I have 3:
Black as black as a star-less sky at midnight, deep in the densest woods,
Royal purple where red makes it's point, but a midnight blue breathes it's chill, bringing it to sultry deepness. *BARELY* sweet, and so deep, no Merlot or Chiraz could ever compare.
And, the deepest dark of a blue which, by merely looking at it, is like jumping into the ocean in March while inhaling the mintiest of vapors that make every breath a near (but NOT!) numbing experience!
