Sunshine consists of a complete array of photons of all colors and invisible ultraviolet and infrared rays all traveling at the "speed of light." Each photon is a tiny mass-less packet of energy that can be captured by the electrons orbiting about atoms and molecules. The photons can send electrons to higher more energetic orbits or even kick them out of their atoms causing ionization. The shortest wavelength photons like UV are the most energetic and penetrating (they can pass through an overcast sky and give you a sunburn when you thought you were safe!). Because the photons can affect atoms and molecules (breaking bonds) they can affect the complex chemistry of dyes and pigments. This can cause the colors to fade. Photo and photon have the same Greek root. right?

The UV (Ultra Violet) rays of the sun breakdown the pigments in the inks and paints.

any picture hung in direct sunlight will fade just like your curtains do.
it also fades wood .if you have a table in front of a window with an ornament on it and remove the ornament after a few weeks sunlight there will be a darker bit of wood in the middle of the table

UV rays hit your lens and changes the way the camera/camcorder sees everything and so changes the outcome.

Because it needs all the colour to shine in different places around the world.

To remind you of the awesome power of the sun. All life comes from it. Think about it. Perhaps God lives there.

the uv rays. Just like it changes the color of your skin when you tan or get a sunburn.
