I tried to reproduce a TV effect for C2 with phosphour glow and shadow mask the other day. Came up with this:
This is how I set it up:
Png image to simulate the shadow mask with Overlay Blend applied. This goes on top of everything else.
Blur Horizontal 10 on entire layout for a sense of color bleeding like you get with phosphour glow.
Sharpen 10 on entire layout.
HSLAdjust on entire layout with Saturation 105-110 and Luminosity 93.
Sampling -> Linear in Project Settings.
You'll be needing WebGL obviously. The entire canvas needs to be scaled to at least 2X and the CRT2 image needs to be set to 0.5 scale to get it all to look right.
