You can try using the new Cryptomatte feature in 2.8 which will allow you to separate objects or materials in your render, I'm not very familiar with it myself yet but here is a quick test I did to get a soft glow around an object with the option to change it's color. Check out this video for more tips on how to use the Cryptomatte. [this video] . [LINK]

Blender 2.8 Cycles has Cryptomatte feature ( [this video] ) which is more versatile, so you do not need object/material pass index.
Cites White Raven · 2020-08 · Blender Stack Exchange · on “Why do we need Composite node?”
[this video] - I watched this video and wondered - why Composite node exists? What is it for and what does it do? After all, we can work through a viewer node and export the result.
