14: Colour.—Originally meant a "covering."  From root "celare" to cover or hide.  Also Occultare, to hide.
Symbology of colours.  The language of the prism, of which "the seven mother colours have each seven sons," that is to say, forty-nine shades or "sons" between the seven, which graduated tints are so many letters or alphabetical characters.  The language of colours has, therefore, fifty-six letters for the initiate.  Of these letters each septenary is absorbed by the mother colour as each of the seven mother colours is absorbed finally in the white ray, Divine Unity symbolised by these colours.
