Detailed Solution

Due to Osmosis neither FeCl₃ nor K₄[Fe(CN)₆] move through semipermeable membrane

Because FeCl₃& K₄[Fe(CN)₆] are the solutes in a solution

Due to osmosis only water flows from low concentration region to high concentration region.

So no reaction occurs, so blue colouration is not observed
