Positive and Negative Space Cat Drawing: Figure-Ground Contrast Exercise

Object Drawing Lessons

This exercise focuses on one narrow skill: making a cat read clearly as positive space by controlling the negative space around it. You will draw a simple cat silhouette, then shade the surround so the cat remains the figure and the background becomes a deliberate, contrasting field. The goal is not a detailed cat portrait but a clear figure-ground relationship. Work on paper with a pencil and one shading tool. Keep the cat shape simple and closed, then treat the surround as a single shape that you block in stages. All numerical values below are hypothetical examples for practice, not manufacturing standards.

Set up the plate and define the cat silhouette

Begin with a rectangular panel. Lightly mark a margin so the surround has a boundary. Draw the cat as a closed silhouette: head, ears, body, tail, and legs connected without gaps. Avoid interior details at this stage; the silhouette must read as one shape. A simple standing cat with a curved tail is enough.

Check the silhouette by turning the paper upside down or viewing it from a distance. If the cat shape still reads as a single closed form, it is ready. If parts merge into the surround, redraw those edges more clearly before shading.

1. Draw a light rectangular border on your paper.
2. Sketch a closed cat silhouette inside the border, leaving at least two finger-widths of surround on all sides.
3. Erase any interior lines that do not help the outer shape read.
4. Confirm the silhouette is closed and simple before adding shade.

Block the negative-space surround in stages

Treat the surround as one continuous shape with the cat removed. Block it in three passes: first outline the outer border and the cat edge, then shade a narrow band next to the cat, then fill outward to the border. Keep the shading direction consistent, such as diagonal strokes, so the surround reads as a field rather than a collection of separate patches.

Leave a small unshaded gap between the cat edge and the shaded surround if you want a crisp separation, or shade right up to the cat edge for maximum contrast. Either convention is valid if applied consistently. The cat itself remains unshaded positive space.

1. Outline the outer border and the cat edge lightly.
2. Shade a band about one centimeter wide around the cat, following its contour.
3. Continue shading outward to the border in the same stroke direction.
4. Darken any light patches in the surround so the field is even.
5. Check that no shade crosses into the cat silhouette.

Judge contrast and adjust

View the drawing from about two meters away. The cat should stand out immediately as the lighter figure against the darker surround. If the cat and surround look similar in value, darken the surround or lighten the cat by erasing stray marks. If the surround looks patchy, unify it with additional strokes in the same direction.

A valid result may use a light cat on a dark surround or a dark cat on a light surround, provided the figure-ground contrast is clear and the convention is stated. The rubric below accepts either convention.

1. Step back and squint at the drawing to compare values.
2. Darken the surround where it is too light or patchy.
3. Erase any shade that entered the cat silhouette.
4. Confirm the cat reads as one closed shape against a continuous field.

Worked example

A student draws a closed cat silhouette on a 15 cm by 20 cm panel and shades the surround with diagonal strokes, leaving a 1 cm unshaded gap around the cat. From two meters away the cat reads clearly. Is this a valid result?

Four practice exercises

Common mistakes

• Shading inside the cat silhouette, which destroys the positive-space reading. Keep the cat unshaded and reserve all shading for the surround. Erase any marks inside the cat edge.
• Leaving gaps between the cat edge and the surround so the cat does not read as a closed figure. Shade right up to the cat edge or leave a deliberate, even gap applied consistently around the whole silhouette.
• Making the surround patchy with inconsistent stroke directions. Use one stroke direction and overlap strokes to build an even field.
• Drawing a cat silhouette with interior details that compete with the figure-ground contrast. Simplify to a closed outer shape and omit interior lines until the contrast is clear.

Self-check rubric

• Cat silhouette is closed and reads as a single positive shape.
• Surround is shaded as a continuous negative-space field.
• Figure-ground contrast is clear from a distance of about two meters.
• Shading convention (gap or no gap, light or dark cat) is applied consistently.
• No shading crosses into the cat silhouette.
• Valid alternatives are accepted: light cat on dark surround or dark cat on light surround.
