Short answer: Contrast and speedpaint are fluid, semi-transparent paints that lay down base colour, shadow, and highlight in a single coat over a light base. In other words, they collapse the three steps you would normally do separately, basecoat, wash, and highlight, into one stroke. Reach for them when you want to paint an army fast, when you are new to the hobby, or when you simply need models on the table.
The category landed in 2019 with Citadel Contrast and kicked off a real speed revolution. In the years since, the shelves have filled with rivals: Army Painter Speedpaint, Vallejo Xpress Color, Green Stuff World Dipping Ink, Scale75 Instant Color, and AK Quick Gen all run on the same idea. According to Stahly's continually updated comparison at Tale of Painters, there are now hundreds of one-coat colours on the market. In this guide we break down how these paints work, what base they need, and the mistakes people make most.
What are Contrast and speedpaint, and what are they for?
The names differ, but they all fall into one category: these are one-coat paint systems. They carry a heavy pigment load and a special medium (the carrier fluid that does the work). Brush them generously over a light base, and colour, shadow, and highlight all show up at once.
The easiest way to picture this is to recall the classic method. Normally you lay a flat basecoat, then add a wash to darken the recesses, and finally add a highlight to the raised edges. These paints handle all three layers in a single pass. That is exactly why they suit big armies, swarms of rank-and-file, and any model that only needs a solid tabletop standard.
As a technique it sits somewhere between beginner and intermediate, so it is nothing to be scared of. On the speed side things get really interesting, because this is one of the fastest known ways to paint an army. If you want to finish a crowded unit in a single evening, this is exactly the tool you need; the same job in the classic three-layer method would take you several times longer.
How does it work?
The whole trick is hidden in the medium, because it lowers surface tension. As a result, the paint slides off the model's raised areas and pools into the recesses. Leave it over a light or zenithal base and the physics starts doing the work for you:
- On raised surfaces the paint stays thin, the light base shows through, and you get a natural highlight.
- In the recesses the paint collects and darkens, so a shadow forms on its own.
- In the transition zones a mid-tone settles in between.
The result is a volumetric, shaded, lit surface in a single coat. The golden rule here is simple: the better you prep the base, the better the result. That is precisely why these paints pair perfectly with Zenithal Priming and Slapchop. Both hand the paint a ready-made bright-to-dark base to work over.
How do you do it, step by step?
The good news is that one-coat systems are only a few minutes of work in practice. Even so, order matters, because without a light base these paints will not behave the way you want.
- Prep the base: Lay a light or white primer; ideally build a zenithal or slapchop base. A dark base kills the effect entirely.
- Apply one coat: Brush the paint on generously, but without flooding it into a puddle, and let it flow into the recesses.
- Manage the excess: If paint pools on a raised area, wick it away with a clean, damp brush. Otherwise it dries into a stain and a glossy bead.
- Let it dry: The transparent layer builds its own shadow and highlight; all you have to do is wait.
- Optional accent: Once it is dry, add a couple of edge highlights or a second thin coat to push the depth further.
Which paint, which brand, which brush?
They all work on the one-coat principle, yet every brand has its own character, and their finish and behaviour differ. The notes below should help you decide:
- Citadel Contrast: Top of Stahly's tier list; richly pigmented, saturated, with a wide range. Some colours dry glossy.
- Army Painter Speedpaint 2.0: A favourite over zenithal and slapchop bases; broad range. The reactivation issue (paint lifting when re-wetted) is also much reduced versus the first generation.
- Vallejo Xpress Color: Gives a matt finish and rarely reactivates, which makes layering on top easy.
- Green Stuff World Dipping Ink, Scale75 Instant Color, AK Quick Gen: Alternative ranges that stand out with different saturation and finish traits.
When it comes to brushes, a wide synthetic or blend that holds plenty of paint does the job nicely. That said, these paints run very wet and can wear out pricey natural tips, so it is smart to dedicate a workhorse brush to the task. Keep a separate clean, dry brush handy too, for wicking up excess. And on big armour panels or wide areas like a cloak, a wide brush that spreads the paint in one pass speeds things up considerably.
The sweet spot really comes down to one simple rule: a zenithal or slapchop base plus contrast is where speed meets quality. And when you want to see which colour looks best in which brand, Stahly's comparison chart at Tale of Painters is the most reliable source you have.
The most common mistakes
These paints are forgiving overall, but a few classic traps still catch people again and again. Most of them come down to the base and to managing excess:
- Using a dark or black base: The transparent paint loses its effect entirely. A light base is non-negotiable.
- Not fixing pooling: Paint collected on a raised area dries into a stain and a shiny ring.
- Adding no accents at all: One coat is enough on most models, but one or two edge highlights make a huge difference on some pieces.
- Overlooking the finish difference: A glossy contrast sitting next to a matt xpress in the same scene can throw unexpected shine.
Pro tips
Beyond the basics, a few small habits push the result toward gallery level. All of them are simple, field-tested moves:
- If you run into reactivation trouble (the underlayer lifting when re-wetted), either switch to Vallejo Xpress or add a matt varnish layer in between.
- Mix brands freely, because each one's strongest colours differ, like Citadel's reds and Speedpaint's golds.
- Thin the paint with its own medium or contrast medium and use it for Glazing too; it is great for subtle transitions.
- The same transparent logic is a cousin of Washing, Shading & Pin Wash; it pays to learn to use them together.
- For batch work, fold this system into the One-Coat Techniques approach; you can finish a whole unit in one sitting.
Frequently Asked Questions
Can contrast paint replace normal paint?
In most cases yes, but it really depends on your goal. For armies, rank-and-file, and quick tabletop models, it is more than enough on its own. For a competition-grade centrepiece, you would use contrast as a base and add layering and edge highlights on top. So they are not rivals; they actually complement each other.
What base does contrast need?
The one requirement here is a light base: white, light grey, or a bone-tone primer. The best results come from a zenithal prime (white sprayed from above) or a slapchop (black-and-white drybrush) base. With a dark or black primer, the transparent paint cannot produce any shadow-and-highlight effect.
What is the difference between Speedpaint and Contrast?
Both work on the same one-coat principle; the difference is in the details. Citadel Contrast is saturated, pigment-rich, and broad in range, and some colours dry glossy. Army Painter Speedpaint 2.0 is zenithal- and slapchop-friendly, wide in colour, and has reduced reactivation. That is why most painters keep both and pick by colour.
Is one coat really enough?
For a standard tabletop model it usually is, because the paint delivers colour, shadow, and highlight in a single pass. Still, on some pieces, adding one or two edge highlights or a second thin coat after it dries noticeably increases depth. That optional step is where a spent minute pays back the most.
Why is my contrast paint staining?
Usually for one of two reasons: either you did not wick away the excess pooled on a raised area in time, or you applied so much that it puddled. The fix is simple; wick the pooling spots with a clean damp brush right after applying. A very dark base also disrupts smooth flow and causes uneven staining, so watch out for that too.
Can I mix brands?
Absolutely. You can comfortably use Citadel, Speedpaint, and Xpress together on the same model. Each brand's brightest colours differ, so painters often cherry-pick the best tones and work from a mixed palette. The one thing to watch is the finish difference: gloss versus matt can show on the same surface, so balance it with varnish if needed.
Key takeaway
The one thing to remember is this: contrast and speedpaint give you shadow and highlight in a single coat over a light base, so the base is what makes the result. Pair them with a zenithal or slapchop foundation, manage the excess, add a small edge highlight to a few pieces, and you will finish your army in minutes rather than hours.
