How do I give a completely black object a glow effect? I am trying to give an all-black object a glow effect. Is this achievable? I have seen how to create glow effects using emission and world bloom, however, this obviously has no effect on a black object.

I am using Blender 2.82 and am rendering with Eevee in case that info helps. Thank you in advance for any assistance you can provide and please note that I am day 1 into Blender.



Here is an example of the effect I am trying to achieve:
It looks like you want Eevee for easy bloom?
You can repurpose an edge lining technique for it.  Give your object two materials and a solidify modifier with a material offset.  Make one material black, and for the other, give it emission for backfaces, but transparency for front faces:

Note that you'll need to enable some sort of blending (alpha clip is fine) and make sure you're not culling bakfaces, in material settings as shown.
There are a number of additional ways you could achieve this, constraint-placed shadowing meshes, render layers, and probably others.  But this is previewable, simple enough, and should get you what you're after.
