Revised ANA Bulletin No. 157a, lists AAF, Navy, and British equivalent or superseded colors, and changes color 619 to “Bright Red” from “Insignia Red,” March, 1944

On March 24,1944, a revised ANA Bulletin No. 157a, Standard Aircraft Camouflage Colors, added atable showing the AAF and Bureau of Aeronautics colors equivalent to or superseded by these standard camouflage colors. The British nearest equivalent colors were also listed and were those for which the AN standard colors could be substituted. The name of color 619 was changed to read “Bright Red” in place of “Insignia Red”. A paragraph titled “Color Match” was also added and read as follows:

In order to determine color matches the subject standards shall be compared with the dry paint film under test by viewing un­der diffuse daylight illumination. The illumination shall be equivalent to International Commission on Illumination Illuminant “C” obtained from north sky light or suitably filtered artificial sources. The line of sight should be normal to the plane of the specimen and the standard. No water, oil or other means of moistening the surfaces shall be used. Color standards should be handled by the edges and suitable precautions taken to minimize drift due to exposure, soil, rubbing or other cause.

The added table read as follows:
