Camaïeu
''Camaïeu'' (also called ''en camaïeu'') is a technique that employs two or three tints of a single color, other than gray, to create a monochromatic image without regard to local or realistic color. When a picture is monochromatically rendered in gray, it is called grisaille; when in yellow, cirage. The term is also applied to monochrome painting in enamels. This technique uses a buildup of white enamel to create highlights and light areas. However, instead of using a black background, as in grisaille, transparent enamel is laid in first, beneath the whites. This technique is frequently used on snuffboxes, watches and medallions. ' can also refer, following the French usage, to chiaroscuro woodcut prints In molecular biology, the PRINTS database is a collection of so-called "fingerprints": it provides both a detailed annotation resource for protein families, and a diagnostic tool for newly determined sequences.

Tint
In color theory, a tint is a mixture of a color with white, which increases lightness, while a shade is a mixture with black, which increases darkness. Both processes affect the resulting color mixture's relative saturation. A tone is produced either by mixing a color with gray, or by both tinting and shading. Mixing a color with any neutral color (including black, gray, and white) reduces the chroma, or colorfulness, while the hue (the relative mixture of red, green, blue, etc. depending on the colorspace) remains unchanged. In the graphic arts, especially printmaking and drawing, "tone" has a different meaning, referring to areas of continuous color, produced by various means, as opposed to the linear marks made by an engraved or drawn line. In common language, the term ''shade'' can be generalized to encompass any varieties of a particular color, whether technically they are shades, tints, tones, or slightly different hues. Meanwhile, the term ''tint'' can be gener ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Color
Color (American English) or colour (British English) is the visual perceptual property deriving from the spectrum of light interacting with the photoreceptor cells of the eyes. Color categories and physical specifications of color are associated with objects or materials based on their physical properties such as light absorption, reflection, or emission spectra. By defining a color space, colors can be identified numerically by their coordinates. Because perception of color stems from the varying spectral sensitivity of different types of cone cells in the retina to different parts of the spectrum, colors may be defined and quantified by the degree to which they stimulate these cells. These physical or physiological quantifications of color, however, do not fully explain the psychophysical perception of color appearance. Color science includes the perception of color by the eye and brain, the origin of color in materials, color theory in art, and the physics of electr ...

Monochromatic
A monochrome or monochromatic image, object or color scheme, palette is composed of one color (or lightness, values of one color). Images using only Tint, shade and tone, shades of grey are called grayscale (typically digital) or Black and white, black-and-white (typically analog). In physics, Monochromatic radiation, monochromatic light refers to electromagnetic radiation that contains a narrow band of wavelengths, which is a distinct concept. Application Of an image, the term monochrome is usually taken to mean the same as black and white or, more likely, grayscale, but may also be used to refer to other combinations containing only tones of a single color, such as green-and-white or green-and-red. It may also refer to Sepia tone, sepia displaying tones from light tan to dark brown or cyanotype ("blueprint") images, and early photographic methods such as daguerreotypes, ambrotypes, and tintypes, each of which may be used to produce a monochromatic image. In computing, monoc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grisaille
Grisaille ( or ; french: grisaille, lit=greyed , from ''gris'' 'grey') is a painting executed entirely in shades of grey or of another neutral greyish colour. It is particularly used in large decorative schemes in imitation of sculpture. Many grisailles include a slightly wider colour range. Paintings executed in brown are referred to as ''brunaille'', and paintings executed in green are called ''verdaille''. A grisaille may be executed for its own sake, as an underpainting for an oil painting (in preparation for glazing layers of colour over it) or as a model from which an engraver may work (as was done by Rubens and his school). Full colouring of a subject makes many demands of an artist, and working in grisaille was often chosen as it may be quicker and cheaper than traditional painting, although the effect was sometimes deliberately chosen for aesthetic reasons. Grisaille paintings resemble the drawings, normally in monochrome, that artists from the Renaissance on were tra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snuffbox
A decorative box is a form of packaging that is generally more than just functional, but also intended to be decorative and artistic. Many such boxes are used for promotional packaging, both commercially and privately. Historical objects are usually called caskets if larger than a few inches in more than one dimension, with only smaller ones called boxes. Gift box Traditionally gift boxes used for promotional and seasonal gifts are made from sturdy paperboard or corrugated fiberboard. These boxes normally consist of a base and detachable lid and are made by using a die cutting process to cut the board. The box is then covered with decorative paper. Gift boxes can be dressed with other gift packaging material, such as decorative ribbons and gift tissue paper. Work box The most common type of decorative box is the feminine work box. It is usually fitted with a tray divided into many small compartments for needles, reels of silk and cotton, and other necessaries for stitchery. ...

