Yes.. That's rgt because in month of July there will be hot climate which make copper sulphate to lose its water molecules and its color will fade.. Hope this will helpful

No. Anhydrous copper sulphate does not have water of crystallisation and it is greyish white in colour. It turns blue when has water of crystallisation.
So the water vapour present in atmosphere react with the anhydrous salt and it will gain blue colour
