Well its not me that curious about things in life but its one of friend who asked me this question and I am still answerless. SO here it is.. "Why is it when it gets wet things get darker?? while water is colourless..!!???" Why wet things appear darker than their actual colour? :)

An object made up of several layers interact differently with the light and then the overall perception of colour will be dependent on the overall nature of light received by the eyes from the object. If you have some cotton fabric there are indeed two such layers, one of the loose surface fibers and the second one of the actual surface of cloth. The upper layer doesn't absorb significantly waves of any particular wavelengths, they only scatter the light falling on them. When this scattered light adds up to the reflected light from the opaque object, the result is the perception of a lighter tint. When the layer is removed, like if the cloth is soaked in water, the color is perceived to be darker. Most object have rough surfaces so we "see" the object by light from all directions that is reflected (diffuse reflection) in the direction of our eyes. When an objects is wet the water fills in the roughness so the light incident on it is reflected in only one direction like from a mirror or a piece of glass, so usually less light is reflected in the direction of our eyes so it looks darker. Objects that already have smooth shiny surfaces do not look darker when wet.

Ha ha ha Stella nice post and sure its after long time well ur observation is correct and the reason of it as far as i know is Reflection u know that we see color when its reflected from surface, some color they absorb and some they reflect. so when it get wets so reflection from that object is not as dry one so color look darker, though water has no color hope it solve the mystery for u and i am sure their would be others to give u information Take care

well the answer is quite simple , it is because of light reflecting off an object, water amplifies the color and if the object is dry it doesn't have the reflective quality of water, think how dazzling a body of water is when it is sunny and then cloudy, at is all about reflecting light
