PUPMCR: an R package for image-based identification of color based on Rayner's (1970) terminology and known fungal pigments.

ABSTRACT: Fungi are eukaryotic organisms grouped based on different traits of their morphology. In 1970, R. W. Rayner published A Mycological Colour Chart to provide a standardized system for identifying color in fungi. While its terminologies have contributed a standard way of color matching for taxonomic diagnoses, this method using the personal color perception of the observer does not guarantee accuracy. Considering the diversity of fungi, visual color matching is expected to be challenging without a standard assisting instrument. In this study, the R package PUPMCR is developed to approximate the color name and associated pigments of fungal species based on the pixel coordinates of its uploaded image. This software utilizes CIELAB and RGB color spaces as well as Euclidean and Chi-square
