värimalleet

Värimalleet, often translated as color models or color spaces, are systems used to represent and organize colors. They provide a standardized way to define, communicate, and reproduce colors consistently across different devices and media. The primary purpose of a color model is to create a reproducible framework for color specification.

Common color models include additive and subtractive models. Additive color models, such as RGB (Red, Green, Blue), are used for displays like computer monitors and televisions. In RGB, colors are created by adding different intensities of red, green, and blue light. Mixing all three at full intensity produces white, while no light results in black.

Subtractive color models, such as CMYK (Cyan, Magenta, Yellow, Key/Black), are used in printing. These models work by subtracting light from a white surface. The inks absorb certain wavelengths of light and reflect others. Mixing cyan, magenta, and yellow theoretically produces black, but in practice, a separate black ink (K) is used for better depth and economy.

Other color models exist for specific applications. HSL (Hue, Saturation, Lightness) and HSV (Hue, Saturation, Value) describe colors based on their perceived visual characteristics, making them intuitive for artists and designers. CIELAB (or Lab) is another perceptually uniform color space designed to be device-independent, meaning it aims to represent colors as humans see them, regardless of the technology used to display or reproduce them. The choice of color model depends heavily on the intended application, whether it's digital display, print, or scientific color measurement.
