Why don't Belgians like blue?

Belgian taboo 13 and Friday. Think this is a symbol of disaster. They are most jealous of blue and regard blue as the color of the devil. Therefore, whenever something ominous happens, they always use blue as a sign. They also avoid dark green because it reminds them of Nazi uniforms.

Belgians generally don't wear green or blue clothes, and they hate people who wear these two colors. This is because Belgians believe that Nazi soldiers' clothes are dark green, while blue is mainly used as a sign of ominous things in Belgium and is regarded as the incarnation of the devil. Insisting on wearing these two colors will definitely remind people and make people unhappy. Navy blue uniforms or suits popular in various countries are absolutely hard to see in Belgium.
