If it does not interact with chlorophyll, it will remain brown. If it interacts with chlorophyll, it turns blue-black.
The color in solutions depends on the solvent - the ethanolic solution is brown.

Why does glycogen change to red when iodine solution is added?
Iodine tests for complex sugars. Glycogen is a complex sugar and will change dark purple when iodine solution is added (color is irrelevant, all you really need to know is that the change to a specific color signifies a presence of a macro molecule)
What colour does iodine solution turn red litmus paper?
The color not change.
What could you say about a substance if it did not turn blue-black with iodine?
While presence of starch is indicated by the bluish-black color change of a substance with the introduction of Iodine, it doesn't necessarily mean the absence of starch is the substance doesn't become blue or black in color. If a substance doesn't become blue or black in color on the application of iodine, it means the substance doesn't form any complex with Iodine. Generally, when a substance creates a complex with Iodine, it is in blue color.
Will whole milk expect to react with a color change if mixed with iodine potassium iodide solution?
Any reaction; iodine is used to test the contamination with starch.
What are the chemical name of protein and iodine?
Iodine (I) is... iodine in English; and many proteins exist, each with a specific name.

Why does iodine change colour when starch is present?
The startch and iodine molecule interact- the electron energy levels are affected on the iodine enough to change the absorption spectrim and hence the color.

Why is it physical change when purple iodine appears when solid iodine is warmed?
Because the Iodine is undergoing a phase change, which is a physical change. The Iodine is going from a solid to a liquid (I presume), and it's changing color. Those are both examples of physical changes. Phase changes are easily reversible without the use of energy, you could just freeze the iodine, and have the solid again. As for the color change, that's true for a lot of elements, like Mercury. This is not an example of a chemical change because not only is it easily reversible, but because no new substance is formed. You still only have Iodine, but in a different phase, and in a different color.
