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
Hydrated                         Anhydrous 
Copper sulphate               Copper sulphate

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