How is the brick-red coloration formed by Benedict's reagent in the prescence of reducing sugars?

How is the brick-red coloration formed by Benedict's reagent in the prescence of reducing sugars?
One of the components of Benedict's reagent is copper(II) oxide.when it is placed in solution with a reducing sugar, the copper(II) oxide is reduced to copper(I) oxide ions. this has a brick red colour. if there a small or large amount of the reducing sugar present, the color would range from green to brick red respectively.
