Its not about matching the color when it comes to cue repair. You NEED to match the playability, as well as the color. In the ring billets, it isn't as important as long as you are using the same black plastic around the ring pack. I've seen some people use phenolic or black Juma and those materials have different characteristics.
It may be splitting hairs but I feel this is an important part of repairing cues. I hope this helps.
