Presence of what??? Turn in what? it depends. The colors vary. Green is neutral. The more acidic a substance is the more red it becomes, but between the green and red are colors like pink, orange, yellow but red means most acidic. If its a base it starts to turn blue and the more alkaline it has begins to turn purple.
