Green plasma effect (brush only)

Water down the paint and apply mostly to the recesses. Leave most of the black on the coils black, you're only covering around 20% in white.

Cover all the white and coil recesses in Dark Green.

Apply white again but on less area leaving most of the Dark Green visible.

Cover all the white in Scorpy Green.

Add a little bit of white where you want it to be really punchy.

Paint the top of the coils black and touch up where you accidentally covered with green or white.
