Where The Buttercups Bloom

In a land ruled by colors and mutation, a violent struggle of power wars. The lower your color, the darker it is- the more mutated you are, some more physical than others. Having no color at all, or defying your color is punishable by death. Being born with a lighter color, a brighter one- the closer to perfection you are. Two colors though, White and Gold war together, the colors of Royalty, one won through bloodshed and murder, the one born into it. If a world is cloaked in simple beauty, seemingly okay, does it become the Buttercup? Lovely, but disturbingly toxic?
