Paint a 9-step value scale from black to white. Develops the eye's ability to judge and mix discrete value steps — the foundation for everything in value painting.
Painters cannot place values accurately until they can see and mix them at will. This exercise is a sight-training and mixing-training drill: the painter forces themselves to produce 9 discrete tonal steps from black to white, learn to judge whether each step is distinct from its neighbors, and develop the muscle memory for accurate value mixing. The variations push the discipline further — the same scale in a single hue forces value judgment across chroma, and the cross-hue scale at one value level teaches that two colors of different hues can have the same value, which is one of the harder lessons in color perception.
A panel or canvas board, primed and toned mid-gray (50% value). An opaque medium: oils with white and a dark pigment, acrylics, or gouache. A palette with white and your darkest dark (ivory black, mars black, or a deep mixed dark). A medium brush — large enough to fill a 1-inch rectangle, small enough to control. Good light, neutral wall behind your work for honest comparison.
Oils, acrylics, or gouache (any opaque medium); brushes; panel or canvas; palette knife (optional).
1. On the palette, mix pure white and pure black in incremental steps. Start with five steps (white, light gray, mid-gray, dark gray, black) and expand to nine if confident. 2. Paint nine equal rectangles on the panel, in a single row, from darkest on one end to lightest on the other. 3. Step back six feet and view. Can you see clear separation between each step? Or do some steps blend into each other? 4. Adjust mixtures and repaint until you can clearly distinguish nine discrete values at viewing distance. 5. Repeat using a single hue: paint a 9-step value scale of burnt umber + white, or ultramarine + white. Notice how the hue affects perceived value — saturated colors at the same mixture ratio can read at different value steps. 6. Advanced: paint a 9-step scale of two complementary colors at the same value level. Mix the colors so they share the same step on the value scale despite being opposite hues. Verify with a black-and-white photograph.
- Beginner: 5-step scale (white, light gray, mid-gray, dark gray, black). Builds the basic eye. - Standard: 9-step scale, fully graduated, discrete steps. The classic value scale exercise. - Advanced: 5-step scale at three keys — high-key (values 7–11 on an 11-step scale), mid-key (4–8), low-key (1–5). Trains the eye for paintings in different keys. - Cross-hue scale: two complementary colors mixed to share the same value step. Trains value perception independent of hue.
A clean 9-step gradation from black to white where each step is distinct at viewing distance, the mid-gray reads as actually middle, and (in the cross-hue variation) two complementary colors photograph as the same gray.
- Each step distinct from its neighbor at viewing distance (six feet). - Even gradation, no jumps or repeats. - The middle gray reads as actually middle — confirm with a 50% gray paint chip from a hardware store. - On the cross-hue variation: the two colors photograph as the same gray in black and white.
- Working too small — small scales are easier to fudge and harder to verify. - Not stepping back — judging values from arm's length. - Mixing on the fly — for this exercise, pre-mix on the palette in distinct piles. - Forgetting that warm and cool colors of the same value read differently in chroma. - Treating this as a one-time exercise — value perception decays without practice. Repeat the exercise periodically. - Using a pre-printed value scale instead of mixing your own. The mixing is half the lesson.
