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

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 Oklch+, a three-parameter extension of Oklab comprising a power transformation on the L-axis and a Naka-Rushton compression on the C-ax
