You can probably email RiderGraphix through their website and request a sample piece of the material in the color(s) you are considering. That way you can determine if it will match hockey stripe material. That's what I did so I could decide if I wanted to go with the Dark Charcoal Metallic or Silver Metallic. I had the samples within a couple of days and was able to see what they looked like against the Victory Red in different lighting conditions.
The hood stripes came from Ridergraphix.com. With a bit of help from my wife, we installed them, along with the matching bowtie blackout decals in a couple of hours on a Saturday morning. It really wasn't all that hard to do as long as you take your time and pay attention.
I think they'd look pretty good with the hockey stripes.
