How to Paint Alla Prima

Alla prima means finishing a painting in a single wet sitting, before any of it dries. The Italian translates to "at first attempt." You mix the right color, put it in the right place at the right value, and you leave it. No glazing, no second layer to rescue the first. The whole method lives or dies on one skill. Get the note right the first time, then have the nerve to stop touching it.

Everything below is how to give yourself the best odds of that.

What alla prima actually demands

Alla prima asks for decisiveness before it asks for skill. The paint stays wet and you finish in one pass, so every stroke has to be close to right when it lands, and fiddling only drags the surface toward grey.

You will also hear it called wet-on-wet, direct painting, or premier coup, the first blow. They all point at the same thing. Wet paint goes into wet paint, the colors marry on the canvas instead of in layers, and the clock is running because nothing underneath is drying to protect itself. The Impressionists ran with it because it caught fast light. Sargent and Sorolla built whole careers on it.

The enemy is overworking, and it is the easy mistake. Wet color plus wet color plus one more wet correction becomes soup. The painters who are good at this are good at restraint, not speed. In my own direct passages, you paint better when you are not overthinking it. There is a way of working I call swagger, painting from complete confidence. Alla prima is swagger with a deadline.

Set up so the method has a chance

Most alla prima problems are setup problems. Get the surface, the palette, and the brushes sorted before you start, and the painting gets twice as easy.

Start with a toned ground. A mid-tone wash, swept on and ragged smooth until it is slick, gives you a surface paint glides across and a value you can read both light and dark against. Premix your main notes before you touch the canvas, because stopping to hunt for a color mid-stroke is how momentum dies. Use bigger brushes than feel comfortable, since a big brush forces you to state a shape instead of niggling at it. Keep a little medium on hand for flow, and keep a palette knife or the blunt end of a brush within reach. Taking paint away by scraping back to the ground is as much a move as putting it down. Some of the best marks in a direct painting are the ones you lifted out, not the ones you laid in.

How to paint a subject alla prima, step by step

Locate first, mass the big shapes, then place each note at its final color and value and leave it alone. That order is most of the technique.

Begin by locating everything before you render anything. I work this way on any start, location first, then form and nuance. If the shapes sit in the right place, you can resolve them later in the same sitting. If they sit in the wrong place, a beautiful eyelash will not save the head. Mass the big shadow and light shapes early and a little aggressively. The more you lay in during the first hour, the more you enjoy the rest, because the painting is already standing up and you are adjusting rather than building from nothing.

Then comes the part that takes nerve. Mix a note, check it against its neighbor for hue and value, put it down once, and move on. Resist the small detail that calls to you early. Fixate on one eye too soon and you stall, and the rest of the head stays a flat shape while you polish a corner. Keep cycling. Observe, analyze, make a decision, make the change, then go back to looking. Every stroke changes the painting, so the read has to stay fresh. If a passage is almost right, leave it almost right. Coming in to drastically fix something that was nearly there is how good starts die.

The limited palette that keeps color clean

A limited palette is the biggest single reason an alla prima painting stays clean instead of sliding to grey. Fewer pigments means fewer chances to mix mud, and forcing every color through the same few tubes pulls the whole picture into harmony on its own.

The classic example is the Zorn palette, named for Anders Zorn. It is white, yellow ochre, a warm red (vermilion or cadmium red light), and ivory black. Four tubes. The trick that surprises people is the black. Ivory black leans cool, so against the warm reds and ochres it stands in for blue well enough to mix convincing greens and cool greys. A painter working that palette cannot make a garish mistake, because the palette has no garish color in it. Constraint is doing the work. You can swap in your own four, but keep it small. Every pigment you add is another way to go wrong. See how a direct painter handled this on the pages for Sargent, Zorn, and Sorolla.

When alla prima beats layering, and when it does not

Use alla prima when freshness and light matter more than fine detail, and reach for layers when you need built depth, transparent glazes, or room to correct over days. It depends on the painting you are trying to make.

The honest framing is that these answer different questions. Direct painting asks you to commit in the moment. A layered approach, like a grisaille underpainting, asks you to plan and wait. Neither is more serious than the other. In fact most layered painters use alla prima thinking inside a passage, putting a careful first pass down wet and leaving it because they want that freshness to survive into the finish. I plan some paintings like a military campaign, ten layers in places, and yet in the areas that need to stay alive I treat the first pass as if it were the only pass. Knowing which kind of painting is in front of you, and which kind of painter you are, is the longer project. That is the subject of how to develop your own painting style.

Is alla prima easy? No, period. It hides nothing and forgives little. But the skill it builds, deciding and committing, is the skill under all painting. If that trade is worth it to you, start.

If you are not sure whether you are a layer-and-plan painter or a commit-in-the-moment painter, the Artist Reading is built to find out. The workshop that teaches direct painting as a way of thinking, not a set of tricks, opens enrollment soon. You can join the waitlist.

Most alla prima paintings are lost in the last ten minutes, not the first. Learn when to put the brush down.

FAQ

What palette did Anders Zorn use? The Zorn palette is white, yellow ochre, a warm red (vermilion, often substituted today with cadmium red light), and ivory black. Four pigments. The ivory black runs cool, so it doubles as a near-blue for mixing greens and cool greys, which is why the limited set still covers a full head.

How do you keep alla prima colors from going muddy? Limit the palette, premix your main notes before you start, use bigger brushes, and touch each passage fewer times. Mud comes from over-mixing wet into wet. When a color is right, set it down and walk away from it. Scraping a passage back to the ground beats blending it to death.

Can a beginner start with alla prima? Yes, and small studies are the place to do it. Alla prima teaches decisiveness faster than any other method, because the wet paint punishes hesitation. It is hard and it is honest, which makes it a good teacher. Keep the early ones small so a failed study costs an afternoon, not a week.

How long does an alla prima painting take? One sitting, usually a few hours, defined by finishing while the paint is still wet rather than by the clock. A large piece pushes the limit, since the first passages start setting up before you reach the last. That window is the real constraint, not the size of the canvas.
