What is the difference between the litmus paper and universal indicator?

Litmus paper:
Litmus paper used to perform the litmus test which determines whether the sample/substance is acidic or basic. It is available in two types of strips, which are red and blue and works similarly as pH paper. The red litmus paper turns blue if the sample has an alkali, whereas in acids the blue litmus paper becomes red. In neutral, both litmus papers do not change their color if the sample is neutral.
Universal indicator:
A universal indicator is a mixture of dyes that begin with green color, but while added to a solution it changes color. The color that changes, not only specifies that the substance is acidic or basic, but it can show the position on the pH scale.
The key difference between the litmus paper and the universal indicator is that the universal indicators can change a range of various colors, so it is useful in determining the strength of an acid or base. Consequently, it provides accurate results as compared to the litmus paper, which only gives you an indication of whether the substance is an acid or alkali.
