THE EXTRAORDINARY COLOURS OF AUDEN DARE

Auden lives in a world where water is short and is ravaged by water wars.  Internally, he also struggles with the fact that he is completely color blind.  When his uncle mysteriously dies and leaves him cryptic messages and a poetry-reciting super-robot, Auden will need friends to help him uncover the mysteries of what his uncle was really doing and why the government is now chasing him.
