A "Color Reference" is a system or tool used to identify and communicate colors accurately. It often includes color swatches, codes, or charts that help designers, artists, and manufacturers select specific colors for their projects. Common color reference systems include the Pantone Matching System and RGB color model. These references are essential in various industries, such as graphic design, fashion, and interior design, where precise color matching is crucial. By using a standardized color reference, professionals can ensure consistency and quality in their work, making it easier to reproduce colors across different materials and mediums.
