Need help with fading colors (BBcode)

[Hubcool]

What I'm trying to do is use the fading effect of BBcode, example : A word that being blue and fade to finish in red.

I hope you know what I mean and you can help me I saw some people do it, just can't remember where and I'm trying to find out how :/
