The white color of the cloth represents purity. Rainbows are the biblical symbol of peace, happiness, goodness. The number of bands of the rainbow equal to the number of candles in the Menorah, one of the national religious Jewish symbols. The Menorah speaks of the creation of the world in seven days, and the number of bands of the rainbow emphasizes the connection with the ancient Jewish symbol. Also, the rainbow may symbolize the Seven Noahide laws. Rainbow flag controversy 

In 2013, the flag was checked according to the Russian gay propaganda law for the presence of "gay propaganda", because of its resemblance to the LGBT flag. The JAO flag was confirmed as safe because of its white background, white borders between the colored stripes, and the seventh (light blue) colour. However, there are gay-pride flags that use the seven colors of the JAO flag. See also
