But tha't not true. Black is the closest we come to experiencing colorlessness and black things are certainly not invisible. --- Also, water, i.e. H20, in a clean glass. Surely it's not _white_ as milk. We say, 'colourless', or 'uncoloured'. Oddly, while P. A. Stone mentions that some gases are ("for all practical purposes", he adds, somewhat otiosely -- I for one would welcome an 'unpractical purpose' -- call me anti-Utilitarian) colourless; water, when boiled _becomes_ colourful ('whitish' -- the white of the steam -- and similarly for melted water, or 'ice'). So, it's only in its liquid variety ('water') that H20 becomes truly colourless -- and hence 'free' -- but cfr. Vodka.
