Popular Mechanics, maaliskuu 1914
That the war color of naval vessels was selected because of its invisibility by day rather than by night, is the statement recently made by a naval officer, and tests seem to show that a vessel painted in this color, while difficult to see in daylight, is easily picked up and made visible by a searchlight at night. in one case a vessel painted in the war color was detected at the distance of 17,000 yd. under the searchlight. There seems to be an insuperable difficulty in connection with this. For night work alone black is believed to be the best color, but this is a color too easily distinguished in daylight to be considered.
