Study Notes
Poster Colours
- More pigmented than water colours and tempera colours, eliminating the need for glue size addition before use
- Can be mixed with water and applied with a brush to create a desired consistency
- Must be mixed to a medium consistency before use to avoid brush marks
- Suitable for indoor works and Graphic communication design projects
Acrylic Colours
- Opaque water-based paints containing synthetic resin(s) as binder, fine coloured pigment, and drier
- Fast-drying with good opacity, elasticity, flow, adhesion, and water resistance
- Available in small and big containers, and in paste form in tubes
- Drying rate can be retarded by adding a little linseed oil, often used for large realistic mural paintings
- Suitable for all kinds of paintings and Graphic communication design works
- Can be used to prime fabric, wood, and cement walls
- Can be sprayed with vanish or lacquer upon drying to improve brightness and durability
Techniques for Rendering Flat Paintings
- Silhouette technique: painting the object or scene in one flat colour
- Outline silhouette: painting the outlines of the object with one flat colour
- Block or two-dimensional silhouette: painting the entire shape of the object with one flat colour
- Three-dimensional silhouette: creating the illusion of solidity or three-dimensionality in the object by adding light and dark tones
