This requires a knowledge of crystal field theory. The d electrons that surround copper can be excited by light. This absorption of red/yellow causes the colour to appear blue.
Blue...but you could just google this in google images...??
Hydrous copper sulphate, when heated, turns into anhydrous copper sulphate and changes its color from blue to white. The blue color comes from the water molecules bound to the copper sulphate crystals, and when heated, these water molecules are removed, resulting in a color change.
Water changes blue anhydrous copper sulphate crystals to white by creating hydrated copper sulphate, which is white in color.
Ferrous Sulphate, also known as Iron (II) sulphate or green vitrol is green.
the copper sulphate i used at room temperature was blue.

Copper sulphate's colour is blue.

Sulfate/Sulphate dissolved in water is blue in color. That's COPPER sulphate; there are many other sulphates which have many different colours, or are colourless.
When blue copper sulphate is heated, it loses water molecules and converts to anhydrous copper sulfate, which is white in color. The blue color of copper sulfate is due to the presence of water molecules in its crystal structure.
When copper sulfate is added to sodium hydroxide, a blue precipitate of copper hydroxide is formed. The color change observed is from the initial blue color of copper sulfate to the blue precipitate of copper hydroxide.
Blue vitriol is a very obsolete name for the copper(II)sulphate: CuSO4. Don't use in the future this term. Pentahydratated copper(II) sulphate: CuSO4.5H2O - bright blue color After the dehydratation of the above compound we obtain the anhydrous copper(II) sulphate: CuSO4 - pale green color.
