Ok gang, I'm still in the preliminary stages of graphics design here, but I was wondering if anyone out there knew the RGB colors to match these types of buttons. I want some elements of my CPO and side art to match the buttons with respect to color. I'm going to use both blue and red ones...

...and I want stuff that I print (or pay to get printed) to match the buttons as closely as possible. Sometimes what a color looks like on screen and what it looks like printed are two different things. In my case, obviously, I'd be looking for a matched
printed color.

Any ideas?
