Not sure about matching colors...I gather the REC guides you are using are a silver metallic?
I'd suggest trying out the American Tackle line...I've used two of their guides (both available in a 20). There's the Titan line (titanium body with a black ceramic ring), and then there is another line of their's, the name of which I forget, that is a stainless frame with a blue ceramic ring. I've used both, with choice based on matching colors of blanks / thread...the Titans are lighter, and tend to have a bigger ID for a given ring size...Probably what I will stick with from here on out..
These guides are widely available....
