What is the reaction mechanism involved when Fehling's A is made to react with Fehlings B?

The blue solution is ascribed to copper (2+) in hydroxide, but what causes it to happen? I'd like some sources too. Thanks.

Answer:
Well, the blue color comes because of empty d orbitals in Cu2+. But, for correct explanation, learn about Crystal
Field Theory ( A transition metal concept ). Go to wikipedia and search for this theory.
