How does agard use vivid imagery and amusing comparison in his poem to focus the readers mind on his message about racial identity?

When we look at John Agard’s poem, “Half-Caste,” we see quite a bit of vivid descriptions.  Agard uses imagery that is easily understandable to a majority of readers.  For instance, Agard describes mixing the colors red and green.  He describes the weather by mentioning how clouds overcast the sun, and he also describes music—the white and black keys on a piano.  These are all images with which most readers would be familiar.  These images are all presented in comparison to a person who is termed “half-caste.”  Of course, it is humorous to compare a person to paint, clouds, or piano keys.  Agard does this in an attempt to show the absurdity characterizing a human in the same manner in which one would characterize art, the weather, or music.
