Twelve advanced colors refer to a specific palette or set of hues that are considered particularly sophisticated or complex in color theory. These colors might include deep, rich shades, vibrant tones, or subtle hues that are often used in art, design, and fashion to create a sense of depth and sophistication. In color theory, advanced colors can be part of a color wheel that includes primary, secondary, and tertiary colors, as well as shades, tones, and tints. They are often chosen for their ability to evoke emotions or convey specific meanings.
