But seriously, mold is usually white before it starts producing spores; the color of a mold (black, green, whatever) is the color of the spores. The location is probably where condensation— or a leak— drips onto the fabric to provide the moisture that mold requires in order to grow, which is why you see it below the cabinets but don't see it on the cabinets.
