The song is inspired by the breath-taking natural phenomen of the alpenglow (adaptation of the German word Alpenglühen; enrosadira is the Italian/Ladin word for it).

Alpenglow is an optical phenomenon that appears as a horizontal reddish glow on mountains such as the Italian Dolomites near the horizon opposite of the Sun when the solar disk is just below the horizon.
Since the Sun is below the horizon, there is no direct path for the sunlight to reach the mountain. Unlike sunrise or sunset, the light that causes alpenglow is reflected off airborne precipitation, ice crystals, or particulates in the lower atmosphere. The term is generally confused to be any sunrise or sunset light reflected off the mountains or clouds, but true alpenglow is not direct sunlight and is only visible after sunset or before sunrise.

The phenomenon may appear significantly different throughout the year; these variations in colour and duration are due to different atmospheric conditions or the different positions assumed by the Sun.
