An engineering method has been developed for minimizing the contrast of a Navy vessel under specified conditions. The purpose of this report is to describe the method and to illustrate the effectiveness of its use. The visual target selected to demonstrate the method was a destroyer. To facilitate the calculations, the form of the destroyer was simplified. A three dimensional model was employed approximating but reducing in complexity the general structure of the ship by retaining the actual side, top and front PROJECTEDAREAS. Although the sighting ranges of an aerial observer were minimized by the concealment paints, the sighting ranges of an observer at sea level are greater than for the same ship painted with standard Navy paint. The appearance of the two ships when viewed against the horizon sky from the front and from the rear. In the first case the lighter paint on the standard vessel has made it lighter than the background whereas the concealment paint makes it appear as a dark target. From the rear both are seen in the shadow and are dark targets, with the standard vessel slightly less visible.
