Answer:

Because Cu is less active metal than zinc.

Copper is less reactive than zinc. So it cannot displace zinc ion from zinc sulphate solution. Hence there is no reaction. But, as zinc is more reactive than copper , so it displaces copper ion from copper sulphate to form zinc sulphate, which is not blue in colour.
