intensely green when i am very angry, upset or deeply moved in some way.
i'd be very interested to find out a scientific explanation.
It has to do with the way your brain perceives color relative to its surroundings. Look at a "white" background on your computer monitor for
example, and it will appear "white" relative to the surrounding colors. But hold a piece of clean "white" paper against your screen, and what
looked white before will appear more of a gray. Blue and green are very close to one another. You've probably encountered instances where something
looks blue sometimes and green other times.
In the case of your eyes, the "background" being changes by your mood is the amount of blood in your face. When you're angry, moved, etc. more
blood goes to your face, making it more red. Thus, the relative color of your eyes appears to change.
If you hold your breath try to exhale really hard for a few moments, you should be able to effect the change deliberately. Just don't do it too long,
or you may pass out.
