This might not be your answer, but universal indicators change colour when they come in contact with a substance. It will then change to the colour of its corresponding pH. So, in terms of bases, it turns from a turquoise (from green which is pH7) to a dark purple the more alkaline it is(<7-14) and in terms of acids, it goes from a green-yellow to a dark red (>7-0).
