| | | | | [AI summary] The article explores the concept of color spaces, focusing on how colors are represented and manipulated in different systems. It begins by explaining that colors are abstract concepts without inherent spatial relationships, but they can be organized into coordinate systems for practical use. The CIE XYZ color space is highlighted as a foundational model that linearly represents light intensity, enabling precise mathematical solutions for color mixing and matching. However, predicting how humans perceive color differences remains a complex challenge, as it involves the nonlinear and subjective nature of human vision. The article then introduces Oklab and OKLCH as modern color spaces that aim to model perceptual uniformity by isolating lightness,... | |

| | | | | The saturation control of pretty much all image processing software is an unfortunate misnomer, to say the least. It actually controls either the chroma in Ych-like spaces (computed from CIE Yxy 1931, Yuv or YCbCr spaces), or some remote idea of saturation as used by HSL spaces, which are essentially a polar rewriting of RGB coordinates (usually expressed in sRGB space). The "saturation" as defined by the HSL space has been proven times and times again to hold no perceptual meaning and finds its origin i... | |
