Oh wow, that greatly varies from locales to locales. Not only the color can be swapped depending on the locale, but the specific color can also change. For example the Korean locale (hl=ko) uses red for up (same to Japanese) but uses blue in place of red for down. Both languages have a single native word for blue-or-green or "grue" so either should work in principle, but I have no idea why Korean specifically uses blue. In my brief check there is only one more locale (Khmer, hl=km) where blue is used in place of green (for up in this case).
