Relating to or characterized by normal coloration or pigmentation, especially in biological tissues.
From Greek 'eu-' (well, good) + 'chroia' (color or complexion). The suffix '-ic' makes it an adjective describing something with proper or good coloring.
Biologists use 'euchroic' to mean organisms with normal color patterns, which seems simple until you realize it's the opposite of 'albino'—language helps us see nature's diversity!
