Gouache sits somewhere between watercolor and acrylic: it is water-based and rewettable like watercolor, but opaque enough to paint light over dark like acrylic. That makes it one of the most forgiving paints for a first serious painting, provided you get the consistency right. This gouache painting tutorial for beginners covers the basic supplies, the one mixing skill that matters most, three warm-up exercises and a complete step-by-step landscape you can finish in an afternoon.
Quick answer: To start with gouache, use heavy watercolor or mixed media paper, a few synthetic brushes and a small palette of primaries plus white. Mix paint to a creamy, yogurt-like consistency, paint large background shapes first and work toward smaller, lighter details on top. Let each layer dry, use light strokes so lower layers do not reactivate, and remember that light colors dry darker and dark colors dry lighter.
What Makes Gouache Different
Gouache is pigment bound with gum arabic, like watercolor, but with a higher pigment load and often an added white filler that makes it opaque. Three properties shape how you paint with it:
- Opacity: you can cover mistakes and paint light colors over dark ones.
- Matte, flat finish: dried gouache has a velvety, poster-like surface, ideal for illustration.
- Rewettable: dry gouache can be reactivated with water. That lets you revive dried paint on the palette, but it also means heavy brushing can lift lower layers.
There is also acrylic gouache, which uses an acrylic binder and dries permanent. It does not reactivate, so layering is easier, but you cannot rewet it on the palette. This tutorial focuses on traditional gouache. For more beginner projects in other media, our painting tutorials hub collects technique guides from first strokes to finished pieces.
Beginner Supplies
| Item | What to look for | Why |
|---|---|---|
| Paint | A small set or tubes of warm and cool primaries plus a large white | White gets used the most; mixing teaches color quickly |
| Paper | Watercolor paper around 300gsm (140lb) or heavy mixed media paper | Takes water without buckling badly |
| Brushes | Synthetic flat (about 1/2 inch), medium round, small round or liner | Synthetics are durable and handle opaque paint well |
| Palette | White ceramic plate or plastic palette with wells | Easy to see true colors; ceramic cleans easily |
| Water | Two jars, one for rinsing, one clean | Keeps mixes from getting muddy |
| Extras | Paper towel, masking tape, pencil, spray bottle | Blotting, clean borders, keeping paint moist |
A limited palette of six colors is plenty: a warm and cool yellow, a warm and cool red, a warm and cool blue, plus white. Adding a burnt sienna or raw umber helps with natural tones.
The Most Important Skill: Consistency
Almost every beginner problem with gouache, whether streaks, cracking or chalky patches, comes from paint that is too thin or too thick. Aim for these three consistencies:
- Thin, like milk: for underpainting and transparent washes. Behaves like watercolor.
- Creamy, like yogurt: the main working consistency. Flat, opaque coverage in one coat.
- Thick, like toothpaste: straight from the tube. Use for small highlights only; thick layers can crack when dry.
To reach creamy consistency, squeeze a pea-sized amount onto the palette, add a few drops of water with your brush and mix until it flows smoothly but still covers the paper beneath it. Test on scrap: if you can see the paper texture through it, add a touch more paint; if it drags and leaves ridges, add a drop of water.
Three Warm-Up Exercises
Exercise 1: Flat color swatches
Paint six 1-inch squares, one in each color, at creamy consistency. Aim for flat, streak-free coverage in a single pass. This trains your eye and hand to find the right mix.
Exercise 2: Value scale
Draw a row of five boxes. Paint one end in a dark color such as blue mixed with a little red, the other end in white, and mix three steps between them by adding white gradually. This teaches how gouache shifts value, and how much white you need.
Exercise 3: Dry test
Paint two swatches, a light pink and a dark blue. When dry, compare to the wet mixes on your palette. Light colors usually dry slightly darker and dark colors slightly lighter. Knowing that shift prevents surprises.
Step-by-Step Gouache Painting Tutorial for Beginners: Sunset Mountain Landscape
This simple landscape uses a gradient sky, layered mountains, a lake and a few trees. It teaches background-to-foreground layering, a core gouache skill.
Step 1: Prepare the paper
Tape a piece of paper about 5 by 7 inches to a board on all four sides. Lightly sketch a horizon line about two-thirds down, two or three overlapping mountain ridges above it, and a few vertical tree shapes in the foreground on one side.
Step 2: Paint the sky gradient
Mix three colors at creamy consistency: a pale yellow, a peach (yellow, red and white) and a soft violet (blue, red and white). Starting at the horizon with yellow, paint horizontal strokes upward, switching to peach, then violet near the top. Blend where colors meet by brushing back and forth while both are wet. Work quickly; gouache dries fast on paper.
If a blend dries with a hard edge, wait until it is fully dry, then paint a thin strip of the in-between color across the seam.
Step 3: Paint the farthest mountain
Distant objects look lighter and cooler. Mix the violet with extra white and a touch of blue. Paint the farthest ridge as a flat shape. Let it dry for a few minutes until matte.
Step 4: Paint the middle mountain
Use the same mix with a little less white so it is slightly darker. Paint the second ridge overlapping the first. Because gouache is opaque, you can paint right over the edge of the first mountain without it showing through.
Step 5: Paint the nearest mountain
Darken the mix again with more blue and a touch of red. Paint the closest ridge. You now have three values of mountains, creating depth.
