Answer 2

Reds, blues and purples occur because of a concentration of different kinds of anthocyanins, water-soluble pigments held in plant cell sap. Heating doesn't change them, but they are red in acidic conditions and blue or purple in alkaline conditions. The color of fall leaves happens when the leaf chlorophyll dies.
