Universal indicator..?

Question

many indicators have a single acid colour and a single base colour. why is it that a universal indicator shows a number of colours?

Answer 1

Because there are different levels of acidity… telling you if a substance is highly acidic… kinda acidic… neural… basic…very basic

Answer 2

each colour represents a different pH value. eg, green is neutral(pH 7). if it turns red, it shows that the substance is super acidic (aroundpH 2).
