Color models are systems used to represent and describe colors in a standardized way. The most common color models include the RGB model, which uses red, green, and blue light to create colors, and the CMYK model, which combines cyan, magenta, yellow, and black inks for printing. Each model serves different purposes, with RGB primarily used in digital displays and CMYK in print media. Another important color model is the HSV model, which stands for hue, saturation, and value. This model is often used in graphic design and image editing because it aligns more closely with human perception of color. Understanding these models helps artists, designers, and photographers accurately reproduce and manipulate colors in their work.
