it is bright pink!

Hydrated Copper Sulphate is CuSO4.5H2O and Anhydrous copper sulphate is just CuSO4. Therefore, hydrated copper sulphate has extra mass due to water molecules present in it.
Anhydrous or hydrated copper sulphate crystals? And from what?
CuSO4
The hydrated copper sulfate (blue color) become white after heating and releasing of water; the white anhydrous copper sulfate is obtained.
the copper sulphate i used at room temperature was blue.

copper sulphate gets hydrated in water and thus is diffusible.

CuSO4
The hydrated copper sulfate (blue color) become white after heating and releasing of water; the white anhydrous copper sulfate is obtained.
On heating hydrated Copper Sulphate (CuSO4 . 5 H2O), the result is the removal of water molecules of crystallization, which for this very compound is 5 molecules per molecule of copper sulphate. The process cited above is termed as dehydration.
On heating penta hydrated copper sulphate undergoes dehydration and changes colour from blue to white that means physical change but on heating it does not show a chemical change.
Copper sulphate's colour is blue.
the copper sulphate i used at room temperature was blue.
The colour of Copper sulphate is blue because Copper ions absorb light in all frequencies except blue which is reflected instead.
Blue
The anhydrous copper(II) sulfate is white, the pentahydrate is blue.Iron is gray.
