A mixture that darkens in color due to a reaction is often one that involves the Maillard reaction, commonly observed in cooking. This reaction occurs between amino acids and reducing sugars when food is heated, resulting in the browning of meats, baked goods, and roasted coffee. Another example is the oxidation of metal ions in a solution, such as the darkening of iron salts when exposed to air.
