> When I was in the military, a key tactic of camouflage was to never, under any circumstances, expose yourself on a hilltop or similar, where your silhouette could be easily identified. A dark blob on a light background is far easier for the human eye to see, than the reverse. There's a scenarion when this is incorrect: when the light foreground is the only source of light. I use black backgrounds with white text for reading on OLED because the only light entering my eyes is the information I need. You can tell me all you want that it doesn't reduce eye strain, it does. I can tell because I can feel my eyes.
