Aircraft warning paint is a system of red/orange and white paint scheme that allows for aircraft to avoid colliding with tall objects like radio masts and other tall objects (during daylight hours) that may pose a collision threat to aircraft.
Aircraft warning paint serves the purpose of identifying tall structures in daylight conditions, they are often utilized in urban areas where lighting is drowned out or communities where the classic white strobe lights that normally are used during the day are considered a nuisance.
Most structures that have warning paint are painted aviation red/orange and white stripes.
Multiple patterns can be used for aircraft warning paint, including stripes, checkerboards, spheres, and teardrops.
Alternatives include aircraft warning lights and flag markers.
