The first recorded use of "light blue" as a color term in English is in the year 1915.
In Russian and some other languages, there is no single word for blue, but rather different words for light blue (голубой, goluboy) and dark blue (синий, siniy). The ancient Greek word for a light blue, glaukos, also could mean light green, gray, or yellow. In Modern Hebrew, light blue, Tchelet (תכלת) is differentiated from dark blue, Kachol (כחול).

- In modern Western culture, the color light blue is commonly used to represent boys as opposed to the color pink which is used to represent girls (but see the counterexamples at List of historical sources for pink and blue as gender signifiers).
- The color light blue is commonly regarded as calming and relaxing. Because of this, sometimes it is used to paint hospital rooms.

- King Louis IX of France, better known as Saint Louis (1214–1270), became the first King of France to regularly dress in blue. This was copied by other nobles. Paintings of the mythical King Arthur began to show him dressed in blue. The coat of arms of the Kings of France became an azure or light blue shield, sprinkled with golden fleur-de-lis or lilies. Blue had come from obscurity to become the royal color.
