Army Painter: Colour Primer Base Spray: Ultramarine Blue

A Solid Blue Foundation, Ready for the Brush

Starting with the right primer makes every paint job faster and more consistent. Army Painter's Ultramarine Blue Colour Primer lays down a smooth, even basecoat in a single pass — skipping the separate prime-then-base-coat step entirely. The pigment is rich enough to hold its own as a foundation colour, giving you a consistent blue surface that accepts layers, highlights, and washes cleanly. For armies built around blue armour, vehicles, or robes, this spray cuts hours off batch-painting a full force.

How It Fits Your Workflow

Colour Primers are Army Painter's take on the combined primer-and-basecoat — one aerosol that both prepares bare plastic (or metal or resin) for paint adhesion and delivers an opaque, even colour foundation in the same step. Ultramarine Blue is a mid-tone, saturated blue — deep enough to anchor darker shading washes but light enough to show highlights cleanly without extreme contrast. It is compatible with paints across all major hobby brands, so you are not locked into any single paint range once the primer coat is down. Apply in short, even passes at arm's length in a well-ventilated space, ideally at temperatures between 15°C and 25°C for best results.

Who Should Reach for This

Any miniature painter building a blue-dominant scheme will find this spray a genuine time-saver. It is especially useful when batch-priming large units where consistency across every model matters. Painters newer to the hobby will appreciate that a Colour Primer removes one step from the workflow — prime and basecoat in a single session, then go straight to shading and highlighting. Experienced painters running efficient assembly-line painting sessions will value the speed. It works across any miniature wargaming system — Warhammer 40,000, Age of Sigmar, Warmachine, and beyond.
