Glowing shadow intersection with lights

How can I get a glow on where the light and shadows intersect? Check this video at 0:10

Notice how on the wall, the red brick part on the left is causing the intersection with light to glow red and the yellow part of the wall on the right is causing the intersection to glow yellow.

I don’t think this is just a simple global glow post process (is it?)

That’s just the bloom post process, the light bouncing off the wall is bright which makes it glow. UE4 does this very well.
