calligraphy- Decorative or ornamental lettering or handwriting.
canvas A fabric support, generally used for oil and acrylic painting. Traditionally made from linen and hemp, now often made from cotton. Synthetic fibres such as polyester are being introduced that offer some advantages over natural fibres as painting supports. Canvas can be stretched over a frame or applied to a hard surface such as heavy cardboard or hardboard.
canvas scraper - A tool with a curved blade used to scrape oil or acrylic paint from a
cardboard - Stiff paper of varying thickness. Includes illustration board, corrugated cardboard and foam core board.
caricature Exaggerating or distorting the feature of a subject. Often used for comic effect on facial and body features, especially on political subjects.
cartoon - A drawing often with a story and captions. Usually for amusement, it can be used for educational purposes or to provoke an emotional response to a subject. A cartoon was also an Old Masters technique of making life sized drawings and then transferring these to a support by brushing charcoal over pinholes set in the drawing, often used in large fresco works.
casein paint Paint made using milk protein as the binder. Water-soluble when applied, it becomes increasingly insoluble over time. Noted for its matt finish.
charcoal - Compressed burned wood used in drawing. Can be made with different woods in for varying degrees of hardness.

china marker A marker for drawing on or marking smooth surfaces. Also known as grease or wax pencils.
chipboard see hardboard
chroma One of the three colour attributes; the relative intensity or purity of a colour. A colour with low chroma is closer to gray; a colour with high chroma would be seen as luminous or intense. Saturation is a related term. See also hue and value.
chromatic pigments Pigments which are not black, white or gray.
cinnabar - A red mineral, mercuric sulphide, used as a pigment in the past. Vermilion is the synthetic version of cinnabar.
circumscribe In drawing, to enclose or outline and object.
cissing- In painting, streaks, bare spots, running paint (normally from over-wetting). Usually a mistake, the desired result being uniform coverage, but poor technique causes the streaking and incomplete coverage.
classical A painting style which is harmonious, elegant and simple, usually realist and often adopting the methods of painters from the 16th to the early 20th century.
clayboard a hardboard panel coated with a smooth absorbant clay ground. The boards are archival, lightfast and acid free.

collage A work created by gluing materials e.g. paper, cloth, to a backing material, often producing works of great surface texture with three dimensional effects.
color When light strikes an object and is reflected back into the eyes part of the spectrum of the light is absorbed by the object. The remaining elements of the spectrum which then hit the eye constitute the color of the object. See the Color Theory and Mixing forum
color bias The leaning of a colour towards an adjacent hue, if any, e.g. Cadmium Scarlet is an orange-biased red, Cerulean Blue is a green-biased blue. Although some pigment and paint names do not follow this convention, only adjacent hues should be referred to; for example a yellow cannot be biased to blue or red, only to green or orange and so on.
color scheme The palette or colors used in a work.

color wheel - An illustration or diagram of colors arranged in a circle in which the primary, secondary and often intermediate colors are displayed in their relation to one another to aid selection and mixing. Two common wheels are based on the RYB (red, yellow, blue) or the CMY (cyan, magenta, yellow) system of color relationships.
commission An order, contract or authority given to an artist to produce a work. It may also refer to the fee charged by a gallery or agent when selling works to a third party.
complementary colors Visually, complements are the colours directly opposite one another on the colour wheel, e.g. magenta and green. In paints, the colour or colors that mix with another to form a neutral gray; these two colours are called a complementary pair
composition The arrangement of the elements of an artwork. Often one of the most important factors in the success of a work and vital in the planning process for a work. See the Composition and Design Forum.
compressor An electrical pump, often with a storage cylinder, used as the air supply to power airbrushes and spray guns.

consign and consignment Transferring a work to an agent or retailer who then sells the work on behalf of the artist, taking a previously agreed commission as part of the transaction.
Contι crayon A variety of fabricated chalk, the crayons originally consisted of a combination of powdered graphite and clay. They are now a very firm type of pastel and are useful in detailed work. Known for their classic earth colors sanguine, bistre, black, and also their whites and grays.
context The circumstances in which a work is produced and interpreted. The production circumstances revolve around the artist and the life experiences and values that form the person. The interpretive area involves the setting of the work, its intended use or function, the socio-economic, political or religious conditions contributing to the formation of the work.

contrast The difference between two objects or areas in a work e.g. light values and dark values, high chroma and low chroma, hard edges and soft edges.
contrived Lacking spontaneity and inspiration. The work can be technically correct but can seem artificial, lacking life.
cool colors Cool colors suggest cool temperatures and are usually blues, greens and violets. The blues especially are associated with distance or recession in a painting. The cool colors are often used in water, skies and foliage, and in cool shadow areas. See color temperature.
copal Any of a number of hard natural resins, originally semi-fossilized, used to make varnishes and painting mediums for many centuries. No longer used in picture varnishes because it darkens badly and can tend to form cracks, still in use by some oil painters in mediums. There are synthetic resin varnishes sold under the name copal.
copyright A legal term, it is the right granted to a creator to exclusive publication, production, sale or distribution of a work.

DPI (dots per inch) In digital images, the number of pixels per inch of image. The higher the number of pixels per inch the greater the clarity of the image.
dragging Lightly moving a brush loaded with paint over a surface, leaving areas of broken color as the paint adheres only to the high spots of the surface..
drawing - Portraying objects, forms or scenes through the use of lines, color, or shading. A discipline of art which can be taken to great heights in its own right, it is often the foundation of many paintings. See the Drawing and Sketching Forum.
drier An additive that accelerates the drying of oil paints by promoting oxidation. Also called a siccative. Some pigments have a natural drying property when bound in drying oils, such as those containing lead and manganese.
