Washing Dark Clothing
Dark color introduces concerns about fading and dye transfer, but it does not eliminate differences in fabric and construction. A heavy dark garment and a delicate dark blouse may need separate loads. Check care labels, handle uncertain dyes cautiously, and choose compatible temperatures and products instead of treating every black or navy item as interchangeable.
Separate colors and test uncertainty
Ariel advises keeping dark garments apart from whites and checking uncertain dyes before mixing items. Turning dark clothing inside out can protect the visible surface during washing. The guide connects sorting with the risk of color transfer rather than assuming that every dark garment is reliably colorfast.

Use a compatible cycle and temperature
Cooler washing can help limit fading, but the care label remains the reference for the finished item. Select detergent and cycle settings suited to the load instead of relying on color alone. A dark delicate fabric and a heavy dark garment may need different treatment even though both belong outside a white load.
