ob - I think you'll find it's just the opposite…color increases life expectancy. (Note that furling foresails usually have a dark leach. The leach is the only part of the sail exposed when furled so exposure to sun when furled has less deleterious effect.)

Remember that white colored objects reflect NO light…and colored objects reflect light with the wavelength of the color observed. So the lighter the color of an object the more light (energy) is absorbed. It's the energy of the light's waves being absorbed (rather than reflected) that breaks down the fabric and robs it of its strength.
