(apart from white or black of course)
(is this a suitable topic for dis?)
so the fabrics will shine if they reflect a strong light-source into your eyes, but won't reflect ambient light as diffusely and therefore strongly as dry fabrics
less light = darker
The explanation is that many of the things we think of as white look that color because they are made up of small particles which are transparent (like the sand on the beach which is essentially glass) but which scatter light effectively because they are small and rough with a lot of surface area. Because the particles scatter all the wavelengths of light right back at the viewer, the material appears white. If the material didn't scatter the light so strongly, the light could penetrate the material to a deeper level and would travel a longer distance inside the material before it gets back out to the viewer's eye. Along this distance the light can be absorbed by small impurities decreasing its intensity and the material would then appear to be darker. One effective way that one can decrease the amount of scattered light is to get rid or reflections at the surface of the individual particles. This can be done by surrounding the particle entirely by an index matching fluid. (That is by surrounding it with a liquid that has the same index of refraction as the object itself.) Water helps get rid of scattering in just this way. Although it does not have the identical index of refraction as that of the particles, its index is still much closer to it than that of air. Thus when the object is wet, the light does not get reflected or scattered as efficiently at each interface and the light penetrates farther into the object. The wet material then appears to be darker than the dry one.
I hear that brother.
that things start to get trickier
Bet he's invented some special pants. The cunt.
that you can get to cook non toasty things in a toaster?
(well not quite like that, but using similar devious thinking)
