Hope that's alright. :)
I have the exact RGB codes. I even have the HSL ones or whatever they're called, yet, quartz is pissing me off. It does something to the color so that it doesn't look anything like what it's supposed to. Grrr... All my alphas are up but it still makes it semitransparent.
I believe oUF_p3lim has casting bar support as i've been looking at it for suggestions on how to make it work on my layout.
Edit: Damn you p3lim :P