Chiaroscuro
Chiaroscuro ( , ; ), in art, is the use of strong contrasts between light and dark, usually bold contrasts affecting a whole composition. It is also a technical term used by artists and art historians for the use of contrasts of light to achieve a sense of volume in modelling three-dimensional objects and figures. Similar effects in cinema, and black and white and low-key photography, are also called chiaroscuro. Further specialized uses of the term include chiaroscuro woodcut for coloured woodcuts printed with different blocks, each using a different coloured ink; and chiaroscuro drawing for drawings on coloured paper in a dark medium with white highlighting. Chiaroscuro is one of the canonical painting modes of the Renaissance (alongside cangiante, sfumato and unione) (see also Renaissance art). Artists known for using the technique include Leonardo da Vinci, Caravaggio Rembrandt, Vermeer and Goya, and Georges de La Tour. History Origin in the chiaroscuro drawing The term ...

Woodcut
Woodcut is a relief printing technique in printmaking. An artist carves an image into the surface of a block of wood—typically with gouges—leaving the printing parts level with the surface while removing the non-printing parts. Areas that the artist cuts away carry no ink, while characters or images at surface level carry the ink to produce the print. The block is cut along the wood grain (unlike wood engraving, where the block is cut in the end-grain). The surface is covered with ink by rolling over the surface with an ink-covered roller (brayer), leaving ink upon the flat surface but not in the non-printing areas. Multiple colors can be printed by keying the paper to a frame around the woodblocks (using a different block for each color). The art of carving the woodcut can be called "xylography", but this is rarely used in English for images alone, although that and "xylographic" are used in connection with block books, which are small books containing text and images in t ...

Old Master Print
An old master print is a work of art produced by a printing process within the Western tradition. The term remains current in the art trade, and there is no easy alternative in English to distinguish the works of "fine art" produced in printmaking from the vast range of decorative, utilitarian and popular prints that grew rapidly alongside the artistic print from the 15th century onwards. Fifteenth-century prints are sufficiently rare that they are classed as old master prints even if they are of crude or merely workmanlike artistic quality. A date of about 1830 is usually taken as marking the end of the period whose prints are covered by this term. The main techniques used, in order of their introduction, are woodcut, engraving, etching, mezzotint and aquatint, although there are others. Different techniques are often combined in a single print. With rare exceptions printed on textiles, such as silk, or on vellum, old master prints are printed on paper. This article is concerned ...

Cameo (carving)
Cameo () is a method of carving an object such as an engraved gem, item of jewellery or vessel. It nearly always features a raised (positive) relief image; contrast with intaglio, which has a negative image. Originally, and still in discussing historical work, cameo only referred to works where the relief image was of a contrasting colour to the background; this was achieved by carefully carving a piece of material with a flat plane where two contrasting colours met, removing all the first colour except for the image to leave a contrasting background. A variation of a carved cameo is a cameo incrustation (or sulphide). An artist, usually an engraver, carves a small portrait, then makes a cast from the carving, from which a ceramic type cameo is produced. This is then encased in a glass object, often a paperweight. These are very difficult to make but were popular from the late 18th century through the end of the 19th century. Originating in Bohemia, the finest examples were mad ...
