Css thread color style

[Set3sh]

I would like to do this:
If a thread title contains [Accepted] I would like that the threads title color to change to green, if it contains [Rejected] to change the color to red and if contains the tag [Pending] to change to yellow.
I was thinking to do it like this in additional.css:
a switch: case 1 [Accepted] a.title {color:green;} | case 2 [Rejected] a.title {color:red;} | case 3 [Pending] a.title {color:yellow;}

I know it's php/css and that c/c++ doesn't quite fit here, but I'm open to suggestions.

Thank you
