Watercolour

Correct answer: B. Clear and controlled

Explanation: Wet-on-dry means that moist watercolour is applied to a dry paper surface. Since the dry fibres absorb and restrict the movement of the paint, the mark generally stays within its applied area and forms clearer, more controlled edges, making option B correct. Blurred edges are associated with wet-on-wet, while invisible or torn-paper-like edges are not normal defining results of this technique.

Correct answer: C. A light pencil sketch

Explanation: The governing concept is preliminary planning in watercolour. A light pencil sketch helps the artist place the main shapes, proportions, and composition before adding transparent paint. It can usually remain subtle beneath the colour, whereas very dark lines may show through and distract from the painting. Holes and thick oil paint do not help plan a watercolour image, so option C is correct.

Correct answer: D. Darker colours can be added later easily

Explanation: The governing concept is the light-to-dark sequence used in transparent watercolour. Light washes preserve the paper and leave room to build stronger tones gradually. Once a very dark colour is placed, it is difficult to remove or make it completely lighter without disturbing the paper. Applying light colours first therefore makes later darker additions easier and safer. The other options describe effects that do not occur, so option D is correct.

Correct answer: A. Glazing

Explanation: The governing concept is glazing, a watercolour method in which a transparent wash is placed over a completely dry layer. Light passes through the upper wash and visually combines with the colour underneath, producing a new tone or richer effect. Folding paper, scratching paint, and erasing a line are different actions and do not describe transparent layered painting. Therefore option A is the precise technical term.

Correct answer: B. Let the first layer dry

Explanation: The governing concept is controlled layering in watercolour. The first wash should dry before a second wash is added, because a wet underlayer can cause the new colour to spread, lift, or mix unpredictably. Waiting preserves cleaner shapes, edges, and colour relationships. Tearing the paper, adding oil, or cutting the brush does not prepare the surface for a controlled watercolour layer. Thus option B is correct.

Correct answer: C. Colours may become muddy

Explanation: The governing concept is maintaining clean colour mixtures in watercolour. Dirty rinse water contains traces of earlier pigments, so those unwanted pigments can enter a fresh wash and reduce its brightness or clarity. The result may be a dull, muddy colour rather than a clean one. Dirty water cannot purify colours, strengthen paper, or renew a brush. Therefore the practical problem described by option C is the correct answer.

Correct answer: A. One for rinsing brushes and the other for clean water

Explanation: The governing concept is preventing pigment contamination during watercolour work. One container is used to rinse colour from the brush, while the second remains cleaner for diluting paint or making pale washes. Because the rinse water becomes coloured, using it for fresh mixtures can make them dull or muddy. The alternatives assign unrealistic purposes to the containers. Hence option A correctly states the two-container method.

Correct answer: B. The paper stays stable and bends less

Explanation: The governing concept is stabilising the paper during wet painting. Watercolour washes add moisture, which can make a sheet buckle, shift, or form uneven pools. Taping the edges to a firm board holds the paper flatter and keeps the working surface steady while painting. It does not automatically mix colours, enlarge the brush tip, or make paper transparent. Therefore option B is correct.

Correct answer: D. Wet-on-wet

Explanation: The governing concept is wet-on-wet watercolour technique. In this method, moist paint is applied to damp paper or to a still-wet wash, allowing nearby colours to spread and merge gradually. That controlled softness is useful for broad sky areas, clouds, and gentle tonal transitions. Dry brush, black outlines, and cutting paper do not create the same fluid atmospheric effect. Thus option D is the most suitable answer.

Correct answer: A. Apply light colour on damp paper

Explanation: The governing concept is controlling the spread of a watercolour wash. When a light colour is placed on damp paper, moisture lets the pigment move gradually beyond the stroke and form a soft, diffused edge. This resembles the gentle transitions needed for clouds. A thick black line creates a hard edge, while cutting paper or applying oil is unrelated and unsuitable. Therefore option A is correct.

Correct answer: D. Light horizontal lines

Explanation: The governing concept is visual suggestion: water surfaces are commonly indicated by soft, broken horizontal marks, and reflections follow that surface direction. Therefore option D, light horizontal lines, is correct. They should be varied in length and softened so the reflection appears to shimmer rather than look like a rigid grid. Thick vertical lines, round dots, and diagonal black lines do not naturally communicate a calm horizontal water surface.

Correct answer: A. Rough texture

Explanation: The governing concept is that a dry brush carries little water and leaves broken marks across the paper’s tooth. Those irregular marks reveal the surface and are useful for rough textures such as wood, dry grass, or stone, so option A is correct. An even wash needs a wetter, controlled brush, while wetting paper requires clean water. Very soft clouds are usually developed with softer wet techniques rather than a strongly broken dry-brush mark.

Correct answer: B. To create a mottled texture

Explanation: The governing concept is that an absorbent, irregular tool creates broken marks rather than precise lines. Pressing or dabbing a sponge into watercolour produces uneven clusters of pigment, so option B is correct for mottled textures such as foliage, stone, or distant ground. A thin straight line requires a pointed brush or ruler, scissors cut paper, and brush washing needs clean water in a container. The sponge should be tested first to control moisture and pressure.

