Distemper is a decorative paint and a historical medium for painting pictures, and contrasted with tempera. The binder may be glues of vegetable or animal origin (excluding egg). Soft distemper is not abrasion resistant and may include binders such as chalk, ground pigments, and animal glue. Hard distemper is stronger and wear-resistant and can include casein or linseed oil as binders.
Distemper was used extensively by German and Soviet forces for winter camouflage during World War II. Because ordinary camouflage patterns were ineffective in the heavy snow conditions on the Eastern front, aircraft, tanks, and other military vehicles were hastily brush-painted with plain white distemper during the winter of 1941–1942. Because distemper is water-soluble, photographs showing winter camouflage often show it badly eroded
