Chlorophyll is a green pigment found in most plants, algae, and cyanobacteria. Its name is derived from the Greek ?????? (chloros "green") and f????? (phyllon "leaf"). Chlorophyll absorbs light most strongly in the blue and red but poorly in the green portions of the electromagnetic spectrum, hence the green colour of chlorophyll-containing tissues such as plant leaves. Chefs use chlorophyll to colour a variety of foods and beverages green, such as pasta and absinthe. Chlorophyll is not soluble in water and is first mixed with a small quantity of oil to obtain the desired result.