Correct answer: C. Granular texture

Explanation: The governing concept is experimental watercolour texture. When salt is sprinkled onto a still-wet wash, it can draw moisture and pigment toward the crystals, leaving lighter, grainy or star-like marks as the area dries. Thus option C, granular texture, is correct. Salt cannot create a flat black layer or straight lines, and it does not cut the paper. The salt should be brushed away only after the paint has dried sufficiently.

Correct answer: D. Clean damp brush

Explanation: The governing concept is colour lifting: pigment can be removed or lightened by reactivating it with controlled moisture and absorbing it. A clean, damp brush can pick up some colour from a damp watercolour area, so option D is correct. It should be damp rather than dripping, and it must be rinsed between lifts to avoid spreading pigment. A pencil, scissors, and ruler may serve drawing or cutting purposes but cannot lift a watercolour wash.

Correct answer: A. Some colour may lift and create a lighter area

Explanation: The governing concept is absorbent lifting. Because tissue draws up some of the still-wet pigment, gently pressing it onto the painted area can leave a lighter patch or soft textured mark; therefore option A is correct. The result depends on how wet the paint is and how firmly the tissue is pressed. Rubbing may disturb the paper or spread colour, while the other options describe effects unrelated to pressing tissue on wet paint.

Correct answer: B. The paper surface may become damaged

Explanation: The governing concept is the fragility of wet paper and watercolour layers. Repeated rubbing can disturb the pigment and lift or roughen the paper fibres, so option B, damage to the paper surface, is correct. It may also make the wash muddy or uneven rather than unusually bright. Rubbing cannot enlarge the artwork or turn ordinary watercolour metallic. The safer method is to make deliberate strokes, allow areas to settle, and avoid repeatedly working a wet patch.

Correct answer: C. After light and middle values are established

Explanation: The governing concept is value planning and gradual layering in transparent watercolour. Artists usually establish the light areas first, add middle values, and then build the darkest accents after judging the overall contrast. Therefore option C is correct. Starting with dark paint can make corrections difficult and may overpower the composition; the other choices describe no useful general sequence. Dark passages should still be added in controlled layers rather than one heavy application.

Correct answer: D. Leave that area unpainted

Explanation: The governing concept is that transparent watercolour usually uses the white of the paper to represent the brightest highlights. The artist should identify that area before painting and leave it unpainted. Black or opaque paint would cover the light surface, and repeated wetting cannot restore the paper’s original brightness. Thus, option D preserves the highlight most effectively.

Correct answer: C. Apron

Explanation: The governing safety principle is to cover clothing before beginning practical painting. An apron is worn over the body and catches water, pigment, and accidental splashes, helping prevent stains on ordinary clothes. A woollen or paper cap covers the head rather than the clothing, and metal armour is unnecessary and unsuitable. Thus, option C is the practical protective choice for watercolour work.

Correct answer: D. It may contain substances that are not safe for health

Explanation: The governing concept is safe handling of art materials. Watercolour is manufactured for application to a painting, not for contact with the mouth, and its pigments, binders, or other ingredients may not be safe to swallow. Tasting it cannot enlarge a painting, dry a brush, or thicken paper. Therefore, option D correctly gives the health-related reason, and hands should be washed after painting.

Correct answer: A. The painting must be completely dry

Explanation: The governing preservation principle is to store artwork only after its moisture has evaporated. A completely dry watercolour is less likely to smear, transfer pigment to another surface, or stick to protective paper. Keeping it in water, folding it while damp, or applying oil can damage the paper and alter the paint. Hence option A is correct; afterward, store the work flat in a clean, dry, protected place.

Correct answer: B. Plan and control water and pigment

Explanation: The governing concept is controlled planning in a transparent medium. Before and during painting, the artist should plan the composition, use clean water, and control the amount of pigment and moisture in each wash. This produces deliberate edges, clear colours, and fewer muddy areas. Quickly mixing everything, using dirty water, or rubbing wet paper reduces quality and can damage the surface. Therefore, option B is correct.

Correct answer: A. Brush and paper moisture should be controlled

Explanation: The governing technique is moisture control. Too much water on the brush, paper, or painted area can spread pigment unpredictably and leave blooms or unwanted spots as the wash dries. The artist should use an appropriate water-to-pigment ratio, remove excess water from the brush, and avoid disturbing partly dry areas. Oil, repeated folding, and adding black do not solve the problem. Thus, option A is correct.

Correct answer: A. Thick watercolour paper

Explanation: The governing material principle is that watercolour needs a stable, absorbent surface. Thick watercolour paper can take up water and pigment without tearing easily, and it is less likely to wrinkle severely than thin paper. Newspaper is fragile, while oily paper and plastic resist absorption and make controlled washes difficult. Therefore, option A is the most suitable choice for ordinary watercolour painting.
