Perhaps its a good thing that we didn't decide to waiver our Relocation Consultancy fees after all!! (Joke intended!!)
May I just add that, as I understand it, it is fine to refer to someone in the UK as "black" but highly frowned upon to refer to someone as a polite "coloured" person.
To the OP: I think you may have misread Rocky's post re the "lowly black" comment - suggest you scroll back and re-read before you consider how to apologise for your misinterpretation of what he said...
