 Initial Admiralty disruptive camouflage schemes employed polygons of varying shades of gray, blue and green so at least two of the colors would blend with background sea or sky under different light conditions. Schemes devised for capital ships emphasized identity confusion rather than concealment. HMS Queen Elizabeth became the first ship to receive an official camouflage scheme in January 1941. As more ships received similar schemes through 1941 it became evident the polygons were too small to be differentiated at effective camouflage ranges. Simplified Admiralty light and dark disruptive schemes were promulgated in 1942 to use larger and simpler polygons with no more than four colors. Light disruptive schemes were intended for use in the higher latitudes where skies were often overcast. Dark disruptive schemes used darker colors providing more effective disruption where bright sunlight could be expected.
