Grey is much easier to source and most manufacturers tend to make that constantly so once you find a shade that matches what you need then its easier to keep up a supply especially if you find one from a major brand such as Ziro etc...
One other thing to consider when printing track etc... is make sure you orientate it so that your layer lines are such that you get the highest mechanical strength. For example if you wanted to create a fairly long piece you might consider printing it upright or diagonal for example. But this would potentially lead to mechanical weakness as the layers would be on the thinner part of track if that makes sense which may result in it snapping if bent too far. If possible it is always best to print the track flat on the bed for strength
