Puke. Puke derives from the word "puke" which means puke. Puke can come in different colors, mostly green.
Let's be serious, who have tasted puke, I saw a pack of jellybean which a color can be two flavor, for example, a red jellybean can be a strawberry flavored, or centipede, brown for chocolate, or dog food. Tasted the green one, hoped it was a green apple flavor but, it was puke.
