what others would see as grey, but if from birth if the word that used to describe it is still red, then for all the color blind person knows (unless they do a test for it) is that IS red. 

So to say that the sky is blue could also be for some people inaccurate but the argument persists that unless we all see and use the same words for the same thing, there is room for anomalies in the argument. 

Oh, and the sky is Totally Purple!  :P
