The sources provide an extensive technical explanation of the OKLab color space and its implementation within web technologies, primarily focusing on the Chromium (Blink/Skia) rendering engine. OKLab is presented as a modern, perceptually uniform replacement for older spaces like CIELAB, designed to improve the accuracy of color adjustments, blending, and gradient generation by providing consistent lightness and hue stability across the color spectrum. The text details how OKLab and its cylindrical form, OKLCH, were integrated into CSS Color Module Level 4 to enable wide-gamut color specification and smooth interpolation, requiring significant changes to the browser’s internal color handling, storage (using high-precision floats), and the use of Skia for hardware-accelerated gradient calculation in the correct perceptual space. Ultimately, the integration of OKLab/OKLCH is presented as a crucial step toward creating a more accessible and aesthetically accurate web.
