What happens when water comes in contact with white copper sulphate crystals?

The white copper sulphate will become blue. This is because copper sulphate usually has 5 moles of H2O, but it has reached a temperature where all five moles will have detached themselves from the copper sulphate, so it will become anhydrous (without water) and white. Then, when water is added back to it, it returns to its original blue state.
