it changes its color coz its no longer hydrated ie loses its water therefore color changes and also due to the change in oxidation state of cu there is a color change.
to get back the color leave it in an open environment (on a table) and as the copper sulphate absorbs the moisture it will get back its blue color

a) when it is heated up, it becomes dehydrated as it loses the water.
b) to restore color, add water back
