Link color question

[Chmex21]

Not sure if this goes here, but how do i change it just for the links and the text. Meaning phpportals uses the {linkcolor} variable, now I want to go to go were vbulletin calls the {linkcolor} or what ever vaiable it uses and change it manually. so that i don't have to change it in vB admin and phpportals will continue to use the variable and vbulletin will use what i speicfy in the template. Not sure which template it would be or what the variable would be. When i do a search for the varible {linkcolor} I get one result back in the headerinclude. When i change that it also changes for phpportals. is there any other way?

Thanks in advance for the help.
