Script or plugin to change folder colours in apple mail?

Does anyone know if it's possible to colour code your folders in apple mail (version 2).

It is our standard mail app at work and I seem to spend half my e-mailing life trying to find the correct folder to file away my e-mails.

I have almost 50 sub folders and it would be really useful if I could change the colour of a few of them.

anyone know if there is a plugin or script available to do this?

Thanks!

 

I guess that's a no then.

It's a pity this feature was left out of mail when it is standard in the finder.
Colour coding folders really helps to streamline workflow, seems a bit odd to allow it in some areas and not others.
