1. Fundamentals of Tone

1.1 What Tone Is in Painting

Tone is the level of lightness or darkness of a color that defines the volume and shape of an object.

In painting, there are three main zones:

• Light — the brightest areas where direct light hits.

• Midtone — the main mass of the form, the area that holds the volume.

• Shadow — the dark part of the form, hidden from direct light.

Main idea: the form relies on the midtone, while light and shadow only emphasize it. Without a midtone, the volume disappears.

1.2 Why the Midtone Is More Important Than Light or Shadow

• The midtone creates a sense of mass. Even if the light is bright and the shadow deep, the form will lose its credibility if the midtone is not established.

• It serves as the framework for the entire image: light and shadow must obey it.

• Working with midtones trains you to see the form as a whole, rather than just copying patches of light and shadow.

Example: When painting a cheek, the midtone shows its turn, the light is just a highlight on the protrusion, and the shadow marks the boundary separating the cheek from the eye or nose.

1.3 Terminology and Its Influence on the Artist’s Thinking

In Russian art schools, the word poluton (half-tone) is often used. It can be misleading:

• The prefix “half” gives the impression of being secondary.

• Students tend to look for “transitions” instead of holding the form.

It is more helpful to think like this:

• Midtone — the main mass of the form.

• Mass and Turn — what you hold and measure while working.

• Value — relative lightness or darkness.

The way you name zones and processes affects how your brush works. Terminology shapes your thinking.

1.4 Hierarchy of Zones: Light, Midtone, Shadow

When constructing a form, it is important to follow the order and priorities:

1. Midtone — the core of the form, the basis of volume.

2. Shadow — enhances volume, separates the form from the background or other objects.

3. Light — emphasizes protruding elements, creates highlights, but does not construct the form.

Tip: Work on the midtone first, then shadow, and add light at the end. This goes against the intuitive habit of “highlight first, everything else later.”

1.5 How to Perceive Midtone in Practice

• Midtone is never uniform — it contains warm and cool areas, subtle reflections, and slight changes in saturation.

• These are not “patches,” but small nuances within the mass of the form.

• The midtone maintains the form regardless of the changes in light or color you add.

Example: When painting a nose: the midtone on the wings is slightly darker, on the bridge slightly lighter, but it is all one cohesive mass.

1.6 Practical Tips for Beginners

• First, block in the form with the midtone, without transitions or light.

• Do not break the midtone into small patches — it should be unified.

• Add transitions and light only after the mass is established.

• Squint at your work — this helps check if the form reads correctly.

• Use a black-and-white filter (if working with color) — the form should be clear even without color.

1.7 Summary

• The midtone is the main support of the form.

• Light and shadow are subordinate to the mass.

• Working with midtones develops correct artistic thinking: first structure, then nuances.

• Use simple terms: mass, midtone, turn, value.

Main idea: first hold the form, then bring it to life with light, shadow, and color. This is the key to convincing painting.
