Detailed Description

Color difference metrics for qualpal.

Provides classes and functions for computing perceptual color differences using standard metrics (DIN99d, CIE76, CIEDE2000). These metrics are used for palette analysis, selection, and color distinguishability evaluation.

All metrics are callable objects (functors) and can be used with colorDifferenceMatrix() and palette generation algorithms.
