CIELUVruumi

CIELUVruumi is a color space derived from the CIELUV color space. It is designed to represent human perception of color, particularly in relation to uniformity. The 'ruumi' component is a hypothetical third chromatic dimension that aims to further enhance perceptual uniformity beyond what CIELUV offers. Researchers have proposed various mathematical models for CIELUVruumi, attempting to map colors in a way that equal distances in the color space correspond to equally perceptible color differences. The goal is to create a color space where color differences can be numerically evaluated with greater accuracy, making it useful in fields such as colorimetry, computer graphics, and industrial color management where precise color matching and difference assessment are critical. While CIELUV itself is widely adopted, CIELUVruumi remains a more theoretical or developmental concept, with its practical implementation and acceptance still evolving. Further research is ongoing to refine its definition and validate its perceptual accuracy against empirical data.
