A process for coloring treated and untreated green olives by using chlorophyll, chlorophyllin, and copper chlorophyllin salts is presented. The process includes soaking salt out of the green olives in sodium chloride of density from about 0% to about 7%. The process also includes sinking the green olives into a first fluid solution holding sodium hydroxide and other metal hydroxyl groups from about 0% to about 3.5%, chlorophyll chlorophyllin salts and copper chlorophyllin salts, in a ratio of olive liquid from about 0.45 to about 4. The process then includes leaving the green olives in the first fluid solution from about 1 hours to about 72 hours, removing the green olives from the first fluid solution, washing the green olives with water, and sinking the green olives into a second fluid solution holding an acid until a PH of the green olives becomes less than about 4.6.
