3.2.2.1 Visual Shade matching. The color and appearance of the undershirt shall match the standard sample when viewed using the AATCC EP 9, Option C, (see 7.7) with a primary light source simulating the spectral quality of average daylight, CIE Illuminant D65, with a color temperature of 6500 (± 200) Kelvin (K) illumination of 100 (± 20) foot candles. Alternatively, the color and appearance of the undershirt shall match the standard sample with a primary light source simulating artificial daylight, CIE Illuminant D75, with a color temperature of 7500K (± 200) illumination of 100 (± 20) foot candles in lieu of D65. (See 7.7.1). The undershirt shall also be a good match to the standard sample with a secondary source simulating the spectral quality of incandescent lamplight, CIE Illuminant A, with a color temperature of 2856K (± 200). The light source used shall be indicated on the test report and the DD Form 1222 if Government shade evaluation is requested.

NOTE: In case of confusion, the viewing geometry should be “The specimen plane and illumination source will be parallel to each other and aligned so that the light flux is incident at the center of the specimen plane, which is set at a 35 (± 5º) angle relative to the horizontal. The observer will view the specimens at a 90o angle, relative to the plane of the specimens”.

7.7.1 In 2022, the U.S. Military (all Services) accepted D65 as the new preferred light source for visual shade matching due to the supply chain issues with D75.
