Pastel in the context of Prismacolor

A crayon (or wax pastel) is a stick of pigmented wax used for writing or drawing. Wax crayons differ from pastels, in which the pigment is mixed with a dry binder such as gum arabic, and from oil pastels, where the binder is a mixture of wax and oil.

Crayons are available in a range of prices, and are easy to work with. They are less messy than most paints and markers, blunt (removing the risk of sharp points present when using a pencil or pen), typically non-toxic, and available in a wide variety of colors. These characteristics make them particularly good instruments for teaching small children to draw in addition to being used widely by student and professional artists.

Hand-colouring (or hand-coloring) refers to any method of manually adding colour to a monochrome photograph, generally either to heighten the realism of the image or for artistic purposes. Hand-colouring is also known as hand painting or overpainting.

Typically, watercolours, oils, crayons or pastels, and other paints or dyes are applied to the image surface using brushes, fingers, cotton swabs or airbrushes. Hand-coloured photographs were most popular in the mid- to late-19th century before the invention of colour photography, and some firms specialized in producing hand-coloured photographs.

Caran d'Ache (French pronunciation: [kaʁɑ̃ daʃ]) is a Swiss manufacturing company of art materials and writing instruments. The company, established in 1915, produces a wide range of products including colored pencils, graphite pencils, pastels, fountain pens, ballpoint pens, mechanical pencils, markers, gouache paints, and ink cartridges.

Oil pastel is a type of pastel (an art medium that consists of powdered pigment and a binder) that uses mixture of non-drying oil and wax as binder. It differs from other pastels which are made with a gum or methyl cellulose binder, and from wax crayons which are made without oil. The surface of an oil pastel painting is less powdery than one made from other pastels, but more difficult to protect with a fixative. The colors of oil pastels are highly saturated and bright. They can be blended easily but they can break easily too.

In color theory, hue is one of the properties (called color appearance parameters) of a color, defined in the CIECAM02 model as "the degree to which a stimulus can be described as similar to or different from stimuli that are described as red, orange, yellow, green, blue, violet," within certain theories of color vision.

Hue can typically be represented quantitatively by a single number, often corresponding to an angular position around a central or neutral point or axis on a color space coordinate diagram (such as a chromaticity diagram) or color wheel, or by its dominant wavelength or by that of its complementary color. The other color appearance parameters are colorfulness, saturation (also known as intensity or chroma), lightness, and brightness. Usually, colors with the same hue are distinguished with adjectives referring to their lightness or colorfulness - for example: "light blue", "pastel blue", "vivid blue", and "cobalt blue". Exceptions include brown, which is a dark orange.

A sketch (ultimately from Greek σχέδιος – schedios, "done extempore") is a rapidly executed freehand drawing that is not usually intended as a finished work. A sketch may serve a number of purposes: it might record something that the artist sees, it might record or develop an idea for later use or it might be used as a quick way of graphically demonstrating an image, idea or principle. Sketching is the most inexpensive art medium.

Sketches can be made in any drawing medium. The term is most often applied to graphic work executed in a dry medium such as silverpoint, graphite, pencil, charcoal or pastel. It may also apply to drawings executed in pen and ink, digital input such as a digital pen, ballpoint pen, marker pen, water colour and oil paint. The latter two are generally referred to as "water colour sketches" and "oil sketches". A sculptor might model three-dimensional sketches in clay, plasticine or wax.

Pastels or pastel colors belong to a pale family of colors, which, when described in the HSV color space, have high value and low or medium saturation. They are named after the artistic medium made from pigment and solid binding agents, similar to crayons. Pastel sticks historically had lower saturation than paints of the same pigment, hence the name of this color family.

The colors of this family are usually described as soothing, calming, and nostalgic. They tend to lean towards ideas of simplicity and help to contrast against the bolder and brighter colors that trend in our world. They are integrated into interior design in many places, such as healthcare to help soothe anxiety, or in classrooms to help the mind focus. Pastel colors work to oppose the brighter, bolder colors that tend to be common in many other places.

In art, in particular drawings in pastels, charcoal, chalk, and other dry media, a fixative is a kind of preserving agent applied over the top of the drawing to prevent crumbling, smudging, fading, and discolouring.In times gone by, natural substances such as diluted egg white were painted on, but today synthetic sprays are usually used. However some artists, such as the Aboriginal Australian artists at Warmun, Western Australia, use traditional substances, in this case gum gathered from local bloodwood trees.

Fixative is similar to varnish, but there are some key differences. Varnish is often used to protect paintings from atmospheric moisture, sunlight and dust; it helps to protect from being scratched, and makes the colours brighter. Fixatives prevents smearing.

Sir Thomas Lawrence PRA FRS (13 April 1769 – 7 January 1830) was an English painter who served as the fourth president of the Royal Academy. A child prodigy, he was born in Bristol and began drawing in Devizes, where his father was an innkeeper at the Bear Hotel in the Market Square. At age ten, having moved to Bath, he was supporting his family with his pastel portraits.

At 18, he went to London and soon established his reputation as a portrait painter in oils, receiving his first royal commission, a portrait of Queen Charlotte, in 1789. He stayed at the top of his profession until his death, aged 60, in 1830. Self-taught, he was a brilliant draughtsman and known for his gift of capturing a likeness, as well as his virtuoso handling of paint. He became an associate of the Royal Academy in 1791, a full member in 1794, and president in 1820.

Maurice Quentin de La Tour (French pronunciation: [mɔʁis kɑ̃tɛ̃ də la tuʁ]; 5 September 1704 – 17 February 1788) was a French painter who specialised in portrait painting using pastels in the Rococo style. Among his most famous subjects were Voltaire, Jean-Jacques Rousseau, Louis XV, and Madame de Pompadour.

William Hoare, RA (c. 1707 – 12 December 1792) was an English painter. From 1740 to 1759, he was the leading oil portraitist at Bath, Somerset until Thomas Gainsborough arrived in the town. Noted for his pastels, Hoare was a co-founder of the Royal Academy of Arts.

The Kupferstichkabinett, or Museum of Prints and Drawings, is a prints museum in Berlin, Germany. It is part of the Berlin State Museums, and is located in the Kulturforum on Potsdamer Platz. It is the largest museum of graphic art in Germany, with more than 500,000 prints and around 110,000 individual works on paper (drawings, pastels, watercolours, oil sketches).

Eugène Louis Boudin (French: [øʒɛn lwi budɛ̃]; 12 July 1824 – 8 August 1898) was one of the first French landscape painters to paint outdoors. Boudin was a marine painter, and expert in the rendering of all that goes upon the sea and along its shores. His pastels, summary and economic, garnered the splendid eulogy of Baudelaire; and Corot called him the "King of the skies".

Jean-Louis Forain (French pronunciation: [ʒɑ̃ lwi fɔʁɛ̃]; 23 October 1852 – 11 July 1931) was a French Impressionist painter and printmaker, working in media including oils, watercolour, pastel, etching and lithograph. Compared to many of his Impressionist colleagues, he was more successful during his lifetime, but his reputation is now much less exalted.
