Painting is the art of using pigments to apply colour to a surface such as paper or canvas to create pictures. The pigment may be in a wet form, such as paint, or a dry form, such as pastels.
Some artists create realisting paintings:
Others create abstract paintings:
Each type of paint has its own unique qualities, advantages and disadvantages. Which you select will depend on the effect you want to achieve.
Watercolour comes in metal tubes or as dry tablets that need to be mixed with water. It also comes in a liquid form that is commonly used for airbrushing.
Watercolour paint is a translucent medium suitable for many purposes. Watercolour is often used to create a muted, subtle image and has a softened look.
Watercolour can be a good choice if you want to work quickly or if you are on location as it requires little extra equipment, dried quickly and can be cleaned from brushes with just water.
A drawback of using watercolour is that it is difficult to fix mistakes. You need to know what you are doing because you can't make changes by painting over them. You also need to be careful that you don't damage the surface you are using by repeatedly wetting it.
While ink can be used with a pen to create drawings, it can also be used in a similar way to watercolour.
Used on its own, ink gives a rich, glossy result. When mixed with water it becomes transparent and can create subtle variation of tone and colour.
Inks come in bright colours which can create vibrant results. The more these are mixed with water, the more muted they become. Mixing complementary colours will also tone down the brightness.
As with watercolours, you should mix coloured inks together before you apply them to your paper.
Oil paint is rich and vibrant. Oil paintings are often very detailed and colourful and are composed of many layers of paint.
Oil paint is a permanent and durable medium. However it is expensive and can take a very long time to dry - between six months and a whole year where there are many layers.
Like oil paint, acrylic paint is well-suited for detail, but it is easy to use.
Depending on the technique used by the artist, acrylic can produce results that are like oil or watercolor.
Acrylics are water-based which means they can be cleaned from brushes more easily.
Acrylic dries very quickly so should be kept moist on the palette to prevent drying out.
Work created with pastels can be compared to painting or drawing. When a whole surface is covered with pastel, the result is often called a pastel painting. A pastel drawing has parts of the surface showing through.
Pastels usually come in the form of sticks that consist of pure powdered pigment and a binder. An artwork made using pastels is called a pastel, a pastel painting or a pastel drawing.
Chalk pastels have a soft, matt quality and are easy to use. Colours can be blended by overlaying and using smudging techniques. A dusty surface is created and a fixative is needed to keep in place.
Oil pastels are also made from pigments but are combined with waxes and fats. They are good for paintings with strong colours. They are slightly harder to blend than chalk pastels but have the advantage that they do not need a fixative.
Oil pastels can be combined with other materials such as inks or watercolours then scraped away in sections to give a wax resist effect. White spirit can be used to create a more painterly effect.
