Any idea what is going on here? It's an Atari version 2 PCB if it matters.

Check data outputs of character graphics ROMs. I do not know which off the top of my head.

Actually, on second glance, they look correct, but missing the green element. That's strange and unusual, since Dig-Dug looks fine.
 
bump, hoping to have time this weekend to burn a new set of roms and see if that fixes it. any other ideas are appreciated.
 
Update: i burnt a new set of roms, removed, cleaned and re-seated the rest of the socketed chips, and swapped z80s with no change. I did notice when Fygar shoots fire he changes to the correct colors. Here is a better video (sorry for the hum bars, that's the best i could get):

 
Anything showing up in Self Test?

I would start on pages 14 - 16 (Sheet 7b, 8a, 8b) of the schematics and look at those chips.

If you have a spare board or another board that uses the same customs you could swap the customs to see if there is any change.
