Why does a drop of food colouring in a container of water start as a drop but eventually colour the entire water?

The droplet spreads out as it dissolves in the water. It occupies the same space as the water, turning it colours the water a lighter shade of the colour of the original droplet. This due to the droplet being diluted by the water when it is mixed into the water.
