A value scale is a row of swatches from dark to light. It trains your eye to separate values before you tackle a full subject — and it becomes a ruler you can hold beside your work. In our Hanoi studio we ask beginners to paint or draw a five-value scale in the first weeks of drawing foundations.

Common value scales

Three values — quick notan studies and strong graphic designs
Five values — everyday sketching and most outdoor studies
Nine values — subtle matching when you need smooth transitions

You do not need all three on day one. Start with five values; add nine when you want finer control.

Five-value scale (opaque media)

Works with graphite, charcoal, ink wash, gouache, acrylic, or oil. Use black and white (or your darkest and lightest pencils) on a small panel or sturdy paper — about 15 × 20 cm is enough.

Place a pile of black and a larger pile of white. Mix a middle gray that sits halfway between them — you need far less black than you expect.
Mix dark gray (black + middle) and light gray (middle + white). You now have five piles.
Check that each step looks evenly spaced. If two piles look too close, remix before you paint squares.
Paint five squares in order from dark to light. Label them 1 (dark) through 5 (light) if that helps.

Nine-value scale

From your five piles, mix the halfway point between each adjacent pair until you have nine even steps. Make generous piles before painting the row — running out of a mixed value mid-scale is frustrating and hard to match later.

Tip: paint the scale on the underside of a plastic palette or tape a strip to your drawing board so it stays with you while you work.

Watercolor and wash

For transparent watercolor, build value with layered washes rather than adding white to the paint. Draw nine boxes, pre-mix a large wash, and glaze from the light end toward dark — one fewer square each pass until the last box is your deepest tone. Gouache can follow the opaque steps above.

Even spacing matters

The most common mistake is two middle values that are almost identical while the ends jump too far. Squint at the row: each step should feel like a similar jump. If one gap looks bigger, remix that pair only.

Try it at home

Exercise 1 — Five values in one hour

Create a five-value scale with your usual medium. Photograph it in good light. Compare your steps to a printed grayscale strip or a phone app — note which jump looks uneven.

Exercise 2 — Nine values on your palette

Extend the scale to nine values and keep it on your workspace for a week. Before each drawing session, match one subject area to a swatch on the scale.

Common questions

Pencil only? — Yes. Use 2B through 9B or vary pressure on one soft pencil.
Why not buy a printed scale? — Making one forces you to understand mixing; a store-bought strip is a check, not a substitute.
