Sometimes beauty isn’t a color—it’s the way light chooses to travel.
Field Notes
Spider silk is almost invisible until sunlight strikes it from just the right angle. As light bends and diffracts around strands only a few micrometers wide, different wavelengths separate, producing thousands of tiny flashes of color. The silk itself isn’t colorful—the rainbow exists only in the path the light takes. For a few fleeting moments each morning, an ordinary web becomes one of nature’s most spectacular optical displays before quietly disappearing again.
