Praxis Art key terms

A continuous mark made on a surface by a moving point. Lines vary in length, width, direction, and curvature, and artists use them to define edges, suggest movement, create texture, and guide the viewer's eye.

A flat, enclosed area defined by an edge or outline, existing in two dimensions. Shapes may be geometric, built from regular mathematical forms like circles and squares, or organic, with irregular free-flowing edges.

A three-dimensional object or the illusion of three dimensions on a flat surface. Form has height, width, and depth, and includes volume and mass; sculptors work with actual form while painters suggest it through shading and perspective.

The relative lightness or darkness of a color or tone, ranging from white to black. Value creates contrast, models three-dimensional form, and establishes mood; artists build it with shading, hatching, or by mixing tints and shades.

The surface quality of an artwork, either actual (the physical feel of the material) or implied (the illusion of how a surface might feel). Texture can be rough, smooth, glossy, or matte.

The visual property produced when light of different wavelengths reflects off surfaces and is interpreted by the eye. In art, color has three main attributes-hue, value, and intensity-and can be mixed, layered, or juxtaposed for effect.

The name of a color family on the color wheel, such as red, blue, or yellow-green, independent of how light, dark, bright, or dull it is. Hue distinguishes one color from another.

The brightness or dullness of a color, also called saturation. A pure hue is highly intense; mixing in gray, black, white, or its complement reduces intensity, making the color appear muted or earthy.

Pairs of colors positioned opposite each other on the color wheel, such as red and green or blue and orange. Placed side by side they create strong contrast; mixed together they neutralize each other toward gray or brown.

The distribution of visual weight in a composition. Balance may be symmetrical (mirror-like), asymmetrical (different but equally weighted elements), or radial (arranged around a central point), and it affects how stable an image feels.

The use of contrast, placement, size, or detail to make one area or element draw attention first. Emphasis establishes a focal point and tells the viewer where to look within a composition.

The difference between adjacent elements, such as light versus dark, rough versus smooth, or large versus small. Strong contrast creates visual excitement and clarity; low contrast produces subtlety and soft transitions.

A principle of design that creates a sense of movement or beat through repeated elements, such as shapes, lines, or colors, often with variation in spacing or size. Rhythm guides the eye and unifies a composition.

The empty or open area around and between the subjects of a composition, as opposed to the positive space occupied by objects. Artists use negative space to define shapes, create balance, and add visual interest.

A system for creating the illusion of depth on a flat surface using converging lines that meet at a vanishing point on a horizon line. Objects appear smaller as they recede, mimicking how the eye sees space.

A painting technique in which thick layers of paint are applied so that brush or palette-knife marks stand out from the surface. Impasto creates actual texture and catches light, adding expressive weight to the image.

A technique of dragging a thin, semi-opaque layer of paint over a dried lower layer so the underlying color shows through in broken patches. It softens edges and creates hazy, atmospheric effects.

A thin, transparent layer of diluted paint or ink spread over a surface. Washes are common in watercolor and ink work, where they create even tones, soft gradients, and luminous overlapping layers.

An artwork made by gluing paper, fabric, photographs, or other flat materials onto a support. Collage often juxtaposes unrelated images and textures, and it was central to modern movements such as Cubism.

A three-dimensional artwork constructed from found objects and mixed materials rather than carved or modeled from a single substance. Assemblage is related to collage but occupies real space, often combining wood, metal, and discarded items.

A printmaking process in which the raised areas of a block carry ink and the recessed areas stay blank. Woodcut and linocut are common relief methods, printed by pressing paper onto the inked surface.

A printmaking family in which lines or areas are cut into a metal plate, filled with ink, and wiped so only the incised marks print. Etching, engraving, drypoint, and aquatint are intaglio techniques.

A planographic printmaking process based on the repulsion of oil and water. The artist draws on a limestone or metal plate with a greasy medium, and ink adheres only to the drawn areas before printing.

Also called screen printing, a stencil process in which ink is pushed through a mesh screen onto paper or fabric. Areas blocked by a stencil resist the ink, allowing bold flat color and repeated editions.

A bronze-casting method in which a wax model is coated in clay, heated so the wax melts away, and replaced by molten metal. The process allows detailed, hollow, and complex sculptural forms.

A mural painting technique in which pigments mixed with water are applied to fresh, damp lime plaster. As the plaster cures, the color bonds with the wall, making it durable but requiring fast, confident work.

A slow-drying paint made of pigment suspended in a drying oil, usually linseed. Its long working time allows blending and glazing, and it can be applied thinly or built up in thick impasto layers.

A paint made from pigment bound in gum arabic and diluted with water. Watercolor is transparent and fluid; artists work from light to dark because pale washes cannot easily cover darker passages.

A dry drawing medium made from charred wood or other organic material. Charcoal produces soft, smudgy marks with deep blacks and is easily erased or blended, making it popular for sketches and studies.

The study of an artwork's visual elements and principles-line, shape, color, balance, and so on-rather than its subject matter or historical context. Formal analysis explains how composition produces meaning and effect.

The identification and interpretation of the subjects, symbols, and motifs in an artwork. Iconography goes beyond what is depicted to explain what those images meant to the artist's original audience.

The documented history of ownership of an artwork, from its creation to the present. Provenance helps establish authenticity, legal title, and exhibition history, and gaps can raise questions about a work's legitimacy.

An Italian term describing a figure posed with weight shifted onto one leg, so hips and shoulders tilt in opposite directions. The pose creates a natural, relaxed S-curve and was central to classical and Renaissance sculpture.

The dramatic use of strong contrasts between light and dark to model forms and create depth. Developed in the Renaissance and pushed further in the Baroque, it heightens volume and emotional intensity.

A painting technique of blending tones so gradually that edges become soft and smoky, with no visible transitions. Leonardo da Vinci famously used sfumato to create subtle, lifelike faces and atmospheric depth.

A late nineteenth-century French movement focused on capturing fleeting effects of light and atmosphere. Artists painted outdoors with broken brushstrokes and bright, unmixed colors, often finishing works quickly.

An early twentieth-century movement, led by Picasso and Braque, that broke subjects into geometric facets and showed multiple viewpoints at once. Cubism flattened space and influenced collage and abstract art.

A twentieth-century movement that explored dreams, the unconscious, and irrational juxtapositions. Some Surrealists painted highly illusionistic scenes, while others used automatism and biomorphic forms to bypass rational control.

An ordinary manufactured object selected by an artist and presented as art, often with little or no alteration. Marcel Duchamp's readymades challenged the idea that art must be handmade or beautiful.

Artists or movements that push beyond established conventions and are seen as ahead of their time. The term comes from military language and implies experimentation, risk, and opposition to mainstream taste.
