Blue!! Because pool water is alkaline and alkalis turn red litmus paper into blue.
THE COLOUR of the litmus paper will not change as a salt solution is neutral
Litmus paper does not show green colour, only red and blue in acidic and alkaline media respectively. In fact, litmus paper does not change its colour in neutral solutions.
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.
It's purple the colour can change slightly. isn't that just great purple it's my favourite colour ya know
In acid solution, blue colour of litmus is changed into red. In basic sol litmus change to blue.
baking powder will not show any colour change in litmus soltion because water is absent but wen it is mixed wid water and then subjected to the litmus solution, the red litmus wud change to blue.
The colour remain unchanged.

Blue litmus paper
The paper changes colour from red to blue. This is because when you mix MgO with water, you now have Mg(OH)2 solution which is basic and hence changes the colour of red litmus paper to blue.
Yes, sea water would change color with red litmus paper because sea water is basic. Under basic, or alkaline, conditions, red litmus paper turns blue. Being between the pH range of 7.5 and 8.4 (between 7 and 14 marks basic conditions), sea water is basic and, therefore, the red litmus paper will change color.
Some substances do not change the color of litmus paper because they are neither acid or nor base. They are called neutral substances.
