scinerds:Rainbow Fragments on Spider Webs The entangled pearl necklaces pictured above are actually droplets of dew on a spider web. The subtle colors displayed here resulted when sunlight illuminated the web, creating a multitude of rainbow fragments. Note that, in general, the smaller dew drops, residing on the thinnest silk strands, are nearly colorless. With these smaller drop sizes, wave interference acts to diminish coloration because colors tend to overlap one another. -- source link
