Canadians told to "Exercise a high degree of caution in Germany"

The high degree of caution due to the threat of terrorism is also for France, UK, Spain, Belgium, Sweden, and also some non European countries.

The map in which the entirety of germany is yellow and the legend says that yellow means "exercise a high degree of caution" while the surrounding countries are gray, is awfully misleading. The map for france looks the same[1], with germany gray. The logic seems to be: This is the page for germany, the image only shows data about germany. In that case, other countries shouldn't be shown at all, rather then in gray.
