Writing everyday life: The color "Yellow"

Yellow! How was yellow born? Who decided to put it in the basic colors? What is the use that we can give to the color Yellow? Like my insurance said: Are you in good hands? yellow state!.
Yellow. . . well we can use yellow for many many things like, when we answer the phone we said: "Yellow! this is...." (at least that's what I say), or we put names to parks like yellow-stone Park, or we use it on traffic lights, or in fruits, or in the sky (we found it in the sun), or in people (no offense). We can even find it in other languages, like in Spanish yellow is the translation for ice!
Yellow has it own greatness, history, uses, applications, meanings and other reasons for existance. Like in Africa is the predominant color because we found the yellow in the sand of the dessert, in the Lion, the Tiger, on the Birds, on the sea for the coral. In other areas of the world we found it on the flags like China, Spain, Cambodia, Nepal. We can find it on the fruits, on the food (when the food gets rotten). Also we gonna find it on Mars in the near future.
Yellow is priceless in our lives. Because we see it every morning in the sun, every night in the sunset, every moment in our kitchen (unless you don't have any food), every form of life has some of the yellow itself.
Well, even when yellow is a big topic is hard to describe it, but anytime you see the sky, think on me and my yellow teeth (just kidding)... And never forget "Yellow, who is this!"
