We've been working with the KFC brand recently and it's been a real eye opener to see how out of control a big brand can get. In the past i've worked with some highly organised brand teams (visa and o2 are particular stellar examples) and you come to expect a certain level of control from organisations that operate on a global scale.
It seems with a KFC franchise there is no guidance offered for reproducing the logo or colours. We reverted to going in to a brand and collecting material to try and find the primary colour, but even that didn't get us very far.
People often joke about the 'brand police', but i really wish i could call them sometimes. in fact this might be something that i set up. maybe i'll get me one of those big red phones like in batman!
