What number does the white candle represent?

White represents 5 to 8 years old, blue represents 9 to 14 years old, pink represents 15 to 19 years old, red represents 20 to 26 years old, and yellow represents 27 to 35 years old. The custom of putting candles on birthday cakes can be traced back to ancient Greece and Rome. When the admirers of themis, the ancient Greek moon goddess, celebrated her birthday, they would put honey cakes with candles on the altar. Later, this custom gradually evolved into inserting burning candles on children's birthday cakes and adding the content of blowing out candles.
