Ginny: green eyes or brown eyes?

No: HPFGUIDX 79851

In CoS, p. 40 (US, paperback), as Harry passes Ginny's room in 
the Burrow:

"On the third landing, a door stood ajar.  Harry just caught sight 
of a pair of bright brown eyes staring at him before it closed with 
a snap.  'Ginny'......"

While listening to CoS on audio tape (Jim Dale's reading), he 
clearly states "bright green eyes" in this same passage.  If this is 
a mistake, I'm surprised that it would not have been caught and 
corrected.

Which is it, brown or green?
