It’s pretty revealing that the gay rainbow flag has only SIX colors. Six - the number of man, a fallen creature. The best example is use of the number 666 in Revelation.
However, God’s rainbow revealed after the flood, has seven colors. Seven in the Bible is the number of completion and perfection, such as God creating the earth in seven days or the seven churches mentioned in Revelation. The seven colors in the rainbow also reflect God’s promise never to flood the earth again.
What color do they leave out?
the original flag had 8 colors, but 2 were removed for production purpose :) each color has a meaning, its actually quite interesting!
