As a substance that primarily nourishes young animals, milk symbolizes the immaturity and passivity of the people who habitually drink it at the Korova Milkbar. Their drinking of milk suggests the infantilization and subsequent helplessness of the State’s citizens.

The only time the chaplain wears white is during an exchange with Alex, where the chaplain gets Alex to snitch on his fellow prisoners in order to further his own career ambitions. Lightness represents the demystification of the individual.
