As Ottosson explained, [1] he chose the name Oklab because the model does an OK (adequate) job and is based on the three color-space coordinates L, a, and b.

Nov 18, 2025 · // Takeaway: before manipulating color for sRGB (gamma-corrected or gamma compressed), convert it to linear RGB or a linear color space. Then do the manipulation, then …

Dec 23, 2020 · This post has introduced the Oklab color space, a perceptual color space for image processing. Oklab is able to predict perceived lightness, chroma and hue well, while being …

Dec 1, 2023 · In OkLab, the X component represents lightness (0 to 1), the Y component represents green/magenta chroma (-0.5 to 0.5) and the Z component represents blue/yellow …

What is Oklab color space? A color in Oklab is represented with three coordinates, similar to how CIELAB works, but with better perceptual properties. Interoperable with the rgb crate. A Red + …

Nov 7, 2025 · oklab() works with a Cartesian coordinate system on the Oklab color space — a- and b-axes. It can represent a wider range of colors than RGB, including wide-gamut and P3 colors. …

The Oklab color space is a uniform color space for device independent color designed to improve perceptual uniformity, hue and lightness prediction, color blending, and usability while ensuring …

OKLab, by Björn Ottosson is a CIE Lab replacement which transforms D65-adapted, whitepoint-relative XYZ to an LMS space, then uses a cube-root nonlinearity to produce an opponent …

The sRGB gamut represented within the Oklab color space. A new perceptual color space that claims to be simple to use, while doing a good job at predicting perceived lightness, chroma …

Dec 18, 2024 · The gamut is the RGB cube transformed into oklab space. Amazingly, the biggest inscribed circle along the luminance axis in the OKlab gamut occurs at ℓ ≈ 75%.
