Színmodell

A színmodell, or color model, is a mathematical model describing the way colors can be represented as tuples of numbers, typically as three or four components. These models are used in various fields, including computer graphics, image processing, and color science. The most commonly used color models are the additive and subtractive models.

The additive color model, also known as the RGB model, is based on the principle of light mixing. In this model, colors are created by adding different intensities of red, green, and blue light. This model is widely used in digital displays, such as computer monitors and televisions. The RGB model is typically represented as a three-dimensional space, where each axis corresponds to one of the primary colors.

The subtractive color model, also known as the CMYK model, is based on the principle of pigment mixing. In this model, colors are created by subtracting different amounts of cyan, magenta, yellow, and black pigments from white light. This model is commonly used in printing and painting. The CMYK model is also represented as a three-dimensional space, with each axis corresponding to one of the primary colors.

Other color models include the HSL (hue, saturation, lightness) and HSV (hue, saturation, value) models, which are based on the perception of color by humans. These models are often used in image editing software, as they allow for more intuitive manipulation of colors.

Color models are essential for the accurate representation and manipulation of colors in various applications. By providing a mathematical framework for describing colors, these models enable the development of algorithms and techniques for color correction, color conversion, and color management.
