The brilliant emerald green is preferred in the show ring. No yellow is allowed in the eyes of adults. The eye shape is almost round, just oval enough to show an oriental slant. Eyes are set one eye width or more apart. The Russian Blue has a high fore-head, with the top of skull flat and narrow, smoothly curving into the back of the neck.
Face is broad at eye level and looks even broader due to thick fur at side of head.
Medium length straight nose looks upturned from almost any view except profile due to light reflection. Neck is long but does not appear so in repose, due again to thick fur. There are seven planes on the head each counted separately, giving an almost serpent-like profile when the ears are held down. The ears are rather large and wide at the base, as they are tall, and set far apart as much into side as top of head. Ears look pointed, as hair tufts finish off where the slightly rounded tips stop.
