A unique and correct pH indicator for all the values of the pH scale don't exist; see the link below.
The colour of universal indicator is depending on pH pH Range and corresponding color: 0-3 red 3-6 orange yellow 7 green 8-11 blue 11-14 violet purple
When it is not mixed with any other solution, it is green. Green represents neutrality, so its pH is 7.
0-14, 7 is neutral, anything greater than 7 is a base, anything less than 7 is an acid
The pKa range of the compound is typically between 0 and 14.
The pH scale ranges from 0-14. Universal indicator makes very acidic substances (with a pH of around 0) appear dark red, neutral ones green and very alkaline ones dark blue.
The range of an instrument or any type of equipment are the ultimate limits for which it has been designed / constructed. A part of the measuring range is normally indicated as the span which complies with the calibrated standard output. The span is always smaller or equal to the range. For exampe a pressure transmitter range of 0 to 100 barg can be calibrated to measure a span of 20 - 80 barg and so the span is 60 barg. Note that the range still determines the accuracy !
Range is the highest minus smallest. The range would be 14.
The range of pH values is 0 - 14.

When it is not mixed with any other solution, it is green. Green represents neutrality, so its pH is 7.
The equator is located at 0 latitude. Fullstop. Being a parallel it spans the whole range in longitude, from 0 to 180 and back again.
0-14, 7 is neutral, anything greater than 7 is a base, anything less than 7 is an acid
Range = Maximum - minimum = 18 - 0 = 18
The pKa range of the compound is typically between 0 and 14.
Probabilities can only range from 0 to 1. All of the options range from 0 to 1 (14% is the same as 0.14) except -49, so -49 is not a probability.
The pH scale ranges from 0-14. Universal indicator makes very acidic substances (with a pH of around 0) appear dark red, neutral ones green and very alkaline ones dark blue.
The pH scale is between 0 and 14 but a pH under 0 is possible for some strong acids.
