Learn the basics of negative painting by creating a forest of trees and build depth with layers of glazing. Add a little salt for texture. The image below is from a class demo I did and has become one of my most popular pins on Pinterest, inspiring the following tutorial.

Some students find negative painting tricky because we are used to seeing and painting objects instead of the spaces around them. Practice with this basic tutorial to understand the concept and soon it will be easy to flip back and forth between observing positive and negative shapes. It’s a useful tool for improving accuracy in drawing and can be integrated into paintings to varying degrees. We’ll start with this simplified design so you can focus on the process without too many confusing little overlapping shapes. Then I’ll provide additional suggestions and examples so you can see the potential and challenge yourself with your own ideas!

Supplies:
140 lb (300 gsm) watercolor paper
3 colors of transparent watercolor paint. In the example below I used permanent rose, sap green and burnt sienna. (The sienna could be substituted with quinacridone gold or gamboge.)
2b pencil and kneaded eraser
Low tack tape (masking, painter’s or artist’s tape)
Board (hardboard panel, gator board, or Coroplast sheet)
Round brushes and a flat for the first wash
Salt
Hair dryer (optional)

Step by Step
Step 1: Random Variegated Wash
Tape your watercolor paper to a hardboard panel with masking tape to ease the buckling from this wet technique and to preserve a neat border. I used a 6″ square. Mix up 3 puddles of paint with a 3/4″ flat brush. The paint should be a thin consistency, similar to coffee. The goal is to create a light random wash over the whole paper, maintaining areas of pure color.
Using a flat brush, wet the whole paper with clean water to help the colors mingle and maintain soft edges, then add some of each pure color, staying mostly warm. Try to create small, medium and large areas of each color. For this step, I find using a flat brush helps to create irregular shapes. Try to avoid ending up with a layer of similarly sized polka dots. If you do use a large round, move the brush around randomly rather than dabbing repeatedly. Allow the colors to touch and mingle but try to keep them pretty pure at this stage. If the paint is wet enough, you can tilt your board to encourage movement. Spatter some of the colors on top for some smaller patterns.
While the paint is still wet with a glossy sheen but no puddles, sprinkle on some salt and leave it to dry. As it dries, the salt will create some additional random textures.

Once completely dry, brush off the salt.
Step 2: Draw a Tree Shape and Paint the Negative Space
Since these are whimsical trees in an imaginary landscape of distorted shapes and wonky lines, freehand drawing works nicely. Drawing one layer at a time, on top of dry paint, allows for easier erasing and the opportunity to preserve appealing areas of texture and color passages. Before drawing, I rotated my paper and decided on the orientation I liked best, considering the random results that were achieved in the first layer and where I wanted to place the first tree.

Draw the first tree including the branches, canopy, and ground it stands on. Consider this as one large shape that will be preserved as the foreground. The negative space/shape is the rest of the area around the tree including the spaces between branches. Paint only this negative space with the second layer of coffee-strength transparent paint. This is called glazing and can serve to unify a layer with common color. Each layer creates a value difference with the previous layer that defines the objects and builds depth. Unique areas of optically mixed color result from transparent layers overlapping previously painted layers.
Prepare puddles of color so you can complete each section in a continuous, even manner. A gentle touch, soft brush and single pass is essential to prevent disturbing previous layers that will become re-activated with water. I used a round brush that allowed me to work quickly on this small format (#10). Since warm colors visually advance and cool, de-saturated colors recede, the colors used are the original colors pre-mixed into secondary and tertiary, less pure colors. Pre-mix a puddle of rose with burnt sienna for an orange. Mix a small amount of rose into a puddle of green. Mix a second green with a small amount of the orange or burnt sienna. As you paint, switch from one puddle to another to vary the color. There’s no need to clean the brush when switching between these mixtures.

Let dry or use a hair dryer to speed things up.
Step 3: Draw Another Tree and Paint the Remaining Negative Space
Here I’ve drawn a second, smaller tree and hill shape that will become the middle ground in the painting. Using a toned-down green, I’ve started to paint the remaining negative spaces that now consist of everything except both tree shapes. I will vary the color but not the value as I go, getting cooler in this layer, with less of the orange.

The negative space gets progressively smaller in each layer so I switched to smaller round brushes (#6, #8). Mix the paint as in the previous step. Staying transparent will build depth while achieving darker values and giving a sense of shade in the woods.
Step 4: Draw the Third Tree and Paint the Last Layer
With the middle ground defined, draw a third tree and hill that will become the background once defined by painting the negative space that remains.


Mix up more paint, eliminating the orange. Using a variety of greens mixed as before, paint all but the three tree shapes.

Let dry.
Step 5: Final Touches
Depending on your results, you may or may not want to make adjustments. After my painting dried, I decided the last layer wasn’t dark enough to differentiate the third tree and create a sense of deep, dark space. So, I glazed over it with a final layer of dark green. Notice how the cooler, more neutralized layers enhance the first tree, making it seem more colorful and warm than before.

After it dries, you can use a kneaded eraser to remove visible pencil marks. Peel the tape off carefully, pulling away from the image to reveal a tidy edge and professional looking painting. Sign it!

Tip:
- Staining and transparent pigments tend not to lift as easily so are well suited to practicing glazing.
A friendly reminder: This tutorial is provided for your personal education only. The line art design, tutorial instructions and photos may not be reproduced for commercial purposes. Your painting may not be entered as original work into shows or contests unless it is your own unique design and not a tracing of mine.
Further suggestions:
- Once you’ve got the process straight, try it with a more complicated subject. You can have several trees, shrubs, grasses or animal silhouettes on each layer, work on a larger format, add more layers and experiment with different colors to achieve different moods or seasons. Try adding details within the shapes.
- Try using negative painting selectively within other paintings. For example, add a new shape on an existing layer of background color, such as a leaf in a floral bouquet or a bottle in a still life, by painting around it in just that local area. While the paint is still wet, soften the outer edge with a damp brush or feather it out with clean water to blend it in to the background, rather than painting the whole background in a uniform layer as we did in the tutorial. You can use the technique to visually separate overlapping objects or strategically emphasize an edge for compositional purposes. See a variety of examples below.
