Dragon/Firelizard/Wher eye colors and sounds

Pern dragons show their emotions in more than just their stance and bearing. A dragon's multifaceted eyes spin, the speed indicating the intensity of the emotions. Below are the possible eye colors, and their meanings

Red: Anger, Hunger(Active Appetite), Fear, Mating, Pain, Excitement.
Red/Orange: Mating, Alarm, Eagerness, Arousal.
Orange: Uncertainty, Suspicion, Anger, Mating, Alarm, Hunger, Agitation, Panic.
(It would appear that Red and Orange are quite interchangeable, and the same could be said for Green and Blue, which are "Happy", "Content", "Pleasure", (and lots more words like that)and "Normal" colours.)
Yellow: Anxiety, Fear, (Reproachful?) Worry, Excitement
Pale Yellow: Concern.
Green: (See above) Delight, Tranquility, Placidity.
Blue: (See above) Longing, Interest, Mischief, Excitement.
Purple: Worry.
Lavender: Stress.
Grey: Great Worry/Stress/Sadness/Pain (Grey tones come to a dragon's hide too).

If a creature is fully or partially Albino (albino covers eyes) the eyes are always ichor green, though it might gain hints of color if the emotion is particularly strong.
