Broadcast Design for a series channel.
Because the channel was to host the darker array of series produced: ie Dexter, True Blood, Game of Thrones and the like, and because these shows always showed an underlying theme of the battle between good vs evil. STARK was born. A "STARK" contrast between: dark and light, black vs white, good vs bad... and of course the many shades of grey.
The channel imaging then would follow this theme throughout, with a few highlight colours to depict certain shows.
