One substance that fits this description is red cabbage indicator. In the presence of a base, the red cabbage indicator turns blue due to a change in pH.
If you blend red cabbage with water (the best ratio for this is 1:2, one cabbage leaf for two cups of water) and then add toothpaste the mixture will turn green. This indicates that toothpaste is a base. If you add vinegar instead the solution will turn red, indicating an acid.
The universal indicator is better than the red cabbage indicator because the universal indicator has a wider range of pH that it can explain why a substance is acidic or basic. The red cabbage indicator only tests the substance if it is an acid or a base. Also, the universal indicators are made carefully and it is manufactured in a precise manner so the results are very reliable. Red cabbage indicators will vary in concentration which could cause errors to occur in determining the pH of a substance.

Nothing, but red cabbage is a simple pH indicator at home (red in acidic solutions).
Lemonade will turn pink when red cabbage indicator is added to it. This color change is due to the red cabbage indicator being sensitive to pH levels. The acidity of the lemonade will cause the red cabbage indicator to change color to pink.
