Sorry but I don't know

What color do alkalis turn universal indicator?
When universal indicator is put in water soluion of alkalis (base) it indicates significant blue colour.
If you add alkali to water what colour would the water be?
Alkalis are bases dissolved in water. They do not have specific colours and are often colourless liquids.Indicators are used to determine the strength of an acid or alkali and change colour when exposed to the liquid.Look at Universal Indicator Solution.

indicators change colour because of your pee.
What is the difference between hypothesis and prediction?
Hypothesis is the aim of the experiment. It could be to see if there is a colour change when mixing two chemicals together. Prediction is just a guess, which could be based on evidence, data or just a wild guess. You could predict that there would be no change in colour when the two chemicals are mixed together.
What colour is litmus paper when it is alkalis?
