When exposed to the sun, fair skinned people tend to develop more melanin in their skin to help protect them form buring. This makes their skin darker (called a sun tan), however when exposure to the sun stops, the skin will lose the tan. Therefore the answer is No.

This is a photochemical reaction of decomposition: silver (black) is released.
When silver bromide is exposed to sunlight, it undergoes a photochemical reaction where it decomposes into silver metal and bromine gas. This reaction is used in traditional black and white photography to develop images on film. The silver metal forms the image on the film while the bromine gas is released into the air.
Stachybotrys chartarum, black mold's scientific name. It's a very toxic mold and it is almost everywhere. It can be lethal and if exposed to it contact a doctor. It is not healthy to inhale. To get rid of it, try bleaching it or even exposure to sunlight.
Black clothes absorb more sunlight and heat compared to white clothes which reflect sunlight. This absorption of heat by black clothes results in them feeling hotter when exposed to sunlight.
Black is quite a hot colour when exposed to the sun

Black absorbs sunlight. When sunlight hits a black surface, the color absorbs most of the light wavelengths, converting them into heat energy. This is why black objects tend to feel warmer when exposed to sunlight compared to lighter-colored objects, which reflect more sunlight.

The silver exposed to air combines with oxygen in the air to form silver oxide which is black.
Photodecomposition reaction occurs when silver bromide is exposed to sunlight. The sunlight causes the silver bromide to decompose into silver and bromine atoms, leading to a color change from white to grey or black.
White paper reflects more sunlight and heat compared to black paper, which absorbs more sunlight and heat. Therefore, black paper tends to get hotter faster and reach higher temperatures than white paper when exposed to sunlight.
Yes, black absorbs more heat than other colors because it absorbs a wider range of wavelengths of light, converting that energy into heat. This is why black objects can become hotter when exposed to sunlight compared to lighter-colored objects which reflect more light.
As the name suggests, photo chromatin is sensitive to UV/sunlight. Therefore, the chromatin which is sensitive to either UV or sunlight in general, would turn black in sunlight. As to why it turns black instead of other colours, it should be because of certain chemical processes that cause it to turn black.
