Hydrated Copper Sulphate crystals [CuSO4.5H2O] are blue in colour.
When copper sulphate crystals are heated strongly, they loose all the water of crystallization and form anhydrous copper sulphate [which is white in colour].
CuSO4.5H2O ---------> CuSO4 + 5H2O

The water of crystallisation gives the crystals of their salts their shape and colour.
