Actually, Mn(2+) solutions are also pink, but because of a doubly forbidden electron transition (explained in coordination compound chemistry and simmetry rules) this color is particulary faint.This final reduction product is obtained in acidic enviroment. I personally recommend KMnO4 in nitric acid, and then add oxalic acid as the reducing agent.Greetings from Colombia (not Columbia, USA <_<)

You are absolutely right! Thank you for noticing :)

Your title is misleading. It is some of the oxidation state of manganese that you are looking at. You should reduce it further to manganese(II) which looks colourless in aqueous solution but is pink as a solid salt.
