Acrylic paint in the context of Cel animation

Gouache (/ɡuˈɑːʃ, ɡwɑːʃ/; French: [ɡwaʃ]), body color, or opaque watercolor is a water-medium paint consisting of natural pigment, water, a binding agent (usually gum arabic or dextrin), and sometimes additional inert material. Gouache is designed to be opaque. Gouache has a long history, having been used for at least twelve centuries. It is used most consistently by commercial artists for posters, illustrations, comics, and other design work.

Gouache is similar to watercolor in that it can be rewetted and dried to a matte finish, and the paint can become infused into its paper support. It is similar to acrylic or oil paints in that it is normally used in an opaque painting style and it can form a superficial layer. Many manufacturers of watercolor paints also produce gouache, and the two can easily be used together.

Traditional animation (or classical animation, cel animation, or hand-drawn animation) is an animation technique in which each frame is drawn by hand. The technique was the dominant form of animation of the 20th century in the United States until there was a shift to computer animation in the industry, such as 3D computer animation. Despite this, the process remains commonly used primarily in the form of digital ink and paint for television and film, especially when outsourced.

A cel, short for celluloid, is a transparent sheet on which objects are drawn or painted for traditional, hand-drawn animation. Actual celluloid (consisting of cellulose nitrate and camphor) was used during the first half of the 20th century. Since it was flammable and dimensionally unstable, celluloid was largely replaced by cellulose acetate (cellulose diacetate and cellulose triacetate) and polyester. With the advent of computer-assisted animation production (also known as digital ink and paint), the use of cels has been all but obsolete in major productions. Walt Disney Animation Studios stopped using cels in 1990, when Computer Animation Production System (CAPS) replaced this element in their animation process. In the next decade and a half, other animation studios phased cels out as well in favor of digital ink and paint.

A picture book combines visual and verbal narratives in a book format, most often aimed at young children. With the narrative told primarily through text, they are distinct from comics, which do so primarily through sequential images.

The images in picture books can be produced in a range of media, such as oil paints, acrylics, watercolor, and pencil. Picture books often serve as educational resources, aiding with children's language development or understanding of the world.

A palette (/ˈpælɪt/) is a surface on which a painter arranges and mixes paints. A palette is made of materials such as wood, paper, glass, ceramic or plastic, and can vary greatly in size and shape. Watercolor palettes are generally made of plastic or porcelain in a rectangular or wheel format, and have built in wells and mixing areas for colors. For acrylic painting, "stay wet" palettes exist, which prevent the paints from drying out and becoming inert.

A classical palette is most often oval, but can also be rectangular, and is tapered to ensure optimal distribution of weight. It has a thumbhole and insert for brushes, and is designed to be held in the non-dominant hand while the other is used to mix and paint. However, some well-known artists have used more unconventional palettes; for instance, Picasso used a sheet of newspaper.

Berol (stylised as Bẽrol) is a British stationery brand of Newell Brands and former stationery manufacturing company, based in Lichfield, Staffordshire. The company was established in 1856 and manufactured a wide range of products including writing implements and art materials. It was acquired by Sanford L.P. in 1995, a division of Newell Brands, becoming a subsidiary of it until the last factory closed in 2010. Since then, Berol has survived as a brand of imported products, though the head office remains in Lichfield.

Berol's product lines included art materials such as acrylics, pastels, oil pastels, inks, crayons, adhesives, and other mediums; while the writing instruments line composed of pencils, colored pencils, pens, and markers, plus accessories.
