Permanganate anion is usually oxidized to COLOURLESS #Mn^(2+)#

Explanation:

And we would represent this reaction by the 5 electron reduction.....

#underbrace(MnO_4^(-))_"deep purple" + 8H^+ + 5e^(-) rarr Mn^(2+) + 4H_2O#

VERY concentrated solutions of #Mn^(2+)# are a pale rose.

You will have to supply a corresponding oxidation reaction.
