A standardized visual reference depicting the range of feline eye colors assists in identifying specific hues and variations. This reference typically displays colors arranged systematically, often from lightest to darkest or grouped by similar tones, and may include annotations describing genetic influences or age-related changes.
Such a resource proves valuable for breeders in predicting offspring coloration, veterinarians in assessing ocular health, and researchers studying feline genetics. Historically, documentation of eye color played a role in establishing breed standards, and continues to contribute to our understanding of genetic expression in domestic cats. Precise color identification can also aid in distinguishing individual animals, particularly in research settings or multi-cat households.
