dark green
If it is pure water, it doesn't change.
The water solution of iodine turn blue litmus paper to red.
Litmus paper is a commonly used pH indicator. Litmus is a water-soluable mixture of dyes extracted from lichens. When the paper is dipped into an acidic solution, the paper absorbs a proton from the acidic solution, and it creates a new compound inside the paper that absorbs lower energy light (red light). This makes the paper appear red.
A bleaching agent turns litmus paper white. For example, chlorine gas turns damp blue litmus paper red, and then bleaches, making it white.
The litmus paper changes to green because water has a neutral pH (7) andgreen is the neutral color.
If it is pure water, it doesn't change.
It would turn Green
as rain water is slightly acidic so will turn the blue litmus paper a little red.
Nothing particularly happens.

Some substances do not change the color of litmus paper because they are neither acid or nor base. They are called neutral substances.
The water solution of iodine turn blue litmus paper to red.
THE COLOUR of the litmus paper will not change as a salt solution is neutral
