You use regular epoxy but dye it with epoxy dye.
You'll want to use the slowest setting epoxy you can find.
Just go to the big auction site and you'll find anything you need. Type in epoxy dye.

i use 2-ton epoxy with black dye mixed in. tedious and messy but pretty cool. i make short sections instead of 6 or 12 " sections....just easier to deal with.i got the dye from a knifemakers supply. i have some blue dye if you want it. pm me if interested.

I use liquid dyes made for laquer based paints.  Any tint should do.  Maybe even black india ink.  Use only a tiny bit, the less the better.  
Use a vacuum pump for pulling a vacuum on it, just hook some fish tank tubing to the tube, then to vacuum pump.  it'll bring the epoxy into the tube. There is not a good way to promise no air voids, it just takes practice.  Pull the least vacuum it requires to pull the epoxy through the tube.  Keep a small vacuum in the setup until the epoxy sets.
I am talking about the handheld vacuum pumps that you can bleed brakes with on a car.
Mityvac, I believe, is the name of mine.
