Water is NOT Universal Indicator. Water is often referred to as a Universal Solvent as a large number of substances are soluble in it.
Universal Indicator is a chemical agent that can be used to test the pH of a liquid.
A pH indicator is used only to measure the pH of the solution.
since water is pretty neutral, the water does not change color but the universal indicator does. The universal indicator changes color as per the quantity of deionized water... But it changes to straw color or pale yellow in 50mL of deionized water.
Salt water typically forms a neutral pH solution, so it will likely appear green in universal indicator.
It will become orange because CO2 is an acid
A watercolour with a universal indicator is a solution that includes a pH indicator that changes color depending on the acidity or alkalinity of the water. Universal indicators typically range from red in acidic conditions (pH < 7) to green at neutral (pH 7) and blue/purple in alkaline conditions (pH > 7). When mixed with water, this indicator provides a visual representation of the water's pH level, allowing users to assess its chemical properties easily. It is often used in educational settings to demonstrate pH testing and the effects of different substances on water quality.

Water typically turns green in universal indicator. This indicates that water is neutral, neither acidic nor basic.
Universal indicator is a mixture of dyes that changes color in response to different pH levels. It is used to determine the approximate pH of a solution by observing the color change of the indicator when added to the solution.
When universal indicator is put in water soluion of alkalis (base) it indicates significant blue colour.
When water is mixed with a universal indicator, it will change color based on the pH of the water. Universal indicator contains a mixture of dyes that change color in response to different pH levels, allowing you to determine if the water is acidic, neutral, or basic.
Salt water typically forms a neutral pH solution, so it will likely appear green in universal indicator.

The universal Indicator was invented in 1923 by Yamada
When universal indicator is added to water, it will change color based on the pH of the water. Universal indicator shows a range of colors corresponding to different pH levels, such as red for acidic solutions, green for neutral solutions, and blue/purple for basic solutions. This color change allows you to determine the approximate pH of the water.
Use of paper avoid the contamination of the sample.
The gas that turns a universal indicator blue is usually chlorine.
