A dark tone scheme in color matching refers to a design approach that utilizes darker shades and tones to create a visually cohesive and sophisticated look. This scheme often includes a palette of deep, rich colors like dark blues, greens, purples, and browns. Dark tones can create a sense of depth, elegance, and mystery in design, making them popular in fashion, interior design, and other creative fields. When implementing a dark tone scheme, it is important to balance the colors and add highlights or contrasts to prevent the design from feeling heavy or overwhelming.
