Besides Jonas and Gabriel, who has pale eyes?

Jonas and The Giver both have pale eyes.  So do Gabriel
and a young Six girl named Katherine as others have mentioned.  Rosemary also had pale
eyes.  It is likely that they all are related, and they all have special
abilities.

It can be reasonably inferred that the pale eyes
are a genetic trait.  Jonas does not like his pale eyes because they make him different,
and people in the community are trained to reject and fear differences.  However there
seems to also be a link between pale eyes and the capacity to See Beyond, or the special
power to see colors and receive memories.
