Prefect Badges

In PS Percy was a prefect, it says his badge was SILVER.
In OotP when Ron and Hermy get their badges, it says theyre red and gold!!
why the change??

maybe it was a mistake

Maybe they change the badges every year.

Yah that is a good piont. maybe they just want a new look!

lol

yeah i think they like change em every year or dumbledore decided on a new look but jk rowling didn't mention it or something like that
