You might have luck with something like this:

What are you working on?
 
If it's not used outdoors you can color bondo with a universal tinting color. You would have to use a fiberglass resin hardener to harden it because the red hardener added to black would make a dark brown.

Oh sure … here's my whole question: Is black-colored body filler available anywhere that can be sanded just like bondo?

You could probably get significantly more help if you told what type of plastic it is, which makes a HUGE difference on what will bond to it. The performance is also affected by exposure to weather, what sort of stress it its under, such as twist, compression tension, etc. if there is rust adjacent to the repair area. From the years that I have been reading these forums I have found that the amount of diversity in other reader's life experience is just immense. So when I have a question on a project, rather than ask for what I have concluded I have narrowed my plan down to. I will tell exactly what I am working on so that readers can actually apply their experience and knowledge to the whole problem rather than a sliver of it. On the TV quiz shows contestants have a much better chance at getting the correct answer after they are given more clues.
 
For that application I would use epoxy for plastic and once you get it repaired restore the color with paint such as fusion which is made for plastic. You could dispense some out of a rattle can and mix different colors until you match it and apply it with a soft artist brush.

This is sound advice and more along the lines with what I was thinking from the beginning. I don't think the OP will be happy with the repair without using some paint.

Yeah, need to use black matte spray paint to finish. Which is why I wondered about black-colored filler in the first place. Would make a better job if it was black underneath the paint. Stephen, sounds like you've done this before. It's basically an art project -- lol (like you I do artwork as well). I've restored a few before.

I've used both bondo and epoxy (for plastic) before and actually for this I prefer the bondo because it is softer and shapes easier. Sometimes the epoxy is harder than the plastic and that makes it tougher to work with appearance wise. I am using epoxy to mend the cracks.
 
I'm primarily a cabinetmaker and furniture refinisher. There is times when I need to fill a knot hole or a gouge on an antique and will mix a universal tinting color in the bondo and use for wood putty. A universal tinting color is the colorant a paint store has in their machines to mix paint. It will mix into bondo just fine but has to be done prior to adding hardener. I just don't know what it would do to the integrity of the bondo if someone were to use it outdoors.
