Dark heather describes a blended color, typically in textiles. It is characterized by a mix of dyed and undyed fibers, usually cotton or a cotton blend, creating a salt-and-pepper or mottled effect. This results in a muted, sophisticated tone, falling within the gray spectrum, often with subtle undertones of other colors depending on the dyes used. As an example, a dark heather gray t-shirt will appear as a dark gray with a slight textured visual, lacking the solid, flat appearance of a uniformly dyed fabric.
The appeal of blended fabrics stems from their visual depth and often improved durability. The variation in fiber color obscures minor imperfections and wear, contributing to a longer-lasting, aesthetically pleasing garment. Historically, heathered fabrics gained popularity as a cost-effective way to utilize imperfectly dyed materials and have since become a staple in casual wear and athletic apparel due to their comfortable feel and stylish appearance.
