Reset username colors?

Hi, I recently introduced a new main style on my forum which makes alot of username look bad or unreadable.

How can I set all names to default style color?

[eNforce]

anyone?

Alas, sorry for bumping a terribly old topic, but I wish to know the same thing.

I would like to know hot to reset all usernames and if possible all purchasable items without erasing user point counts.
