BB Color - code appears in posts
 

We had to take away members ability to change the font color in their posts because people were abusing it. They were using a white font (against white background) to hide their posts from Admins.

When we disabled BB color, we noticed any posts that previously had color, now look like this:

[[COLOR=yellowgreen]] This is a test. This is a test[[/COLOR=yellowgreen]]

It doesn't look good to have color code in previous posts. Is there any way to fix this without turning BB color back on?
