The color model in computer graphics is a mathematical method for describing and representing colors, and is used to accurately generate, process, and display colors in computers. Common color models include:
RGB model: Based on the additive color mixing principle of the three primary colors of red (R), green (G), and blue (B), it is widely used in monitors, televisions, and other devices, and various colors are combined by adjusting the brightness of the three primary colors.
CMYK model: Based on the subtractive color mixing principle of the four-color inks of cyan (C), magenta (M), yellow (Y), and black (K), it is mainly used in the printing industry to reproduce colors by superimposing inks.
HSV/HSL model: HSV stands for hue, saturation, and value, while HSL replaces value with lightness. They are more in line with human intuitive perception of color and facilitate color selection and adjustment.
These color models have their own characteristics and are suitable for different application scenarios, and together they form the basis of color processing in computer graphics.
