A red cabbage indicator is a liquid made from mashed up red cabbage which you then put in a liquid to see whether it is acidic or not.
If it is acidic the liquid would turn reddy orange and if it was an alkali ( the opposite to acid) it would turn purpley blue.
This is if the liquid was clear in the first place.

Why is the universal indicator more useful than the red cabbage?
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.
