Universal indicator is an aqueous solution of many indicators: methanol, propan-1-ol, phenolphthalein sodium salt, methyl red and monosodium salts of bromothymol blue and thymolblue. Most of these have a very complicated process associated with it during its manufacture.
Ascorbic acid and universal indicator together usually create a light green color.
Alkalis turn universal indicator blue or purple.
Green is the color that universal indicator turns to when it is neutral.
