The color range of the indicator would depend on which universal indicator you’re working with. Some universal indicators occur naturally (such as red cabbage juice) while others can be made of a combination of indicators with shorter active ranges.
When the indicator is in a stock bottle, its color will depend on the pH of the solution. Ideally, indicators are in a neutral solution, so its color should be very close to whatever color it would be in a neutral solution . universal indicator or its variants would be green, while red cabbage juice would be blue-violet).
