Advanced Paint by Numbers Techniques: Blending, Shading and Making It Your Own

Quick answer: Once you have finished a few canvases, five techniques lift a paint by numbers from neat to genuinely painterly: blending the edge between two neighboring sections while both are wet, adding a touch of the darker neighbor into shadows and the lighter one into highlights, varying your brush direction to follow the form, building texture with thicker paint in the foreground, and adding one or two details of your own — a catchlight in an eye, a warmer sky at the horizon. None of them requires drawing skill. All of them are reversible: if you do not like it, let it dry and paint the number back over it.

The numbers get you a good painting. They do not get you a painting that looks like a person made decisions, because the person who made them was the designer. This guide is about the small, safe liberties that make a finished canvas look like yours — and about the order to try them in, so nothing goes wrong that cannot be fixed.

When you are ready for this

After two or three canvases, when the edges are clean without thinking and you find yourself looking at a finished section and wishing it had a little more life. Not before: these techniques depend on being comfortable with the basics, and a first canvas is better finished plainly. If you are still fighting the lines, our troubleshooting guide is the one to read first.

Practice each technique on a mini canvas or in an unimportant corner of the background before you try it on the face of a portrait.

1. Blending the edges

The hard line between two sections is what makes a finished canvas look like a kit. Softening a few of those lines — not all — is the single most effective thing you can do.

Paint two neighboring sections, one after the other, while both are still wet. Then, with a clean, slightly damp brush, stroke gently along the line between them, once or twice, in the direction of the line. The two colors feather into each other over a millimeter or two. Wipe the brush and stop. Overworking turns the blend to mud.

Where to do it: skies (between bands of blue), skin (between a mid-tone and a shadow), water, petals, fur. Where not to: anywhere a crisp edge is the point — the edge of a building against sky, the outline of a vase, a horizon.

Acrylic dries in minutes, so work in small pairs of sections. If it has dried before you get to the line, you can still soften it: mix a tiny amount of the two colors on a palette and paint that mid-shade along the line in one thin stroke.

2. Shading and highlighting with the neighbors

Every section in a design has a darker neighbor and a lighter one. You can use them.

Paint a section its proper color. Then, before it dries, pick up a very small amount of the darker neighboring color on the tip of the brush and touch it into the side of the section that faces away from the light — the underside of a petal, the far side of a cheek. Do the same with the lighter neighbor on the side facing the light. Blend the touch in with a clean damp brush.

The section now has a gentle turn in it instead of being flat. Do this on the main subject only: a face, the nearest flowers, the animal. Leave backgrounds flat so the subject comes forward.

The colors are already in your kit, already matched to the design, and already on the palette. That is why this works without any color mixing.

3. Brush direction that follows the form

Most people paint every section with the same back-and-forth stroke. Painters do not. Strokes that follow the shape of the thing — curving around a petal, radiating from the center of a flower, sweeping across a sky, running along the grain of wood or the fall of hair — make the surface describe the object even in flat color.

This costs nothing and changes a great deal. Look at each section before you paint it and ask which way the thing it belongs to is going. Then paint that way. On a Van Gogh design in particular, follow the direction of his strokes and the result is startling — see our Van Gogh guide.

4. Texture: thick paint where it matters

Acrylic can be applied thickly enough to hold the shape of the brush. A little texture in the foreground and none in the background creates depth, because the eye reads thick paint as close.

Use the paint straight from the pot with no water, on a stiff brush, and dab or drag rather than smooth. Try it on: the nearest flowers in a bouquet, foreground grass, tree bark, waves at the front of a seascape, the highlights on fruit. Keep skies and distant hills smooth.

A caution: thick paint takes longer to dry and is harder to paint over. Do it last, once everything around it is finished.

5. Adding your own details

A few tiny additions read as confidence. Each one takes a minute.

• A catchlight. One small dot of the lightest color in the kit on each eye of a person or animal, at the same position on both. Nothing brings a portrait to life faster.
• A warmer horizon. A thin band of the warmest light color you have, blended into the sky just above the horizon line.
• Highlights on water. A few short, horizontal flicks of near-white where the light would hit.
• Depth in foliage. A few strokes of the darkest green deep between the leaves at the back, and a few of the lightest at the front.
• A signature. Small, in a corner, in a color from the kit. It is your painting.

Rule of thumb: add fewer than you think. Two or three details on a canvas are a touch. Ten are clutter.

6. Changing a color on purpose

You are allowed to disagree with the design. The most common and most successful change is the background: a busy patterned background painted in one calm shade, or a plain background darkened to make the subject glow. The second most common is warming or cooling a sky.

Two rules keep this safe. Change one thing, not several, or the balance the designer built will collapse. And test the new color on a scrap of paper held against the canvas before you commit — a color that looks right in the pot often looks different beside the ones already painted.

The safety net: how to undo anything

Everything above is reversible, which is what makes it worth trying. Acrylic is opaque and dries in minutes. If a blend has gone muddy, a highlight is in the wrong place, or a changed color was a mistake: wait fifteen minutes, then paint the original number back over it in one or two coats. The canvas does not remember.

Keep a little of every color for this reason. Do not empty the pots on the first pass, and if one runs low, reorder it by number before you start the finishing touches.

When you are happy, seal the canvas. A gloss varnish makes blended and textured areas look especially rich.

Frequently asked questions

Can you blend colors in paint by numbers?

Yes. Paint two neighboring sections while both are wet, then stroke gently along the line between them with a clean damp brush. Work in small pairs of sections because acrylic dries fast, and stop after one or two strokes.

How do I make paint by numbers look more realistic?

Soften a few edges by blending, shade the main subject with its darker and lighter neighboring colors, follow the form with your brush direction, and add a catchlight to any eyes. Leave the background flat so the subject comes forward.

Do I need extra paints for these techniques?

No. Every technique here uses the colors already in the kit, which are matched to the design. Keep a little of each color back for finishing touches.

What if I ruin a section?

Let it dry for fifteen minutes and paint the original number back over it. Acrylic is opaque and completely forgiving.

Should I varnish a textured painting?

Yes, once it is fully dry — allow extra time for thick areas. Gloss varnish suits texture and blending best.

Which designs suit these techniques?

Portraits, florals and landscapes with soft edges: Monet and Van Gogh designs, bouquets, skies and water. Hard-edged designs like buildings and pop art are better left crisp.

Make the next one yours

Choose a design with soft edges and room to play — something from the Monet collection, a bouquet from flowers, or a portrait from people and portraits — and try one technique per canvas. A good brush helps here more than anywhere; our brush guide explains which. And when it is done and sealed, sign it.
