What is the blackest black? Or the whitest white?
If it presented itself, alone, without comparison, could you specify what it was or what it wasn’t?
Is this one the purest form? (or the most legitimate? or the best, perhaps the worst?)
If you looked into its eyes, to its depth, could you judge, straight-faced, exactly what it was or wasn’t? Or would you err on the side of caution – on the side of odds and acceptance and total unexceptionality – and declare that it is probably a shade of grey or maybe beige.
