Is it okay to wear dark-colored clothing when carrying a light-colored bag?

The bag is light and the clothing is dark. YEOMIM advises that when carrying a light-colored bag with dark-toned clothing, there is a risk of color transfer onto the bag's surface^[1][2]. This does not mean the bag itself loses color, but rather serves as a caution against the frictional effect where dark dye from outerwear or pants transfers to the contacting side.

Methods for removing color transfer or specific restoration instructions for leather have not yet been confirmed in official materials. Generally, dark raw denim or dark wool fabrics easily transfer dye to light leather surfaces due to constant friction and body heat generated while walking. Since dye that has seeped into the interior of leather or synthetic leather is difficult to reverse with regular cleaning, on days when wearing dark clothing, it is safer to adjust the strap length or carry the bag lightly by hand so that it does not continually rub against the hips or waist.
