The color fastness to light of clothing is also called the color fastness to sunlight, which is to assess the degree of change in color of clothing under sunlight. Consumers sometimes find that after wearing some clothes a few times, the color on the reverse side is darker than the color on the front side. This is because the color fastness to light of this garment is too poor, and the front side fades after sun exposure.
