Candide is the protagonist of the novel of the same name, by Voltaire. The name of the protagonist was chosen as a reference to the color white, in order to convey purity and innocence. Candide is honest, naïve and pure, and he seems to lack any type of corruption. Because of this, he can sometimes be susceptible to bad influences from others.
Some of the textual evidence that supports this position is the way in which Candide is able to change his beliefs in Pangloss's philosophy for the ideas that the old farmer teaches him. Another example is the way in which Candide is able to easily give his money to strangers.
