The method that uses the color changes of several indicators to measure the pH of a solution is called the Universal Indicator method.

Here are the steps:

1. A universal indicator is a blend of pH indicator solutions designed to identify the pH of a solution over a wide range of values. The universal indicator changes colors according to the pH of the solution.

2. The universal indicator is added to the solution whose pH needs to be measured.

3. The color change is then observed and compared to a standard color chart. This chart provides a color-to-pH correspondence.

4. The pH of the solution is determined based on the color it turns when the universal indicator is added.

This method is commonly used in laboratories to roughly gauge the pH of a given solution.
