It’s not that easy being green, when I think it would be nicer being red, or yellow, or something much more colorful than that, even in a blue world alone. Certainly, most political parties agree even about green when choosing colors, as well as symbols, rosettes, and ties, officially or informally, to represent them or their point of view. Colors are part of the identity of parties, or of ways of life, as lavender and pink often refer to homosexuality, or gold to capitalism, or orange to Christian democracy, red to leftism and revolution, or blue to conservatism, except in American politics, or green for environmentalism, or black for fascist or Nazi policies, and now for ISIS. Shifts in color used by a party may reflect changes in policy. Some colors may be avoided: no party, for fear of being considered dull, is likely to adopt gray.
