Question 1

What is achieved by gradually blending one colour into another?

Accepted Answer

Gradual colour transition The governing technique is blending or gradation. By changing the proportion of the two colours gradually and softening the boundary, the artist creates a smooth visual transition rather than a sudden division. Thus option D is correct. A hard edge is the opposite effect, and the remaining choices describe neither the purpose nor the result of controlled blending.

Question 2

Which surface is useful for mixing poster colours?

Accepted Answer

Palette The governing concept is preparing and mixing paint on a suitable working surface. A palette is smooth, washable, and easy to control, so separate colours can be placed and blended without being absorbed. Thus, option D is correct. Cloth absorbs paint, soil is uneven and dirty, and a wooden door is an unsuitable large surface that may contain dust or absorb moisture. A palette also helps the artist use only the required quantity and keep mixtures organized.

Question 3

What is good to do before applying a mixed colour to the main artwork?

Accepted Answer

Test a sample on separate paper The governing concept is testing and controlling a colour mixture before applying it to the final artwork. A small sample on separate paper reveals the mixture’s shade, thickness, coverage, and any noticeable change after drying. Therefore, option B is correct. Applying it directly could spoil a large area if the colour is too dark, pale, thick, or watery; the other choices do not provide a useful check.

Question 4

How should brush strokes be used while filling a large area with poster colour?

Accepted Answer

Even and in one direction The governing concept is uniform brushwork for a flat painted surface. Even strokes moving consistently in one direction distribute the colour more regularly and reduce visible patchiness, making option C correct. Irregular strokes create an uneven texture, heavy pressure may damage the paper or squeeze out excess paint, and circular strokes are not the only suitable method for covering a large flat area. Moderate, controlled movement gives better results.

Question 5

What is necessary for creating an even coloured area?

Accepted Answer

A mixture of even consistency The governing concept is consistency of the paint mixture. When poster colour has an even, workable thickness, each brushload spreads in a similar way and the finished area appears uniform; therefore option A is correct. Changing colour with every stroke prevents unity, a very dry brush can leave gaps and streaks, and folded paper makes the surface uneven. Consistency should be checked before and during application.

Question 6

What should be kept in mind while filling a circular shape with poster colour?

Accepted Answer

Keep the colour even within the boundary The governing concept is controlled, even application of paint. While filling a circular shape, the brush should follow the outline carefully and distribute an appropriate amount of colour inside the boundary. Option B is correct because it gives a neat edge and an even surface. Spreading outside the outline damages the shape, folding the paper can disturb the paint, and pressing too hard may create uneven marks or damage the sheet.

Question 7

How much colour should be taken on the brush while filling with poster colour?

Accepted Answer

A controlled and sufficient amount The governing technique is controlled brush loading. The brush should carry enough poster colour to cover the area smoothly, but not so much that paint runs, drips, or forms an uneven patch. Excess colour can be lightly removed on the palette edge before touching the paper. Thus option A is correct. A dripping load is wasteful, while no colour or dry colour cannot produce an even painted surface.

Question 8

What is useful to do first while filling a circular shape with poster colour?

Accepted Answer

Carefully colour the edge The governing concept is controlled outlining and filling. When painting a circular shape, carefully working around the edge first establishes a clean boundary and prevents the colour from crossing the outline. The remaining interior can then be filled with steady, even strokes from the edge inward. Option A is correct. Making a hole, folding the paper, or drying unused colour does not fill the shape or improve its finish.

Question 9

Which mixture is most suitable for making a clean orange in poster colour?

Accepted Answer

Mix red and yellow on a clean palette The governing colour-theory rule is that red and yellow are primary colours whose mixture produces orange, a secondary colour. Mixing them on a clean palette helps preserve a clear hue; residue from another colour can make the result muddy. Blue and yellow produce green, black and white produce a grey value, and red with green tends to reduce saturation rather than create a clean orange. Therefore, option A is correct.

Question 10

What may happen if a brush is left standing in water for a long time?

Accepted Answer

The bristles may bend The governing concept is proper brush maintenance. When a brush stands in water for a long time, its bristles can press against the container’s bottom or sides and lose their intended shape. This may bend the hairs and spoil the pointed tip. It cannot brighten the colour, thicken paper, or lengthen the handle. Therefore, option B is the only reasonable result.

Question 11

When does a soft blend form between watercolours?

Accepted Answer

When colours meet on a wet surface A soft blend is produced by the wet-on-wet method. When the paper or an existing colour area is still damp, fresh watercolour moves gradually into it and the boundary becomes gentle rather than sharp, so option B is correct. Dry paper tends to preserve harder edges, oil interferes with absorption, and a thick layer does not by itself create a soft transition.

Question 12

Which technique is useful for creating a soft transition from one colour to another in watercolour?

Accepted Answer

Let wet colours meet on a damp surface The governing concept is wet-on-wet blending. On a damp surface, neighbouring watercolour washes remain mobile for a short time, allowing their edges to merge gradually and form a soft transition rather than a hard boundary. The amount of moisture must be controlled so the colours do not flood together. A black dividing line creates a sharp edge, widely separated dry colours cannot blend, and glue is not a normal watercolour medium. Thus, option A is correct.

Question 13

What is useful for creating a soft transition between two watercolours?

Accepted Answer

Blend both colours gradually on a slightly wet surface The governing technique is controlled wet-on-wet blending. On a slightly damp surface, water allows the edges of neighbouring pigments to move and merge gradually, producing a soft transition rather than a sharp boundary. Therefore, option A is correct. A black line creates separation, completely dry paper usually preserves a hard edge, and sand is not a normal blending material for watercolour. The brush still needs controlled moisture to prevent uncontrolled spreading.

