Black vs White vs Gray Primer
The decision that affects every color you paint afterwards, made before you open a single pot.
The short answer
Gray is the best default: light enough for colors to read properly, dark enough that recesses still read as shadow. Black gives free shadows and makes light colors much harder. White gives bright colors and no shadows. Contrast and Speedpaint require a light primer and do essentially nothing over black.

The comparison
| Black | Gray | White / bone | |
|---|---|---|---|
| Shadows | Free — recesses stay dark | Partly free | None — you place all of them |
| Bright colors | Hard. Yellow and white need several coats | Reasonable | Easy, one coat |
| Drybrushing | Excellent — maximum contrast | Good | Poor — no dark to contrast against |
| Contrast / Speedpaint | Does not work | Works (light gray) | Works best |
| Shows mold lines and gaps | Hides them | Shows them | Shows them clearly |
| Metallics | Best — dark silver covers in one coat | Good | Poor — metallics look washed out |
| Forgiving of thin coverage | Yes — gaps read as shadow | Fairly | No — gaps read as missing paint |
| Best for | Dark, metallic, grimy schemes | A first army, mixed schemes | Bright schemes, one-coat paints |
Why gray is the default answer
Because it is the only one of the three that is not actively hostile to anything.
Black makes bright colors a slog. White makes shadows your problem and metallics look anemic. Gray is mediocre at both and bad at neither, which for a first army — where you do not yet know which techniques you will favor and your scheme may change — is exactly the right property.
There is a second reason that gets less attention: gray shows mold lines and gaps while you can still fix them. Black hides them until the basecoat goes on, at which point the seam you did not scrape is suddenly obvious and the model is half painted.
When black is right
Three cases, and they are real cases rather than preferences:
- Your scheme is dark. Black armor, black robes, dark metal. Priming black means you have basecoated most of the model already.
- You intend to drybrush. Drybrushing over black is the highest-impact, lowest-skill technique in the hobby, because the contrast between the dark recess and the light edge does all the work. See drybrushing.
- The model is mostly metal. A dark silver covers black in one coat and then takes a wash beautifully — see metallics.
Black is also the most forgiving primer for a nervous beginner, because any spot you miss reads as shadow rather than as an error.
When white or bone is right
- Your scheme is bright. Yellow, orange, bright red, white, pale skin. Over black these are genuinely miserable; over white they cover in one coat.
- You are using one-coat paints. Not a preference. Contrast and Speedpaint are transparent and produce nothing over black. Contrast specifically wants Citadel’s Wraithbone or Grey Seer — see Contrast explained.
- You want to see what you are building. White shows every gap, seam and mold line, which is useful before you paint and demoralizing afterwards.
Bone, incidentally, is a warm off-white and often a better buy than pure white: it flatters skin, cloth and organic subjects where true white reads cold.
Zenithal priming: having both
The technique that gets round the whole question. Prime the model black, then spray white lightly from directly above only. The result is a model that is dark underneath and light on top, with a complete pre-shaded gradient already in place.
Paint over that with thinned colors or one-coat paints, and the underlying light-and-dark shows through to give you shading for nothing. It is the single most effective priming technique there is and it needs no extra product, just two cans and one extra pass.
It is easier with an airbrush, where you control the direction precisely, but two aerosols and a careful hand do the job.
Pick this if
- It is your first army and you are unsure: gray.
- Your scheme is dark or metallic, or you want to drybrush: black.
- Your scheme is bright, or you are using Contrast or Speedpaint: white or bone.
- You want shading for free: black then zenithal white.
- You have settled on one army color: a colored primer in that color — see the spray primers.
The picks in full
Citadel Spray: Grey Seer
The light gray primer Contrast paints are formulated for. Also the most forgiving primer color full stop, because it flatters both light and dark schemes.
What it gets right
- The primer Contrast paints were designed against — colors come out as the pot suggests
- Light enough for bright colors, dark enough that shadows are not fighting you
- Shows up mold lines and gaps while you can still fix them
Who it is wrong for
- Aerosol, with the same weather constraints as any spray can
- Neither the deep shadows of black nor the brightness of white; it is a compromise by design
- Priced at Citadel levels for what is, chemically, gray primer

Citadel Spray: Chaos Black
A deep matte black that gives you instant shadows and a hard job on highlights. The right primer if drybrushing is your plan.
What it gets right
- Shadows are done before you start — recesses stay dark on their own
- Drybrushing over black gives dramatic contrast with almost no skill required
- Exactly the primer the official Citadel guides assume for most schemes
Who it is wrong for
- Every light color over black needs multiple coats — yellows and whites are miserable
- Notoriously sensitive to humidity and cold; it goes chalky and grainy outside its window
- Hides your own mold lines and gaps until the basecoat reveals them

The Army Painter Colour Primer spray
A spray primer in army colors rather than just black, white and gray. Prime in your scheme's base color and you have saved an entire painting step.
What it gets right
- Priming in your base color removes a whole step from every model in the army
- 400 ml cans cover a lot of models for the money
- Matt finish gives later paint something to grip
Who it is wrong for
- Aerosol, so it needs dry weather, decent temperature and outdoor space
- Goes grainy fast in humidity or cold — the single most common primer complaint there is
- A colored primer locks you into that scheme; gray keeps your options open

Vallejo Surface Primer
A water-based acrylic primer that brushes or airbrushes on with almost no smell. The answer for anyone who cannot spray outdoors.
What it gets right
- No aerosol, no fumes, no weather window — prime at the kitchen table in February
- Sprays through an airbrush straight from the bottle, needing little or no thinning
- Sold in large bottles, so priming a whole army is cheap
Who it is wrong for
- Brushing it on fills fine detail if you are heavy-handed — it wants thin coats
- Needs a full day to cure hard; handled too early it can peel at contact points
- An airbrush or a lot of patience is really required to get a spray-can-smooth finish
