I belive its red or my nose
Why does the colour of copper sulphate solution change when an iron nail is dipped in it? When an iron nail is placed in a copper sulphate solution, iron displaces copper from copper sulphate solution forming iron sulphate, which is green in colour. Therefore, the blue colour of copper sulphate solution fades and green colour appears.

Copper oxide will turn blue or purple when Universal Indicator is put on it.If you found this helpful, please rate me :)
Copper sulfate appears blue in color on the pH scale.
Copper Sulphate crystals before heating r blue....but after heating I dunno , may be u should try and ask your Sci.Miss/Sir I'll get back when I get the other answer .

Copper sulphate's colour is 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.
No colour
When a iron nail is dipped into copper sulphate solution after sometime the colour is changed into pale green.
When you dissolve copper oxide in water and add universal indicator, the solution will most likely turn blue or green. The exact color can vary depending on the pH level of the solution.
the copper sulphate i used at room temperature was blue.
very dark blue

The copper plates out while the zinc dissolves, leaving a transparent zinc sulphate solution.
