As a client, I undertook market research for Coutts about 9 months ago for Silk and Black.

You will be disappointed (assuming they haven't changed much from feedback - and given the leaflets sent through, they haven't).

The Silk card has a Chinese street scene as the faded image on the card and nasty Orange typeface (like their diaries). The black card was grey/black with lines through it. Boxes/envelopes they came in were OK, but who cares.

Major missed opportunity not to have something classic and classy, but coming from the bank that thinks Stella and Boateng is what their customer base wants, it should be surprising.
