Chlor/o denotes green. It comes from Greek chloros meaning greenish-yellow or pale green. This root appears in chlorophyll, the green pigment in plants, which is why the color associated with chlor/o is green. You’ll also see it in terms like chlorosis, referring to a greenish-yellow pallor. Other color roots you might encounter include cyan/o for blue, erythr/o for red, and leuk/o for white, which helps differentiate them from chlor/o.
