What is the chemical equation for the combustion of an ethanol-copper sulfate-water mixture?

For creating green flame, I know that you're supposed to expose a mixture or ethanol, copper sulfate and water into direct flame. My question is that if there is a chemical reaction for that, or is it simply CH3CH2OH + 3O2 --> 2CO2 + 3H2O (combustion of ethanol) with the copper sulfate not reacting (because I know the flame coloration is from the energy being released by the electrons of the copper).
