Icterine — The word “icterine” is derived from the Ancient Greek word that literally meant “jaundiced”. Despite its grim origin, however, the color Icterine is a bright, cheerful shade of sunny yellow with a warm golden undertone and a pleasant disposition overall. A few species of yellow bird owe their names to this particular shade, including the bright yellow icterine warbler and the equally cheerful icterine greenbull.
