Twelve P-36C's were painted in this unusual camouflage, in the picture accompanied by six "normal" painted aircraft. The schemes were of three classes:
Class I: One to three dark colors on top (ground camouflage) with white or gray underneath (sky camouflage).
Class II: The ground camouflage on top with the outline broken up by sand or white. No camouflage underneath.
Classs III: Confusion scheme, non-concealment with the same camouflage colors being used on top and underneath.
Within each Class there were several variations on patterns and colors. The colors used were water based temporary camouflage paint, as follows: Dark Blue, Dark Green, Dark Olive, Neutral Gray, Sand (believed to have been an orange shade of sand), Sea Green, and White."
