the chlorine in the water oxidizes the copper causing an off color, if you used enough of each it would turn a greenish blue color.

What is the change in color in testing for the presence of protein in egg albumin using solution sodium hydroxide and copper sulfate?
Copper sulphate when mixed with a protein will turn purple if the amount of protein is sufficient enough in quantity to trigger the reaction. Planex1234 says; No offense but i think it is starch that turns dark blue - purple. Thetada says: the colour changes are arguably similar. Iodine solution goes blue/black in the presence of starch. The colour that sodium hydroxide / copper sulphate solution goes in the presence of protein is variously described as mauve / purple.

What is the colour change when sodium hydroxide is added to iron II sulphate?

What happens when EDTA is added to a solution of ammonia and copper sulphate?
The water soluble copper sulfate produces Cu(II) ions in solution. The soluble ammonium hydroxide produces ammonium ions and hydroxide ions in solution in equilibrium with ammonia and water. NH4OH(aq) ↔ NH3(aq) + H2O(l) The ammonia molecules react with the cooper ion to produce a complex ion of Cu(II) coordinated with four ammonia molecules. Cu2+(aq) + 4 NH3(aq) → [Cu(NH3)4]2+(aq) That complex ion in turn associates with a water molecule and the sulfate ion resulting in the products of the overall reaction. CuSO4(aq) + 4 NH4OH(aq) → Cu(NH3)4SO4H2O(s) + 3 H2O(l)
