As you know that iodine act as indicator for testing of starch so when a drop of iodine is added to starch it turns bluish black but when added to distilled water nothing happens except the colour of water which turns brown and its is the colour of iodine.
When added to starch, the solution turns dark blue or black.
The colour of the iodine will turn from yellowish brown to dark blue
nothing happens but you can add iodine then it will change coulur

When you pore iodine on a piece of bread, the bread will turn black. Why? Because, the iodine has a chemical reaction with the starch in the bread. This method is great to find out if a food contains starch (I suggest a potato to try next!).
Iodine will color black-blue only with 'hydrated' swollen carbohydrate body within the soaked seed.
