Watercolour

Correct answer: B. Repeatedly rubbing with a wet brush

Explanation: The governing concept is reactivation of water-soluble watercolour. A dry layer can become wet again when a loaded brush repeatedly passes over it, and the mechanical rubbing then lifts the underlying pigment. Thus option B is correct. A few decisive strokes reduce disturbance, transparency alone does not lift the layer, and thick paper normally gives the surface greater stability rather than causing pigment removal.

Correct answer: B. Value and edge contrast

Explanation: The governing concept is figure-ground separation through value and edge contrast. Two hues can be different but still have similar lightness, so the figure may merge visually with its background. Checking and strengthening the value difference, while sharpening selected edges, improves clarity; therefore option B is correct. Paper texture, brush length, and water temperature do not directly establish the figure’s visual separation.

Correct answer: B. Wait until the surface sheen reduces slightly

Explanation: Watercolour spreading depends on the moisture of the paper. A very glossy surface contains excess water, so the pigment travels rapidly and unpredictably. Waiting until the visible sheen reduces slightly leaves the paper damp rather than flooded; the colour can then spread softly but remain controllable. Adding water or loading more water into the brush increases spreading, while sharply tilting the paper makes the flow less predictable. Therefore, option B is correct.

Correct answer: B. Gently lift the excess paint with a clean, damp brush

Explanation: A dark bead at the lower edge of a wash is a pool of excess water and pigment. If it dries in place, evaporation leaves a hard, dark tide mark that disrupts the even wash. A clean, damp brush can absorb or lift the surplus gently without adding another colour. Letting it dry preserves the defect, black paint worsens it, and turning the paper may disturb the whole wash. Thus option B is the correct treatment.

Correct answer: A. Glazing

Explanation: Glazing means placing a thin, transparent wash over a previous transparent layer only after the first layer has dried. Light passes through the upper wash and interacts visually with the colour below, producing greater depth without making the surface opaque. Wet-on-wet requires a wet underlying surface, dry brush emphasizes broken texture, and lifting removes pigment. Because the question specifies a dry transparent layer, option A is unambiguous.

Correct answer: B. Use stronger value contrast and sharper edges in the foreground

Explanation: Warm foreground and cool background colours can suggest distance, but they are not sufficient by themselves. Stronger light-dark value contrast and sharper, clearer edges make nearer forms appear more definite and spatially important. Adding detail to the background may bring it forward, while equal values flatten the scene. Making the foreground much lighter is not a dependable correction. Therefore, option B best strengthens depth.

Correct answer: B. The masking was removed forcefully from damp or weak paper

Explanation: Masking fluid should be removed gently only when the painted area and paper are fully dry, and the paper should have enough strength to tolerate rubbing or peeling. Pulling it forcefully from a damp or weak sheet can lift paper fibres along with the dried masking film, causing tearing or surface loss. Fully dry paper, thin application, or mounting alone does not normally explain the damage. Hence option B is correct.

Correct answer: A. After it dries, gently soften the edge with a clean damp brush

Explanation: A hard band is a sharp, unwanted boundary left when a wash dries unevenly. After the area is dry, a clean brush carrying controlled, limited moisture can gently re-wet the edge and soften the transition. The brush must not be saturated, because excess water may create another bloom or tide mark. Black paint hides rather than corrects the problem, scrubbing damages paper, and flooding the whole sky destroys control. Thus option A is best.

Correct answer: B. Excessive layers making the colour muddy

Explanation: Watercolour gains luminosity when light can pass through relatively clear washes and reflect from the paper. Applying too many glazes increases the amount of pigment and overlapping colour, reducing light reflection and visual clarity. The result may become dull, heavy, or muddy. Drying each layer is necessary for glazing, not the cause of lost brightness; mounting paper and using a clean brush also do not create this effect. Therefore, option B is correct.

Correct answer: B. Add the dark colour gradually to the light mixture

Explanation: Dark pigments often have strong tinting power, so a small quantity can noticeably lower the value of a light mixture. To retain control, first prepare the desired light colour with water, then add the dark pigment in tiny increments, testing after each addition. Adding all the light colour to a dark mixture may waste paint and still produce an uneven result. Equal quantities or black first do not reliably create the intended light tone. Option B is correct.

Correct answer: A. Excess clean water pushed the pigment toward the edge

Explanation: This is a watercolour back-run, also called a bloom. When excess clean water enters a darker wash that is still damp, the new water moves outward and pushes suspended pigment toward its drying boundary. The pigment collects there, producing a noticeable light-looking or bright rim. Paper absorption alone does not create this movement, and no white paint or dry-brush scraping is involved. Thus option A is correct.

Correct answer: A. Add darker, controlled details to the centre after it dries

Explanation: A focal point is strengthened through contrast in value, detail, and edge sharpness. Once the flower is dry, adding a few darker, controlled marks in the centre creates a clearer edge and stronger tonal contrast against the softer petals. Rewetting the petals or the whole flower can spread pigment and increase blur. Lifting colour would reduce the centre’s value contrast rather than clarify it. Hence option A is correct.

Correct answer: A. The background has more detail and intense colour

Explanation: Visual hierarchy is controlled by the combined distribution of contrast, detail, colour intensity, and edge sharpness. Even if the figure has strong contrast, a background packed with detail, intense colour, and hard edges can compete with it and attract attention first. A simpler, lighter, softer-edged background near the focal area would restore emphasis. Sharper figure edges and surrounding space generally support focus, so option A is correct.

