Answer:

Depends. Smoke dampers actuate based on an alarm condition from a duct smoke detector, Fire dampers work from heat from a fire.
This is obviously not water absorption, since water absorbs red (and thus appears blue), while slightly damp clothes do not become ocean blue. Note that this darkening is true for many surfaces - rough stone, sand on a beach, wood, paper, etc. What happens is that all these materials are either porous or are made of small particles which have a lot of surface area. The light is refracted and reflected by those surfaces and bounces back at the viewer almost immediately, making the material appear white (or brightly colored). If the light wasn't bouncing back, and traveled further into the material, more of it would get absorbed by impurities etc, and the material would look darker. One way to eliminate reflections/refractions on the surfaces of the particles is to surround them with a liquid that has similar refraction index, and water happens to be much closer, compared to air, to both glass (of which sand is made) and plastics and proteins, of which clothing is made. So, in wet materials, light travels farther in. Sometimes the liquid can help it travel right through look at oiled paper!
