Slightly Depressed Rainbows are very rare but a sight to see. Unlike a regular rainbow which has the colors Red, Orange, Yellow, Green, Blue, Indigo, and Violet; a slightly depressed rainbow has the colors Black, Blood Red, Pale Blue, Faded Yellow, Dark Turquoise, Gray, and Light Brown. Unlike a fully depressed rainbow, which is all black, a slightly depressed rainbow is a little bit happier. A regular rainbow uses the acronym ROYGBIV, a slightly depressed one uses the acronym BRBPBFYDTGLB which has been deemed a pronounceable acronym by the National Acronym Association. Speech expert Mark Stewart says it should be pronounced Brebpebfuhyeedtiggleba. If you see a slightly depressed rainbow, give him a cookie, he won't be as depressed anymore.
