After joining the team at Philadelphia City Council as the first Art Director on staff, I redesigned Council's logo and created a helpful style/identity/brand piece to help with the transition.
I've found from design identity/brand standards, from large firms and small, that you cannot legislate what people think is a good idea. You must create a consensus by example. Make the design studio's work flawless, impactful and impressive.
Even got to "invent" a color. We call our orange "Creamsicle Orange". 'Cause we can.
