Watercolour

Correct answer: D. Add more water to brown

Explanation: In transparent watercolour, the value or lightness of a colour is mainly controlled by the amount of water. Adding more clean water to brown spreads the pigment into a paler, lighter transparent wash, so option D is correct. Black would make the brown darker, oil is unsuitable for ordinary watercolour paper, and a thick layer generally increases darkness rather than producing a delicate light tone.

Correct answer: A. The whiteness of the paper

Explanation: Watercolour is usually transparent, so the artist often preserves the untouched white paper to represent highlights and the brightest areas of light. Therefore option A is correct. Black paint produces dark values, while oil and glue do not provide a suitable or standard method for showing light in a normal watercolour painting. Planning the white spaces before painting is especially useful.

Correct answer: C. With a controlled brush on dry paper

Explanation: The wet-on-dry method is suitable when a clean, controlled edge is required. On dry paper, the pigment does not travel freely, and a steady brush can place colour within a defined boundary, making option C correct. Very wet paper and excess water encourage spreading and softer edges, while folding the paper has no useful role in controlling a painted edge.

Correct answer: D. Let it dry completely

Explanation: A watercolour painting should be allowed to dry completely before it is stored. Drying prevents wet pigment from smearing, sticking to another surface, or becoming damaged by pressure, so option D is correct. Folding while wet can transfer or crack the paint, rubbing removes pigment, and adding oil changes the surface and is not a normal preservation step for a school watercolour.

Correct answer: A. Create a light-to-dark wash of one colour

Explanation: A light-to-dark wash using one colour is an effective beginner exercise because it develops control over water, pigment concentration, brush movement, and gradual value change. Therefore option A is correct. A complex painting introduces too many skills at once, mixing all colours usually creates a dull muddy result, and covering the paper in black does not practise controlled tonal transitions.

Correct answer: B. Graded wash

Explanation: A graded wash is a watercolour wash in which the value changes progressively, usually from a stronger or darker mixture toward a lighter, more diluted one. Thus option B is correct. A dry line describes a mark rather than a gradual wash, a thick layer refers to paint quantity, and a metallic effect describes appearance, not a controlled light-to-dark change in value.

Correct answer: C. Flat wash

Explanation: A flat wash is applied so that the colour and value remain as even as possible across the painted area. Therefore option C is correct. A graded wash deliberately changes from light to dark, while wet mixture is a general description rather than the name of this uniform technique. Dry shadow is not the standard term for an evenly coloured watercolour wash.

Correct answer: D. The colour may spread uncontrollably

Explanation: Watercolour depends on a balance between pigment and water. If the brush carries excessive water, it can flood the painted area, push pigment outward, create blooms, and make the spread difficult to control; therefore option D is correct. Extra water usually makes paint thinner, not thicker. It does not harden the brush, and it cannot leave the paper dry where it is applied.

Correct answer: A. Prepare a light outline, colour plan, and materials

Explanation: Before beginning, a light outline, a simple colour plan, and organised materials help the artist preserve important shapes, choose suitable colours, and work without unnecessary interruptions. Thus option A is correct. Mixing all colours creates a dull mixture, oil can interfere with the paper and watercolour absorption, and dirty water contaminates clean colours and reduces their brightness.

Correct answer: B. Practise flat wash, graded wash and wet-on-wet

Explanation: The governing concept is technique practice: watercolour depends on controlling pigment, water and brush movement. Flat wash develops an even layer, graded wash develops a smooth change from dark to light, and wet-on-wet teaches controlled spreading on damp paper. Therefore, option B directly builds practical watercolour skills; writing names, folding paper and keeping a dirty brush do not develop painting control.

Correct answer: A. Water

Explanation: The governing concept is the painting medium: watercolour pigment is designed to be reactivated and dispersed in water. Adding water makes the paint workable and allows the artist to create transparent washes, while the amount of water controls lightness and spread. Thus option A is correct. Oil, sand and wax do not dissolve ordinary watercolour paint and cannot provide its normal fluid working medium.

Correct answer: B. They are generally transparent

Explanation: The governing concept is transparency in watercolour painting. Because the paint is diluted with water and applied in relatively thin layers, the white of the paper can show through the colour. This gives watercolours their light, luminous appearance. Therefore option B is correct. They are not completely opaque, they are not restricted to metal, and they do dissolve or disperse in water.

Correct answer: B. Water

Explanation: The governing concept is dilution and pigment-to-water ratio. When more water is added to the same amount of pigment, the mixture becomes less concentrated, so the applied colour appears lighter and more transparent. Therefore option B is correct. Adding black increases darkness, while glue and sand are not normal materials for lightening a watercolour wash. A lighter tone is usually made with water rather than white paint.

