Tavoiteväriavaruudetta

Tavoiteväriavaruudetta refers to a conceptual model in color science and colorimetry, specifically in the CIE 1931 color space. It represents the range of colors that the average human eye can perceive under specific viewing conditions. The term is derived from the Finnish words "tavoite" meaning "target" or "goal," and "väriavaruudetta" meaning "color space."

The CIE 1931 color space is a three-dimensional representation of colors, with the three dimensions being the tristimulus values X, Y, and Z. These values correspond to the responses of the three types of cone cells in the human eye to different wavelengths of light. The tavoiteväriavaruudetta is defined as the subset of this color space that can be perceived by the average human observer under ideal viewing conditions.

The boundaries of the tavoiteväriavaruudetta are determined by the spectral locus, which is the set of colors that can be matched by a mixture of three primary colors. The spectral locus forms a horseshoe-shaped curve in the CIE 1931 color space, with the straight line connecting the ends of the curve representing the purples. The tavoiteväriavaruudetta is the area inside this curve and below the line representing the maximum luminance that the average human eye can perceive.

The concept of tavoiteväriavaruudetta is important in color science because it provides a standard reference for comparing the color rendering abilities of different lighting systems. A lighting system that can reproduce the colors within the tavoiteväriavaruudetta is said to have good color rendering properties. The tavoiteväriavaruudetta is also used in the development of color management systems, which are used to ensure consistent color reproduction across different devices and media.
