When the things are wet, the water fills in some of the spaces between the fibers. This water acts just like a fiber optic cable, carrying the light through the material instead of reflecting it back to your eye. Since more of the light goes through the material, less of the light is reflected back and the wet spot looks darker.
When objects are wet, they appear darker because the water on their surface absorbs and scatters more light, reducing the amount of light reflected back to our eyes. This makes the wet objects appear darker compared to when they are dry.
When surfaces get wet, the water fills in the microscopic crevices and spaces, causing light to scatter and be absorbed rather than reflected. This makes the surface appear darker because less light is being reflected back to our eyes.

I am many colors but live briefly. While I exist things usually get wet. What am I?Answer : Rainbow ( by Hogarth on Dun server ! )
Sand, dirt, and other dry things weigh more if it is wet.
light refraction
When sandstone gets wet it absorbs the water and its colour gets darker.

When objects get wet, the water fills in the spaces between the materials, which changes how light interacts with the surface. This change in light refraction and reflection can make the object appear darker because the water on the surface absorbs more light. Additionally, water can enhance the contrast of colors on the surface, making them appear darker or more saturated.
Tarmac appears darker when wet because the water fills the pores in the surface, reducing the reflection of light. The water on the surface creates a smooth layer that decreases light scattering, making the pavement appear darker.

All surfaces eventually acquire scratches which tend to scatter light instead of reflecting it evenly. This makes things look dull and whiter. Wetting things tends to nullify the effect of scratches, which makes things look glossier and darker.
It absorbs some water, so looks darker.
things that are not wet
Because wet hair repels light and weighs down your hair... Once the water evaporates the colour of your hair gets lighter because it reflects light. When its wet light takes a longer time to penetrate through your hair, thus leading in a darker colour... Until it drys. Your Welcome, x
Something that is damp or emptiness. These two things are not wet or dry.
