Origin
誕生色 · Tanjoshoku
In Japan, a quiet tradition holds that the day you were born comes with a color. One that carries meaning, personality, and beauty.
Tanjoshoku (誕生色, literally "birth color") is a Japanese concept that assigns one unique color to each of the 366 days of the year, February 29th included. Each color has a name, a meaning, and a set of personality traits said to reflect people born on that day.
The system was popularized by the book 366色の誕生色 (366 Colors of Birth), which paired every date with traditional Japanese color names. Many drawn from nature, the seasons, and centuries-old dyeing traditions.
Unlike astrology or birthstones, Tanjoshoku is purely visual. A color that is, quite literally, yours.
