Corrosion of Nails Experiment

I am a tertiary student in Singapore and have a question about corrosion of nails in ferroxyl indicating solution (the contents are NaCl, potassium_ferricyanide [affil links] and phenolphthalein ⇦ this on eBay & Amazon [affil links] ). After the experiment, I found colour of greenish-blue and pink-red on the nails in the solution. What could have caused this situation? please advise... Thank you...

That partly depends on what type of nail you were using, bright finish, electroplated, galvanized, bronze, brass, or something else? The end product depends on the sum of the reactants.
