Anti-flash white is a brilliant white color commonly seen on United States, British and Soviet nuclear bombers. The purpose of the color was to reflect some of the thermal radiation from a nuclear explosion, protecting the aircraft and its occupants.

Anti-flash white was used on the Royal Air Force V bombers force and the Royal Navy Blackburn Buccaneer when used in the nuclear strike role. British nuclear bombers were given – though not at first, until the problem was considered – pale pink and blue roundels and fin flash rather than the traditional dark red, white, and blue.
Anti-flash white was applied to several British prototype aircraft, including the British Aircraft Corporation TSR-2. Paint used on the British Avro Vulcan was manufactured by Cellon, and that on the Handley Page Victor by Titanine Ltd.
Many Strategic Air Command nuclear bombers carried anti-flash white without insignia on the under side of the fuselage with light silver-gray or natural metal (later light camouflage) on the upper surfaces.
The United States Navy A-5 Vigilante carried anti-flash white without insignia on the under side of the fuselage.
The Boeing E-6 in TACAMO role was painted anti-flash white but its roundels were not subdued.
Like the United States, some nuclear bombers had the under side of the fuselage painted anti-flash white with the upper surfaces painted light silver-gray. This was true for the specially fitted, single Soviet Tu-95V bomber that test-deployed the most powerful bomb of any kind — the 50+ MT-rating Tsar Bomba on October 30, 1961 — as it had the anti-flash white on all its undersurfaces and sides. The Tupolev Tu-160 of the 1980s was the first series-built Soviet/Russian bomber aircraft to be painted anti-flash white all over. leading to its Beliy Lebed "(White Swan)" Russian nickname.
Some variants of the Xian H-6 had the under side of the fuselage painted anti-flash white.
In addition to these military aircraft, Concorde was painted white to reduce the additional heating effect on the aluminium skin caused by the sun whilst the aircraft was flying at high altitudes, the skin temperature already being raised to over 90 °C (194 °F) at Mach 2 by aerodynamic heating.
