Acrylic colour

Correct answer: D. On separate paper

Explanation: The governing concept is safe testing and practice before applying paint to the final surface. A small sample on separate paper allows the artist to check the colour, opacity, consistency, and brush mark without risking the main composition. Therefore option D is correct. Clothes, a wall, and a brush box are unsuitable surfaces because they may be stained or damaged and do not represent the final work reliably.

Correct answer: A. To wash brushes

Explanation: The governing concept is basic painting-material care. A water container is used to rinse paint from brushes, especially before changing colours or when a different brush mark is needed. This makes option A correct. It is not a tool for cutting canvas, drying the painting, or heating acrylic paint. The water should be changed when very dirty, and brushes should not be left submerged for long periods.

Correct answer: C. Clean the wet paint immediately with water

Explanation: The governing concept is prompt care of painting materials and clothing. Wet acrylic paint is generally easier to remove than dried paint, so the spill should be dealt with immediately by gently rinsing or blotting with water, while following the garment-care instructions. Thus option C is correct. Leaving it allows the paint to set; wax and heat are not appropriate first responses and may make cleaning harder.

Correct answer: D. The painting is completely dry

Explanation: The governing concept is surface preparation and protection. Acrylic paint must be completely dry before varnish is applied, because varnishing a wet layer can trap moisture, disturb the paint film, or produce an uneven finish. Therefore, option D is correct. A wet, folded, or dusty painting is not ready: moisture affects adhesion, folding can damage the surface, and dust becomes sealed under the varnish.

Correct answer: A. A cool and dry place

Explanation: The governing concept is proper storage of art materials. Acrylic colours should be kept in a cool, dry place with their containers closed, away from direct sunlight, excessive heat, and moisture. Thus, option A is correct. Strong sunlight and a hot stove may damage or dry the material, while storing it in a bucket of water is unsuitable and may contaminate the container.

Correct answer: B. Colour balance, clean edges, and required details

Explanation: The governing concept is final visual evaluation. A completed acrylic painting should be reviewed for balanced colours, clean edges, consistent coverage, and the presence of important details. Option B is correct because it checks the qualities that affect the finished image. Paper price, brush length, and water colour do not by themselves show whether the artwork is visually complete or technically neat.

Correct answer: A. The brush bristles may spread

Explanation: The governing concept is brush control and pressure. Pressing a brush too hard bends and spreads its bristles, often producing a broad, uneven, or less controlled stroke and possibly wearing the brush. Therefore, option A is correct. Acrylic paint does not vanish instantly, canvas does not become transparent, and pressure on a brush cannot make water solid.

Correct answer: B. Spread the paint in a consistent direction

Explanation: The governing concept is uniform paint application. To create an even, flat acrylic colour, apply a sufficient amount of paint with steady pressure and strokes moving consistently in one direction; overlap strokes gently before the layer dries. Option B is correct. Changing colour each time, adding dust, or using a dry brush would create visible variation rather than a smooth, continuous layer.

Correct answer: C. By applying the correct colour over it after it dries

Explanation: The governing concept is correction through layering, one advantage of acrylic paint. After the unwanted dark line and its surrounding layer have dried, apply an opaque matching colour over the line with a suitable brush, then restore any needed detail. Option C is correct. Tearing, soaking, or covering the entire painting would damage the work and is unnecessary for a small mistake.

Correct answer: D. To reduce paint wastage

Explanation: The governing concept is economical use of materials. Acrylic paint dries relatively quickly when exposed to air, so putting only a small amount on the palette at first reduces unnecessary waste. More can be added as the work requires, and the unused paint can be kept from drying. Therefore, option D is correct; the other choices do not follow from dispensing a smaller quantity.

Correct answer: A. To understand shapes, colours, and details

Explanation: The governing concept is observation from a visual reference. A reference image helps the artist study proportions, shapes, colour relationships, lighting, textures, and small details before or during painting. Thus, option A is correct. It does not dry paint, cut the canvas, or serve as a brush holder. The artist can use the reference for study while still developing an original composition.

Correct answer: C. Canvas, paper and wood

Explanation: Acrylic colour is a versatile, water-based medium that can adhere to many clean, dry and suitably prepared surfaces. Canvas, paper and wood are common supports, so option C is correct. Glass or metal may also be used when properly cleaned and primed, which makes the word “only” in options A and B incorrect. Wet clay is unstable and is not the general answer.

Correct answer: C. A tint of the colour is formed

Explanation: In colour theory, a tint is made by mixing a hue with white. The addition of white raises the colour value, so the original acrylic colour appears lighter while its basic hue remains recognisable. Option C is correct. Darkening is associated with adding a darker pigment or, cautiously, black; white does not automatically make a colour muddy or erase it. The amount of white controls how pale the resulting tint becomes.

