What does the color of birthday candles mean?

Birthday Candles In many places in China, people like to light candles on their birthdays. In ancient times, birthday candles were larger in appearance than lighting candles, with red bodies and gold lettering. Such as "longevity". On birthdays, candles should be lit on both sides of the long table in front of Shoutang, and some gifts such as birthday peaches, noodles, cakes and axes should be placed on the long table. In modern life, candles are indispensable for birthday parties. Candles are not only red, but also become yellow, blue and other 12 colors, and their appearance is more exquisite. How many candles are inserted on the birthday cake according to the birthday person's age? Some people use one candle to represent 10 years old. After the candle is lit, if the birthday person can blow it out in one gulp, it means that his wish can come true. Yellow is dim, indicating 1 in the growing period, and blue indicates that middle-aged people are dark and strong, so it means 3.
