As you design your community online, consider asking your intended audience about colors and their culture. White is color of sadness in some countries. Green is taken in Western society to mean environmental consciousness. In China, a green hat could imply that a man’s wife is cheating on him.
A color culture chart with some of our cultures is included in a conference presentation on “Culturability: The Merging of Culture and Usability” by Wendy Barber and Albert Badre.