Correct answer: D. Olive or muddy

Explanation: The governing concept is subtractive colour mixing and control of value and saturation. Yellow mixed with a large amount of black loses brightness and purity, so it may become olive, dull, or muddy. Therefore, option D is correct. Pink would require red or magenta, orange requires red, and black cannot turn yellow into pure blue. Black should be added gradually and sparingly.

Correct answer: A. Add a little yellow to white

Explanation: The governing concept is making a tint by adding a small quantity of a stronger colour to white. Cream is a warm, light off-white, so a little yellow mixed into white acrylic produces the most suitable result. Option A is therefore correct. Blue gives a cool bluish tint, red gives pink, and green gives a pale green tint. The yellow should be added gradually to avoid making the mixture bright yellow.

Correct answer: B. By mixing white into orange

Explanation: The governing concept is tinting: adding white to a hue increases its lightness while retaining the hue family. Orange lightened with white produces a soft peach-like colour, so option B is correct. Blue plus white creates a pale blue, green plus black creates a dark green, and yellow mixed with violet tends toward a dull neutral or brownish colour because they are complementary colours. Add white gradually for control.

Correct answer: A. Apply the paint over black and white stripes

Explanation: Transparency describes how much the underlying surface remains visible through a paint layer, while opacity describes how fully it is covered. Applying a consistent swatch across alternating black and white stripes makes this easy to observe: a transparent colour lets both stripes influence the appearance, whereas an opaque one hides them. Thus option A is correct; water observation, container weight and brush length do not measure coverage.

Correct answer: A. Covering the lower layer to create solid forms

Explanation: The governing concept is opacity: an opaque acrylic layer reflects enough light and contains enough pigment to hide much of the colour or drawing beneath it. It is therefore useful for building solid shapes, correcting areas and placing clear highlights over lower layers, making option A correct. Transparent glazes require a thin, diluted or transparent mixture, while soaking paper and cleaning brushes are preparation or maintenance actions, not uses of opaque paint.

Correct answer: B. Large heavy patches and lost texture

Explanation: The governing concept is control of paint load during sponge application. When a sponge carries excess acrylic, separate small impressions can join together, producing large, heavy patches that hide the intended texture. The correct remedy is to remove surplus paint on a test surface before touching the artwork. Excess paint does not create a finer texture, automatically smooth the surface, or necessarily make the colour transparent. Thus, option B is correct.

Correct answer: A. Apply a moderate thin layer without pushing paint toward the tape

Explanation: The governing concept is controlled paint application at a masked boundary. A thick ridge forms when too much acrylic is deposited beside the tape or pushed against its edge. Applying a moderate, even layer and keeping the brush movement controlled prevents excess paint from accumulating. Adding more paint would worsen the ridge, while sand changes texture and wetting the tape weakens the boundary. Hence, option A is the correct practical method.

Correct answer: D. Irregular speckled and cloud-like texture

Explanation: A sponge has an uneven porous surface, so dabbing it into acrylic transfers broken, irregular marks rather than a precise continuous line. By varying pressure, paint load, and direction, the artist can create speckles, soft clouds, foliage-like texture, or mottled surfaces. Fine lettering and mirror reflections need controlled tools and careful drawing. Thus option D is the most suitable effect.

Correct answer: A. The normally recognized basic colour of an object

Explanation: Local colour is the customary colour associated with an object when it is considered without changes caused by dramatic lighting, reflections, or atmospheric effects. For example, a leaf may be described as green even though its observed shade changes in shadow. Option A is correct because it gives the object’s normally recognized basic colour. The background, varnish, and brush handle are unrelated distractors.

Correct answer: B. Formation of a water-resistant layer after drying

Explanation: Acrylic paint is water-based when wet, but its binder forms a stable, water-resistant film as it dries. Because the dried layer does not readily dissolve when the next wet layer is brushed over it, the artist can build colour without reactivating the underpainting. Thus option B is correct. Dried acrylic does not become permanently sticky, automatically glossy, or water-soluble again.

Correct answer: D. The lower layer remains intact without dissolving

Explanation: Acrylic paint forms a relatively durable, water-resistant film as it dries. Once dry, a carefully applied new layer can cover, modify, or detail the surface without normally re dissolving the layer beneath. Therefore option D is correct and this property supports controlled layering. The lower layer does not fully dissolve, the new colour is not automatically transparent, and drying remains possible.

Correct answer: B. Stippling

Explanation: The governing technique is stippling, in which an artist builds tone, colour variation, and surface texture with separate small dots or repeated dabs. The spacing and density of the marks can make an area appear lighter, darker, or more textured, so option B is correct. Graffito involves scratching into a layer, glazing uses transparent layers, and frottage transfers a rubbed texture from another surface; none is defined by dot-making.
