Have a look at this link, it lists alot of Acid/Base indicators including p-naphtholbenzein

Universal indicator covers a wider pH range compared to litmus indicator, which only detects acidic or basic conditions. Universal indicator provides a more precise indication of the pH level of a solution by producing a range of colors across the pH scale.
The pH range over which an indicator changes color is its transition range. This is the range of pH values over which the indicator molecule shifts between its acidic and basic forms, resulting in a visible color change.
The transition interval of an indicator refers to a range of values within which the indicator shifts from one state to another. It helps determine when a specific threshold or condition has been met, signaling a change in status or action. It is important to define transition intervals to effectively interpret and utilize the indicator for decision-making.
The selection of an indicator for a titration is based on the pH range over which the titration will occur. The indicator should have a color change that aligns with the pH at the equivalence point of the titration. Choosing an indicator with a pH range that encompasses the equivalence point will ensure accurate endpoint detection.
Acids typically change the color of an indicator by donating a hydrogen ion (H+) to the indicator molecule, altering its structure and causing a shift in color. The specific color change depends on the pH range of the indicator and its chemical properties.
The indicator that gives you the range of colors for different pH numbers is called universal indicator. It is a mixture of several indicators that changes color over a wide pH range.

Impossible to answer without more information and what you think "cocking indicator" means.
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.
PPI (plan position indicator).
Universal indicator is the best choice because it can indicate a broad range of pH values accurately, from acidic to alkaline solutions. This makes it suitable for a wide range of experiments involving pH variations. Additionally, universal indicator changes color based on the specific pH of the solution, allowing for easy and precise determination of the solution's acidity or alkalinity.
