Permanganate anion is usually oxidized to COLOURLESS $M {n}^{2 +}$

#### Explanation:

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

${\underbrace{M n {O}_{4}^{-}}}_{\text{deep purple}} + 8 {H}^{+} + 5 {e}^{-} \rightarrow M {n}^{2 +} + 4 {H}_{2} O$

VERY concentrated solutions of $M {n}^{2 +}$ are a pale rose.

You will have to supply a corresponding oxidation reaction.