Correct answer: B. Increase water gradually and remove excess liquid from the brush

Explanation: A graded wash requires a controlled, gradual change in value or dilution. Increase the water step by step rather than flooding the final area, and keep the brush damp rather than overloaded by removing excess liquid on the palette edge or tissue. Too much liquid creates blooms or back-runs as it moves into a damp wash. Wetting the paper more or adding drops increases the risk, so option B is correct.

Correct answer: A. Mix a complementary or related dark colour into the base hue

Explanation: A convincing shadow usually remains related to the object’s local colour and the surrounding colour scheme. Mixing the base hue with a complementary or neighbouring dark produces a chromatic, integrated shadow with depth, rather than an isolated black patch. Pure black can look flat and disconnected; white makes the mixture lighter and more opaque, while clean water contains no pigment. Therefore, option A is the better method.

Correct answer: A. The damp brush contained too much water

Explanation: The governing concept is water control in a watercolour edge. To soften an edge, the brush should be damp rather than loaded with free water. If it is too wet, it deposits extra moisture that carries pigment outward, so the colour spreads beyond the intended boundary. A completely dry layer normally will not spread by itself, and insufficient pigment makes a mark weak rather than causing excessive flow. Blotting the brush before use prevents this mistake.

Correct answer: A. Consistency of brush load and paint dilution

Explanation: The governing concept is consistency of paint load and dilution. A brush holding more pigment or a thicker mixture produces a darker line, while a brush with less pigment or more water produces a lighter line. Therefore, repeated dark-light variation usually shows that the brush was not reloaded consistently. Even paper wetness can affect spreading, and equal spacing or brush angle affects placement and shape, but none is the main control responsible for value changes in these parallel strokes.

Correct answer: A. The surface was excessively wet

Explanation: The governing technique is the salt texture effect in a watercolour wash. Salt should be sprinkled when the painted surface is damp enough for the crystals to draw moisture and pigment, but not so wet that they simply dissolve. On an excessively wet wash, water surrounds the salt and prevents a clear crystal pattern from forming. A slightly damp surface is generally more suitable, while dry paint gives little opportunity for the salt to move moisture and pigment.

Correct answer: A. Fresh water entering a partly dry wash

Explanation: The governing concept is a backrun, also called a bloom. When fresh water is introduced into a wash that is partly dry, the new moisture moves into the drying paint and pushes pigment toward an irregular boundary. The result is a flower-like mark. Concentrated pigment may make the mark darker, but it does not create the bloom without uneven moisture. Stretching paper and using a pointed brush do not explain this spreading pattern. A controlled damp brush is safer for lifting colour.

Correct answer: B. They will appear unintentionally closer and harsher

Explanation: The governing concept is atmospheric perspective. Distant forms are usually represented with lighter values, reduced contrast, less detail, and softer edges because air and distance weaken their visual intensity. A dark black outline does the opposite: it creates a sharp, high-contrast boundary, making the mountains appear unnaturally close and harsh. It will not make them disappear or automatically lighten their colour. Soft, less-defined edges and restrained contrast would better communicate distance in a watercolour landscape.

Correct answer: B. Soften some shadow edges according to the form and light

Explanation: The governing concept is varied edge control for showing form. On a rounded object, light changes gradually across turning surfaces, so every shadow boundary should not be equally sharp. Softening selected edges according to the direction and strength of the light creates a gradual transition and suggests volume. Removing the shadow removes form, outlining everything makes the object harsher, and a flat wash eliminates the value changes needed to show roundness. Natural painting uses a deliberate mixture of soft and firm edges.

Correct answer: B. Paint a test swatch on the same paper and let it dry completely

Explanation: The governing concept is the drying shift of transparent watercolour. While wet, water makes the mixture look darker and more saturated; after evaporation, the pigment settles into the paper and the visible value often becomes lighter. The reliable check is to paint a small swatch on the same paper and let it dry completely before judging or adjusting the mixture. Looking only at a wet palette is misleading, adding black changes the colour character, and folding the paper has no useful role in predicting the final value.

Correct answer: A. Brush pressure increased midway

Explanation: The governing concept is pressure control in a brushstroke. A fine branch is made with the pointed tip and light, even pressure. If pressure increases midway, the bristles spread and release a wider mark, producing the observed change in width. Excess water or paint can cause general spreading, so it is a possible secondary problem, but a local widening that occurs exactly midway most directly indicates a pressure change. A rough surface may interrupt a line, and a dry layer cannot explain this fresh broadening.

Correct answer: A. Placement, edge quality and detail also matter along with value

Explanation: The governing concept is visual hierarchy: a focal point is created by a coordinated group of visual cues rather than darkness alone. Value contrast can attract attention, but placement, sharper or more controlled edges, selective detail, colour contrast, and surrounding quiet areas also guide the viewer’s eye. A dark mark in an unimportant position may fail to dominate, while excessive dark marks everywhere remove emphasis. Dark colour is not always transparent, and both suitable paper and brushes can handle it.

Correct answer: A. Paint may run too quickly and pool at the bottom

Explanation: The governing concept is gravity-controlled wash flow. A slight tilt helps a watercolour wash move in a predictable direction, but an excessively steep angle increases the downward component of gravity. The liquid paint then runs too quickly, gathers at the lower edge, and may form an uneven darker pool or drip. Tilting does not make the colour dry immediately, harden the paper, or turn transparent watercolour opaque. The painter should use a small, controlled angle and adjust the brush load to maintain an even wash.