Question 14

What result is obtained when two colours are mixed on a wet watercolour surface?

Accepted Answer

A soft colour transition The governing concept is the wet-on-wet watercolour technique. Because the paper is damp, two still-wet pigments spread slightly and merge gradually, producing a soft transition without a sharp boundary. Therefore option B is correct. A hard black boundary would require a strong dry edge or outlining, while metallic effect and dry texture are unrelated results. The amount of water must still be controlled to avoid unwanted spreading.

Question 15

What problem may occur if a watercolour brush is left standing in water for a long time?

Accepted Answer

The bristles may bend The governing concept is proper care of painting tools. If a brush is left standing in water, prolonged moisture can soften or deform the bristles, and water may also weaken the adhesive or fitting that holds them. Option B is correct because bent bristles lose their intended shape and make controlled marks difficult. The brush cannot brighten paint, strengthen paper, or make the water thick. It should be rinsed and stored with the bristles supported.

Question 16

What is useful before filling letters with acrylic colour?

Accepted Answer

Make a light pencil outline The governing concept is planning and maintaining accurate lettering. A light pencil outline establishes the letter height, shape, alignment, and spacing before opaque acrylic paint is applied. It can be adjusted gently and usually becomes covered by the final colour. Dipping the paper may damage or warp it, adding oil is unsuitable for acrylic paint, and cutting the brush reduces its usefulness. Hence, option A is correct.

Question 17

Which brush is useful for filling a large area with acrylic colour?

Accepted Answer

Broad flat brush The governing tool-selection principle is to match brush shape and size to the area being painted. A broad flat brush carries enough paint and covers a wide region with fewer, more even strokes, so option C is correct. A very thin brush is better for lines and details, a wire brush is not a normal paintbrush for smooth coverage, and a brush without bristles cannot apply paint effectively.

Question 18

How should brush strokes be used while filling a flat area with acrylic colour?

Accepted Answer

Even and controlled The governing technique for filling a flat area is controlled, even application. Brush strokes should be reasonably uniform and should overlap slightly so that the colour forms a continuous layer without obvious gaps, streaks, or patches. Heavy pressure can leave unwanted marks, while irregular or exclusively circular strokes do not ensure an even surface. Thus option A is the most suitable answer.

Question 19

What should be kept in mind while filling a circular shape with acrylic colour?

Accepted Answer

Apply an even colour within the boundary The governing concept is controlled colour filling. Acrylic paint should be distributed evenly inside the drawn boundary so the circular form has a clean outline, consistent coverage, and a neat appearance. Therefore, option C is correct. Spreading beyond the boundary damages the shape, excessive water can reduce body and control, and pressing too hard may roughen the surface or create uneven marks. Short, controlled strokes help near the edge.

Question 20

How much paint is taken on the brush to create a dry-brush effect with acrylic colour?

Accepted Answer

Very little paint Dry-brush is a brush technique in which the brush carries very little, relatively thick paint and is moved lightly across the surface. Because there is little moisture and pigment, the bristles leave broken, scratchy, or textured marks instead of a smooth solid layer. Very watery paint would produce a different wash effect, while a full container and glue are unsuitable. Thus, option B is correct.

Question 21

What effect can be obtained by applying acrylic colour with a sponge?

Accepted Answer

Speckled texture Using a sponge is a surface-application brush technique that transfers paint through many small, irregular contact points. This can produce a speckled, stippled, mottled, or uneven texture, useful for backgrounds and natural surfaces. It is not limited to making a straight line or handwriting, and it cannot create actual metal engraving. Therefore, option C accurately identifies the effect.

Question 22

What is a gradual transition from dark to light in acrylic colour called?

Accepted Answer

Gradation Gradation is the controlled and gradual change of colour, tone or value from one degree to another, such as moving from dark to light without a harsh boundary. Therefore option B is correct. Printing transfers an image, scratching removes or marks a surface, and drawing creates lines or forms; none of these terms specifically names a smooth tonal transition in paint.

Question 23

What is a common way to lighten an acrylic colour?

Accepted Answer

Add white colour The governing concept is colour value and tinting. Adding white to an acrylic colour raises its value and creates a tint, making the colour appear lighter while retaining a related hue. Black does the opposite by creating a shade, and a complementary colour generally dulls or neutralises the mixture rather than simply lightening it. Varnish may change surface sheen or transparency but is not the standard colour-lightening method. Therefore option D is correct.

Question 24

Why is reshaping an acrylic brush after washing useful?

Accepted Answer

To maintain the brush’s original shape and control over strokes The governing concept is brush maintenance and control of the working tip. After washing, gently reshaping the damp bristles helps them dry in their intended form instead of splaying or bending. A well-shaped tip produces cleaner lines, edges, and controlled strokes during the next use. This action does not dry paint, waterproof the handle, or make bristles harder; excessive stiffness can reduce control. Hence option A is correct.

Question 25

What is the process of gradually merging two colours called?

Accepted Answer

Blending The governing concept is colour transition. Blending means gradually merging adjacent colours so that the boundary changes smoothly rather than appearing as a hard, sudden edge. When one colour is worked into the next with controlled brush movement, intermediate tones may appear, making option B correct. Printing transfers an image, cutting removes material, and outlining draws a boundary; none describes gradual colour merging.
