This coloration, which can range from off-white to blood-red, is explained by the filtration by the Earth’s atmosphere of the sunlight that illuminates the Moon.
But the pink moon is simply the legacy of the English expression “pink moon”, which designates the first full moon of spring. However, right at this time of year, around Easter, the first flowers in the United States come out, phloxes, pink in color.
The spring moon is also called “redhead”. And not just because it can turn orange, which can happen any time of the year. After Easter, the red moon means a cloudless night, conducive to night frosts that can scorch the young shoots of plants.
