Okay, So I figured out how to fix the syntax highlighting if anyone is interested.
So using finder, locate your RC and open up its contents. Then once you get to graalcolors.xml, just open it with any default text editor.
PHP Code:
~/Applications/RC.app/Contents/Resources/language-specs/graalcolors.xml
Then add the following line into graalcolors.xml, just make sure you keep it inside the style-scheme brackets.
PHP Code:
<style name="def:string" foreground="#C000C0" />
Enjoy (Strings was the only thing that bothered me, there's still a couple other fixes that could be done)!
