Art Glossary
A comprehensive glossary of art terms, techniques, movements, and materials. From chiaroscuro to creative coding, find clear definitions for every art concept.
C
Cadmium Colors: The Vibrant Pigments That Revolutionized the 19th Century Palette
Cadmium pigments produce the most vibrant yellows, oranges, and reds in painting. Learn their history from 1818 to today, why they degrade, and how artists from Van Gogh to Pollock used them.
Carbon Black: The Pigment From Fire That Made Painting Possible
Carbon black is the pigment from burnt organic matter, used in cave paintings for 40,000 years. Learn its history, types from charcoal to lamp black, and how artists used it.
Cochineal: The Insect Dye That Colored Empires
Cochineal is a brilliant red dye made from insects that fed Aztec and Spanish empires. Learn its 2,000-year history, how it reached European art, and why it still matters today.
L
Lead White: The Toxic Pigment That Dominated Painting for 2,000 Years
Lead white was the most important white pigment in European painting for two millennia. Learn its history, why it was so valued, and how its toxicity led to its replacement.
Lightfastness: Why Some Pigments Survive Centuries and Others Vanish in Months
Lightfastness measures how well a pigment resists fading under light. Learn how the Blue Wool scale, ASTM ratings, and microfade testing protect art from irreversible color loss.
N
Naples Yellow: The Oldest Synthetic Pigment in Art History (3500 Years)
Naples yellow is lead antimoniate, one of the oldest synthetic pigments known. First used in Egyptian glass around 1500 BCE, it shaped painting from the Renaissance to the 19th century.
Nihonga: Modern Japanese-Style Painting, Mineral Pigments, and the Invention of Tradition
Nihonga is modern Japanese-style painting using mineral pigments and animal glue. Learn about Yokoyama Taikan, Uemura Shoen, and Higashiyama Kaii.
P
Pastel: Pure Pigment Sticks From Leonardo to Degas and Beyond
Pastel is a stick of pure pigment held together with minimal binder. Learn how Degas layered pastels with fixative, how La Tour built portraits in the 18th century, and why pastel blurs drawing and painting.
Pigment: The Colored Substance That Makes Paint Paint
Pigment is the colored substance used in paint, from prehistoric ochre to synthetic cadmiums. Learn its history, chemistry, types, and why some pigments last centuries.
T
Titanium White: The Modern Pigment That Replaced Lead
Titanium white is the most opaque white pigment ever made, replacing lead white in the 20th century. Learn its history, how it changed painting, and why it matters for dating art.
Tooth: The Surface Roughness That Grabs Pigment and Holds It
Tooth is the surface roughness of paper, canvas, or panel that grips pigment. Learn why pastelists, watercolorists, and oil painters depend on tooth for adhesion and layering.
Why an Art Glossary?
Art has always had a language problem. Walk into any gallery and you will hear terms like chiaroscuro, impasto, sfumato, and pentimento thrown around as if everyone knows what they mean. Most people do not. They nod along, afraid to ask, and miss half of what the painting is actually doing.
This glossary exists to fix that. Every entry is written in plain English with real examples: specific paintings, specific artists, specific dates. When we explain plein air, we point you to Monet working beside the Seine in 1873, not a generic definition copied from a dictionary. When we cover creative coding, we start with Casey Reas and Ben Fry at MIT in 2001, not a vague paragraph about "art and technology."
The terms here span centuries and disciplines. You will find Renaissance techniques sitting next to digital art movements, printmaking terminology next to motion graphics concepts. That mix is intentional. Art does not stay in neat historical boxes, and neither does the vocabulary we use to talk about it. A painter working today might need to understand glazing just as much as a 3D animator needs to know what kinetic typography means.
Each definition is a starting point, not a finish line. We write them to be specific enough that you can recognize the technique the next time you see it, but short enough that you can read one in under five minutes. If a term leads you to a painting you had not considered before, or sends you down a rabbit hole about a movement you had never heard of, the glossary is doing its job.
New terms are added regularly. If there is a concept you keep running into but cannot find here, that is a gap we want to fill. The best art terminology does not stay still. It grows as artists invent new ways of working, and the language has to keep up.
