Litmus is not affected by pure water because it is a neutral substance. Additionally, substances that are not acidic or basic, such as sugar or salt, will also typically have no effect on litmus paper.
Litmus paper is typically blue. If water is tested with blue litmus paper and it turns red, it indicates that the water is acidic. However, if there is no color change, the water is neutral.
The blue litmus paper turns red in acidic solutions, and the pink litmus paper turns blue in basic solutions. This color change is due to a change in the pH of the water affecting the chemical structure of the litmus dye on the paper.

Litmus paper is a sort of dark mauve colour in neutral substances like water. It was traditionally described as 'claret', though I never thought it looked like the claret I drank.
It depends whether the water is pure (Green) or with alkalis in it (Blue)
There are different types of Litmus paper and so the exact color may differ for each of these types. Also, water itself is neutral when pure but most tap water is slightly basic so it depends on what you use. -- Tap water will not cause any colour change when tested with litmus paper. Blue litmus paper remains blue, the same goes for red litmus paper. Although the above statement says that tap water is slightly basic, the pH is still close to neutral and will not be significant enough to cause a colour change for the litmus paper.

There are different types of Litmus paper and so the exact color may differ for each of these types. Also, water itself is neutral when pure but most tap water is slightly basic so it depends on what you use. Some types of Litmus paper will not change color in pure water (such as the 1-12 pH yellow litmus paper), others will turn a purple color as an indication of the solution being not an acid (red) or a base (blue).

Red litmus paper remains red when dipped in water. Litmus paper is used to test for acidity or basicity, and red litmus paper turns blue in basic solutions. If the water being tested is neither acidic nor basic, the red litmus paper will not change color.
An acid turns blue litmus paper red. This is because the acid donates a proton (H+) to the water in the litmus paper, changing the pH and causing the litmus paper to change color.
