Whilst i realize that I said my original logo has a black background (It is identical to your No.3 design only with a white stripe). I am concerned that with the black background it is a bit heavy/dark on say letterheads for invoices/quotes etc.
Was wondering if a grey or green or white background might come up with a different rebranding. I like the grey and green on the symbol for entry eleven - also the F&C symbol on entry 1.
