The recipe and methods I use to paint bulk EC models. Recipe is based off regular models (space marine, noise marine, etc) but colours, ratios and general aesthetic works across bigger models.
General rules are:
1. Majority of model is pink
2. Second most colour is black
3. Bronze/Gold for Trims and specific details
4. Grey metallics for basic stuff (chains, studs, etc)
5. Small amount of bright colours to make things pop (greens/yellows/neon reds) on things like eyes, plasma coils, backpack decorations, etc)

RECIPE INCOMPLETE CURRENTLY

1. Airbrush black primer over model
2. Airbrush Wine Red over parts you want pink. I usually do chest, right shoulderpad, right leg, head, top of backpack.
