What this dot point is asking
SEAB wants you to know the common types of paint, how each one behaves, and the basic tools you use with them. Different paints handle very differently, and choosing the right one and treating it properly makes painting far easier. This dot point is the practical foundation for the painting techniques and colour work that follow, and it gives you the vocabulary to describe how a painting was made.
The answer
The main painting media
- Watercolour is a transparent paint mixed with water. The white of the paper shows through, so you build colour in thin, glowing washes and use the paper for your lightest areas. It is luminous and delicate but unforgiving, because you cannot easily paint a light colour back over a dark one.
- Poster paint is an opaque, water-based paint that gives flat, bright, solid colour. It covers what is underneath, is cheap and easy to use, and is good for bold design work, though it can look chalky.
- Acrylic is a versatile opaque paint that can be thinned with water to act a little like watercolour or used thickly straight from the tube. It dries fast and waterproof, covers well, and lets you paint light over dark and correct mistakes.
Transparent versus opaque
The biggest practical difference is whether a paint is transparent or opaque. Transparent paint (watercolour) lets the surface show through, so you must plan your light areas in advance and work light to dark. Opaque paint (poster, acrylic) covers underneath, so you can paint dark first and add lights and highlights on top, and correct as you go. Knowing which kind you are using decides how you plan a painting.
Brushes and tools
The basic kit is: paints, a few brushes of different sizes (a large flat or round for big areas, a fine round for detail), a palette for mixing, a water pot, a cloth or paper towel, and the right surface (watercolour paper for watercolour, thicker paper or board for acrylic). Big brushes cover large areas smoothly; small brushes give control for detail. Using the right size for the job keeps your work clean and efficient.
Looking after paint and brushes
Good habits save trouble: rinse brushes well between colours so your mixes stay clean, never leave brushes standing on their bristles in water because it bends them permanently, and wash and reshape brushes after use so they keep their point. With acrylic, work fairly quickly and keep the lid on, because it dries fast and ruins brushes if it sets in them.
Examples in context
Example 1. A loose watercolour sky. A painter wets the paper and drops in pale blue and grey, letting the colours blend softly while leaving white paper for clouds. The luminous, soft result depends entirely on watercolour's transparency and on planning the white areas in advance, a clear lesson in handling a transparent medium.
Example 2. A bold acrylic still life. The same fruit painted in acrylic can be built dark first with bright highlights dabbed on top at the end. Because acrylic is opaque and covers, the artist can correct and adjust freely, showing how an opaque medium changes the working method.
Try this
Q1. Explain the difference between a transparent and an opaque paint. [2 marks]
- Cue. A transparent paint (watercolour) lets the surface show through, so you work light to dark; an opaque paint (poster, acrylic) covers what is underneath, so you can paint light over dark.
Q2. List four pieces of basic painting equipment and say what one of them is for. [3 marks]
- Cue. Paints, brushes of different sizes, a palette, a water pot and a cloth; for example, a large brush covers big areas and a small brush gives control for detail.
Q3. Give two ways to look after your brushes and explain why each matters. [2 marks]
- Cue. Rinse between colours so mixes stay clean; never stand brushes on their bristles in water because it bends them; wash and reshape after use so they keep their point.

Original6 marksExplain the difference between a transparent paint such as watercolour and an opaque paint such as poster or acrylic paint, and say what each is good for.Show worked answer →
Define both. A transparent paint such as watercolour lets the white of the paper show through, so you build colour up in thin washes and use the paper itself for the lightest areas. An opaque paint such as poster paint or acrylic covers what is underneath, so a light colour can be painted over a dark one.
Say what each suits. Watercolour suits soft, luminous, light effects such as skies and delicate washes, and you must plan light areas in advance because you cannot paint white back in easily. Opaque paint suits bold, solid blocks of colour and lets you correct or add highlights on top.
Markers reward a correct distinction (paper shows through versus covers underneath), the consequence for working method (plan lights versus paint over), and a suitable use for each.
Original5 marksDescribe the basic equipment you need to paint well and explain why looking after your brushes matters.Show worked answer →
List the basics: paints, a few brushes of different sizes (a large one for big areas, a small one for detail), a palette for mixing, a water pot, a cloth or paper towel, and the right surface (paper for watercolour, thicker paper or board for acrylic).
Explain brush care. Rinse brushes well between colours so mixes stay clean, never leave them standing on their bristles in water (it bends them), and wash and reshape them after use. Cared-for brushes keep their point for detail and last much longer.
Markers reward a sensible equipment list, the point that different brush sizes do different jobs, and clear reasons for looking after brushes.
