I agree, I have seen Navy blacker than black and only under bright daylight and close inspection does the simmering hue of blue show through. In a typical room environment normally lit, even a detailed look could reveal midnight navy as black. It is no big deal if the seller called a very dark navy black, it is an honest mistake. The buyer should either return the item and get a refund or keep quiet over the mistake and leave the seller some good feedback. There is no point sending seller a complaint and then keep the tie with a neutral feedback or try and bargain a partial refund. I wanted a black suit and got sent an extremely dark navy suit that was darker than my to go black suit. Knowing that the seller could not have told the difference between the shades, I let it go figuring I got roughly what I wanted in the end. All's well that end's well.
