Has anyone done A/B testing to see which color or font scheme works best depending on the country? For instance, pastel colors (blue / green) tend to attract Indians, red attracts Chinese, and more neutral colors attract Americans. This is what we found on AnalyticBridge: our new color scheme (more neutral) attracts more Americans to sign up.
Do you know of any websites that are testing colors for geo-targeting? Do you think that one day, Google India will have different fonts and colors on the webpage (I'm not talking about the logo), than say Google Germany? Would geo-targeting based on color cause branding problems (brand dilution)?