Step 6: Add the lake
Below the horizon, paint the lake with the sky colors in reverse order: violet near the shoreline, peach in the middle and a little yellow reflection. Use horizontal strokes. While dry, add a few thin horizontal lines of lighter color for ripples.
Step 7: Paint the foreground shore and trees
Mix a dark green-blue by combining blue, a little yellow and a touch of red. Paint the shoreline as a dark band, then the trees as tall triangles of short, downward dabs with a round brush. Keep these the darkest values in the painting so they come forward.
Step 8: Add highlights
Once everything is dry, use thicker, pale yellow-white paint with a small brush to add glints on the water, a thin light edge on one side of the mountains where the sunset hits, and maybe a few stars or a small moon. Use light pressure and a single pass so you do not lift the paint below.
Step 9: Remove the tape
Peel the tape away slowly at a low angle, pulling away from the painting, to reveal a clean border.
Gouache Paint Tutorial: Five Brush Techniques to Practice
Once the landscape feels comfortable, these techniques add variety to your paintings. Practice each on a scrap strip before using it in a piece.
- Flat fill: load a flat brush with creamy paint and lay parallel strokes edge to edge without going back over them. The goal is an even, poster-like shape.
- Soft blend: lay two colors side by side while wet, then stroke along the boundary with a damp, clean brush to merge them. Work fast before the paint sets.
- Dry brush: wipe most of the paint off a brush and skim it across dry paint or textured paper. Useful for grass, sparkle on water and weathered wood.
- Glazing with thin gouache: dilute a color to milky consistency and pass it once over a dry area to tint it. Keep it to one stroke to avoid lifting.
- Stippling and dabbing: tap the tip of a round brush to build foliage, texture and soft edges from many small dots.
Combining flat fills for big shapes, blends for skies and dry brush or stippling for texture covers most beginner subjects.
Layering Without Lifting
Because gouache rewets, the main beginner frustration is lower layers mixing into upper ones. These habits help:
- Let each layer dry until matte before painting over it.
- Use slightly thicker paint for upper layers so you need fewer strokes.
- Paint with one confident stroke rather than scrubbing back and forth.
- Keep a soft brush for upper layers; stiff brushes disturb paint below.
- For many layers, consider acrylic gouache for the base layers, then traditional gouache on top.
Common Beginner Mistakes and Fixes
| Problem | Cause | Fix |
|---|---|---|
| Streaky, patchy color | Paint too thin | Mix to creamy consistency, one pass |
| Cracking | Paint too thick | Add a little water, keep thick paint to small areas |
| Muddy colors | Dirty water or overmixing | Two water jars, limit mixes to two or three colors |
| Lower layers lifting | Overbrushing wet on dry | Fewer strokes, let layers dry fully |
| Colors look different dry | Natural value shift of gouache | Test swatches and let them dry first |
| Chalky, dull colors | Too much white in every mix | Keep some mixes pure, use white selectively |
| Paper buckling | Thin paper or too much water | Heavier paper, tape edges |
Gouache Compared With Other Beginner Media
| Medium | Opacity | Fixes mistakes? | Learning curve |
|---|---|---|---|
| Gouache | Opaque | Yes, paint over or rewet | Moderate |
| Watercolor | Transparent | Limited | Steeper control of water |
| Acrylic | Opaque to transparent | Yes, paint over | Moderate; dries fast and permanent |
| Oil | Opaque to transparent | Yes, slow drying | Moderate; longer process and solvents |

Next Projects to Try
- Night sky and galaxy scenes. Gouache’s opacity is perfect for bright stars over dark backgrounds. The approach in our space galaxy painting tutorial adapts well to gouache.
- Simple botanicals. Flat leaves and flowers with light veins painted on top.
- Food illustrations. Bright, flat colors and clean edges suit fruit and pastries.
- Small daily studies. 3 by 3 inch thumbnails of skies or landscapes build speed and color sense.
Caring for Gouache Paints and Paintings
Dried paint on the palette can be rewetted with a spray of water, so you can keep a palette going for several sessions; cover it to keep dust out. Recap tubes tightly so paint does not dry out inside. Finished gouache paintings are water-sensitive and can scuff, so store them flat between sheets of paper and frame them behind glass. Varnishing gouache is possible with spray varnishes made for it, but it can darken colors and change the matte look, so test first.
FAQs
Is gouache good for beginners?
Yes. Its opacity lets you cover mistakes and paint light over dark, and it cleans up with water. The main skill to learn is mixing a creamy consistency.
Do you need water to use gouache?
Yes. Gouache is mixed with a little water to reach a creamy consistency. Straight from the tube it is too thick and can crack.
What paper is best for gouache?
Watercolor paper around 300gsm (140lb) or heavy mixed media paper works well. Thin paper buckles when wet.
Can you layer gouache?
Yes, but lower layers can reactivate. Let each layer dry, use fewer strokes and slightly thicker paint on top.
Why does gouache dry a different color?
Gouache commonly shifts in value as it dries: light colors look a bit darker and dark colors a bit lighter. Test swatches on scrap paper to plan for it.
What is a good first gouache painting?
A simple landscape with a gradient sky and layered mountains is ideal, as it teaches consistency, blending and background-to-foreground layering.
Next Step
This gouache painting tutorial for beginners comes down to three habits: mix to a creamy consistency, paint from background to foreground, and let layers dry before adding light details on top.
