When something becomes bleached from the sun, where does the colour go?

The color doesn't *go* anywhere. The high energy ultraviolet radiation in sunlight simply destroys the molecules that give a particular object its color. Those molecules are colored because they interact with light, so they are naturally more susceptible to absorbing too much energy and having some or all of their molecular bonds broken.
