Värvide

Värvide is a term used in color theory and design to refer to color values—the attributes that define a color and distinguish it from others. In practice, this encompasses aspects such as hue (the type of color), saturation (intensity), and brightness or lightness (the perceived amount of light). The concept of color value is central to both artistic practice and digital imaging, where precise numerical representations are needed to reproduce colors consistently across media.

In color models, different components encode color values in various ways. In RGB, values are assigned to red, green, and blue channels, and the resulting color emerges from their combination. In HSV and HSL, hue is fixed while saturation and value (or lightness) control vividness and brightness. CMYK uses ink concentrations to achieve color values in printing. Perceptual color spaces, such as CIELAB, aim to model color in a way that aligns more closely with human vision, enabling more intuitive comparisons of color values.

Numeric representation of color values is a practical concern in computing and publishing. Common formats store channel values as integers (for example, 0–255 per channel in 8-bit color) or as floating-point numbers in a 0.0–1.0 range. Gamma correction, device calibration, and color management systems help ensure that color values appear consistent on different displays and printers.

Applications of värvide include digital art, photography, web design, branding, and accessibility. Proper management of color values supports legibility, contrast, and visual harmony across diverse viewing conditions.
