Description: Provides a standardized and reproducible framework for characterizing
    and classifying discrete color classes from digital images of biological organisms.
    The package automatically determines the presence or absence of 10 human-visible
    color categories (black, blue, brown, green, grey, orange, purple, red, white, yellow)
    using a biologically-inspired Color Look-Up Table (CLUT) that partitions HSV color space.
    Supports both fully automated and semi-automated (interactive) workflows with complete
    provenance tracking for reproducibility. Pre-processes images using the 'recolorize'
    package (Weller et al. 2024 <doi:10.1111/ele.14378>) for spatial-color binning, and
    integrates with 'pavo' (Maia et al. 2019 <doi:10.1111/2041-210X.13174>) for color
    pattern geometry statistics. Designed for high-throughput analysis and seamless
    integration with downstream evolutionary analyses.
