[NME]Is there a better way to make color self-illuminated?

I want to make an energy shield effect, and hope its lighting part looks like this:

Now i have this kind of nosie texture:

Based on it, i used remap block to take me one step closer to this effect:

But it added some gray color near the noise edge(lighten the base color will be more obvious)

So i’m wondering, is there a better way to implement this self-illuminated effect?

From this PBR tutorial, i found a glow mask solution, i’m working on it.