Correct answer: A. Increase the amount of pigment

Explanation: The governing concept is colour intensity, which is strongly affected by the pigment-to-water ratio. To obtain a darker wash, use more pigment or relatively less water, increasing the concentration deposited on the paper. Therefore option A is correct. More water generally dilutes the colour, and soaking the paper or applying only water does not add pigment or create a darker tone.

Correct answer: A. Palette

Explanation: The governing concept is the function of painting tools. A palette provides a clean surface or separate wells where pigments can be combined with one another and adjusted with water before application. Thus option A is correct. A water container mainly supplies rinsing water, a brush transfers and blends paint on the work, and a drawing sheet is the painting surface rather than the mixing tool.

Correct answer: A. Leave the white paper unpainted

Explanation: The governing concept is the use of the paper white in transparent watercolour. Since white watercolour paint is not normally used to cover every light area, the artist plans highlights and leaves those parts unpainted so the white paper reflects light. Therefore option A is correct. Black or dark paint removes the light effect, while tearing the paper damages the support rather than creating a controlled white area.

Correct answer: B. Clean

Explanation: The governing concept is clean tool control in watercolour. A clean, properly rinsed brush prevents leftover pigment from contaminating the next colour and keeps mixtures bright rather than muddy. Therefore option B is correct. A dirty brush introduces unwanted colour, while a broken or sand-filled brush cannot make controlled marks. The brush may hold a suitable amount of clean water, but it should not carry residue.

Correct answer: A. The colour becomes lighter and more transparent

Explanation: The governing concept is dilution: extra water lowers the concentration of pigment in the mixture. As a result, the colour appears lighter and more transparent, and on absorbent or damp paper it may spread farther than intended. Therefore option A is correct. Too much water does not make the paint darker or opaque, does not ensure immediate drying, and does not create a permanent surface shine.

Correct answer: A. To wash brushes and dilute colour

Explanation: The governing concept is water as the working medium of watercolour. A water container lets the artist rinse pigment from the brush before changing colours and add controlled water to adjust wash thickness, transparency and spread. Therefore option A is correct. Water does not permanently fix paint, roughen the paper or erase the drawing outline; those are unrelated functions.

Correct answer: A. Wet-on-wet

Explanation: The governing concept is the condition of the surface and the paint. When wet watercolour is applied to paper that is already wet, the method is called wet-on-wet, so option A is correct. Moisture allows the pigment to spread softly and creates diffused edges. Wet-on-dry uses wet paint on dry paper and usually gives sharper edges; the other combinations do not describe this process.

Correct answer: B. Wet-on-dry

Explanation: The governing concept is the relationship between the wet paint and the paper surface. Applying wet watercolour to dry paper is called wet-on-dry, making option B correct. Because the paper is not moist, the pigment spreads less freely and produces clearer, more controlled edges. Wet-on-wet requires wet paper, dry-on-dry involves dry material on a dry surface, and clay painting is unrelated.

Correct answer: A. Soft and blurred

Explanation: The governing concept is pigment diffusion on a moist surface. In the wet-on-wet method, both the paper and the paint contain moisture, so the colour moves gradually into the surrounding damp area. This produces soft, blurred edges, making option A correct. Hard edges are more typical of wet-on-dry painting, while metallic and invisible effects are not normal results of this method.

Correct answer: A. Clear

Explanation: The governing concept is controlled paint movement on a dry surface. In wet-on-dry, wet watercolour is placed on dry paper or a dry painted layer, so the moisture does not allow the pigment to spread widely. The edges therefore remain clear and well defined, making option A correct. Soft, blurred edges are associated with wet-on-wet; broken or invisible edges are not the normal result.

Correct answer: A. Wash

Explanation: The governing concept is a broad, diluted and transparent application of watercolour. A first overall layer spread across a large area is commonly called a wash, so option A is correct. It establishes a light base before later details are added. A glaze is a transparent layer usually placed over a dry layer to modify colour, dry brush uses little water for texture, and impasto is thick raised paint, not typical watercolour practice.

Correct answer: A. Create an even area of colour

Explanation: The governing concept of a flat wash is uniform coverage. The artist prepares a consistent mixture of pigment and water and spreads it across the area so that the colour remains as even as possible from one side to the other. Therefore, option A is correct. Cutting paper, making a sculpture, and erasing lines are separate activities and are not purposes of a watercolour wash.
