Retro color matching in design refers to the use of color schemes inspired by past eras, often characterized by vibrant, bold, or muted tones reminiscent of a specific historical period. This approach is popular in fashion, interiors, and graphic design, where it can evoke nostalgia or create a distinct aesthetic that stands out. Retro color matching involves selecting colors that were popular during a particular era, such as the 1950s, 1970s, or Art Deco, and incorporating them into a cohesive design scheme.
