UV or ultraviolet sensitive paint is paint that responds to long-wave radiation ultraviolet waves also known as black light. There are two major ultraviolet paints. One kind shows clear or white under white light and when placed under a black light will glow a different colour dependent on the colour in which it was originally painted with. The second type shows bright under white light and appears to glow when under black light.

Hunters can utilise UV paint to paint duck and goose decoys. It is thought that the feathers of certain fowl reflect UV rays and that birds can also see some ultraviolet light rays that humans cannot. This is one of the reasons blinds are used for hunters. Thus, using UV paint on decoys adds a sense of realism and may also increase the likelihood that birds will be attracted to the decoys.
Although discouraged by the FDA, many individuals utilise UV paint for face painting. According to the FDA, many of the pigments used in UV paint are suitable for screen printing and industrial uses and not safe to be applied to skin. Because UV ink cures with exposure to ultraviolet light and does not evaporate, blistering, irritation, redness and rashes may occur on the skin when applied. Also, if sensitivity occurs, less UV paint in a following application may cause irritations.
Utilising UV paint on a vehicle requires some preparation and attention to certain details. The auto should be a light colour, or the area that UV light is being applied to be a light colour to allow greater reflection of the UV light rays. Painting should be completed under a black light, to allow less error in the painting process. Apply three or more coats of the UV paint to allow greater durability and longer UV effects. Apply an Epoxy clear coat over the UV paint when complete to help protect the area.
An FDA approved UV ink used to mark and track fish and animals is also used in tattoo ink. Although not approved for humans, the ink, called Chameleon black light ink has been used for about 10 years for human tattoos. According to the FDA, some ink particles may be rejected by the body and form bumps in the tattoo site. A rare complication may be a burning sensation or swelling when receiving an MRI (Magnetic Resonance Imaging). Also, some individuals may be allergic to the UV pigments and experience skin irritation not associated with typical tattoo inks.
