Adbusters is holding a competition for an anti-nationalist flag. This made me consider the psychology of color: the obvious choice among the contenders is a black flag with a simple white ring. Would it be flown in conjunction with the sky blue field of the United Nations banner? Blue appears to be the most popular flag color, with red a close second. "Interview suits" are conventionally blue: it is assertive without violence, bold and certain, calm but strong.
