Color classes are expressed in millimeters (mm) Pfund as compared to an analytical grade glycerol standard reference. The natural color of untreated honey comes in many tones and it originates from the botanical varieties used by the bees. However, color tends to darken with age or change according to the method of conservation or production used by beekeepers. These practices can include the use of old beehives, contact with metals, the temperature of conservation, and exposure to light.
