Citadel Spray Paint: Macragge Blue 400ml

A Foundation Worth Building On

Macragge Blue is one of the most recognisable colours in the tabletop hobby — the deep, rich blue that forms the backbone of the iconic Ultramarines colour scheme and a reliable foundation for countless other blue-based armies and projects. This 400ml aerosol spray primer lays down a smooth, even base coat in a single pass, saving time and getting your models to the painting stage faster than brush-priming ever could.

What This Spray Does

Citadel's spray primers are formulated specifically for miniature plastics — they bond directly to bare polystyrene, resin, and metal without obscuring fine surface detail. Macragge Blue applies as a true base coat colour, not just a neutral primer, which means models intended for blue schemes can skip the separate base coating step entirely and go straight to layering, shading, and highlighting. The 400ml can covers a substantial quantity of models — ideal for batch painting squads, priming a Combat Patrol's worth of Space Marines, or laying down a uniform basecoat across a mixed unit of infantry and vehicles in one session.

Who Should Pick This Up

Painters working on Ultramarines, Space Wolves, Blue-toned Thousand Sons, Tau, or any other blue-primary scheme will get the most direct use out of Macragge Blue — it is the dedicated base coat spray for the Ultramarines range and a staple of Games Workshop's recommended painting guides. That said, this is a strong general-purpose blue primer for any painter who wants to skip brush-on base coating for large batches. New hobbyists benefit particularly from aerosol primers: they provide a consistent, even surface that brush-on base coats rarely match on a first attempt. Apply in short bursts at roughly 25–30cm distance in a well-ventilated area, and avoid spraying in high humidity or cold temperatures to ensure the best finish.
