In the 19th century, the colour was often used for military uniforms and fashion.

Surveys in the US and Europe show that blue is the color most commonly associated with harmony, faithfulness, confidence, distance, infinity, the imagination, cold, and occasionally with sadness.^[3] In US and European public opinion polls it is the most popular color, chosen by almost half of both men and women as their favorite color.^[4] The same surveys also showed that blue was the color most associated with the masculine, just ahead of black, and was also the color most associated with intelligence, knowledge, calm, and concentration.^[3]
