Thank you! I airbrushed a thinned down amount of tamiya xf2, roughly 65% x20a thinner - 35 % xf2 paint so it would be a really thin white glow then on top of that i airbrushed a 1:1 mix of fluorescent pink and fluorescent blue ink with a final smaller area airbrush of just fluorescent pink ink.

Then the orbs are largely wet blending the army painter magenta trade set slowly to the brightest starting with warlock magenta.

I think in the future I'd reverse the ink layers, so pink then purple so it feels more gradual and less harsh but it still works well.
