Roland Piquepaille writes "In 'Things that show color in the night,' the Boston Globe reports that a company named Tenebraex is helping color blind people to travel. But it's also developing goggles to help soldiers and physicians to see all colors at night, and not only the green color of current night vision systems. These goggles, which should become available this summer, will be sold for about $6,000 to the Army. But as states one of the founders of the company, with monochrome night vision, 'blood is the same color as water.' So these expensive night vision devices might be more targeted to Army physicians than to regular soldiers."
