Four stars for pulling off the absurdity, although it mellows out towards the end.
The story tells of the last four days of Eddie Russet's life before he's eaten by a carnivorous tree. He's a young lowly "red", only higher than a "grey" in the chromatic structure of his society because at least he can see *some* colour, and no one can see in full colour. The entire society is based on maintaining their colour hierarchy and acquiring artificial colour that everyone can see. So, very silly, but I found it amusing.
