i think 'black' should be removed from this poll as black isn't a true colour...
a quick google returned this...
In terms of Perception, Black like Greys and White, is an achromatic colour: a colour without hue and saturation (or "strength").
If the term is intended to be Physical (physical and psychophysical concepts are often confused) and Black refers to a total absence of visible radiation (light) then, if there is no physical stimulus, there can be no physiological response: no response-> no perception-> no colour.there... that should put the cat among the pigeons
ps. can we replace the black with the fjord blue... it might only get one vote but it would make me happy
tbh mate your blue is the better blue, looks lush, dont really like dark blue, too bland 
thanks chap - yep it does look lush in the right light... goes from light to dark blue and has a real wet look when clean!
