NIVO, abbreviated from Night Invisible Varnish Orfordness (or "Night Varnish Orfordness"), was a dark grey-green overall finish applied to British night bomber aircraft in the inter-war period (1918-1939).
By the mid 1930s, tests had determined that the varnish was too reflective when searchlights were shone on it. NIVO was phased out in the late 1930s, and had been discontinued by the time of the arrival of the new British medium bombers - the Vickers Wellington, Handley Page Hampden and Armstrong Whitworth Whitley.
