New Oklch+ color space improves perceptual difference prediction

Researchers have developed Oklch+, an enhanced color space designed to more accurately predict color differences than existing models like Oklab. This new system uses a three-parameter extension, incorporating power transformations and compression functions to better align with human perception of color. Evaluated against established datasets, Oklch+ demonstrates a significant improvement in accuracy, closely matching the performance of the more complex CIEDE2000 standard while using fewer parameters. AI

IMPACT This research could lead to more perceptually accurate color interpolation and design tools, potentially impacting AI-driven image generation and editing.

    Oklch+: A Three-Parameter Extension of Oklab for Improved Color Difference Prediction

    arXiv:2606.05255v1 Announce Type: cross Abstract: Oklab and its cylindrical representation Oklch are widely adopted in interpolation and design workflows as perceptually motivated color spaces, but their color difference prediction accuracy falls short of CIEDE2000. We propose Ok…
