The purple color of the KMnO4 will change to a muddy brown.
potassium permanganate will go from pink to dark blue indicating that it has been reduced
When ethanol reacts with potassium permanganate, ethanol forms ethanoic acid. Potassiun permanganate turns into manganese(ii) ions. So the purple colour of permanganate dissapear.
purple
no reaction

When potassium permagnate is added initially to ethanol, ethanol gets oxidised into ethanoic acid using potassium permagnate. Thus, decolorizing potassium permagnate. When excess is added , the color of potassium permagnate persists.
When potassium permanganate reacts with ethanol, it releases oxygen. ie, an atom of oxygen thus converting the ethanol to acetic acid. Initially colour disappears because coloured permanganate ions of potassium permanganate are consumed to oxidise ethanol. C 2 H 5 OH (WITH ALKALINE KMnO 4) CH 3 COOH+H 2 O Remember :When excess is added colour does not change because there is no more alcohol left and hence there is no reaction.

In this i think change of colour takes place
The colour of aqueous potassium permanganate ranges from violet to lighter shades of purple depending on its concentration.Please see the related link below to see an image bench scale testing of potassium permaganate showing the range of colour that it can appear.
The dark brown color is due to the formation of manganese dioxide (MnO2)

Purple colour
as it is pink in colour so no external agent is required for titration when we titrate againist another component it will changes it colour to pale pink asd it is end point

Bromine is solution is orange/red depending on how dilute it is. Potassium permanganate solutions are purple.
A water solution of potassium permanganate is formed.
The dark purple color of permanganate fades because during the reaction permanganate is reduced to manganese cations and water. The other reactants and products are not strongly colored.
according to the amount we put the change from dark purple to pink color
