Rainbow

RAINBOW - The rainbow represents Gods fulfillment of a promise.  

(KJV Gen 9:12-16) -  And God said, This is the token of the covenant which I make between me and you and every living creature that is with you, for perpetual generations:

13 I do set my bow in the cloud, and it shall be for a token of a covenant between me and the earth.

14 And it shall come to pass, when I bring a cloud over the earth, that the bow shall be seen in the cloud:

15 And I will remember my covenant, which is between me and you and every living creature of all flesh; and the waters shall no more become a flood to destroy all flesh.

16 And the bow shall be in the cloud; and I will look upon it, that I may remember the everlasting covenant between God and every living creature of all flesh that is upon the earth.

NOTE:  Beginning in 1978 a rainbow flag, commonly the gay pride flag and LGBT pride flag, is a symbol of lesbian, gay, bisexual, and transgender (LGBT) pride and LGBT social movements.  (Other uses of rainbow flags include a symbol of peace.)   The colors reflect the diversity of the LGBT community, and the flag is often used as a symbol of gay pride when it comes to LGBTQ+ rights marches.   It originated in Northern California, but is now used worldwide.  Designed by San Francisco artist Gilbert Baker in 1978, the design has undergone several revisions to first remove then re-add colors due to widely available fabrics.   As of 2008, the most common variant consists of six stripes, with the colors red, orange, yellow, green, blue, and violet. The flag is commonly flown horizontally, with the red stripe on top, as it would be in a natural rainbow.
