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