perusvärimallien

Perusvärimallit, also known as primary color models, are fundamental systems used to represent and reproduce colors. They are based on the idea that a limited set of colors can be combined to create a wide spectrum of other colors. The specific primary colors used depend on the medium and the intended application.

Two main types of perusvärimallit exist: additive and subtractive. Additive color models, such as the RGB (Red, Green, Blue) model, are used for light-emitting devices like monitors and televisions. In this model, combining red, green, and blue light in varying intensities produces other colors. Mixing all three at full intensity results in white light, while the absence of all three creates black.

Subtractive color models, like CMY(K) (Cyan, Magenta, Yellow, and often Key/Black), are used in printing and pigment-based applications. These models work by absorbing, or subtracting, certain wavelengths of light from white light. Cyan absorbs red, magenta absorbs green, and yellow absorbs blue. When these colors are combined, they absorb more light, leading to darker colors. Mixing cyan, magenta, and yellow theoretically produces black, but in practice, a separate black ink (K) is often used for better depth and detail. The choice between additive and subtractive models is crucial for accurate color reproduction across different technologies.
