Poster colour

The governing concept is maintaining control of the painting surface. Paper kept stable and flat allows the hand and brush to move evenly, supports accurate edges, and reduces accidental folds, spills, and uneven marks. Thus option A is correct. Hanging, folding, or dipping the paper makes controlled application difficult and can distort the surface or damage the artwork.

The governing concept is uniform application of paint. A consistent mixture supplies similar pigment across the surface, while regular, overlapping strokes reduce gaps, streaks, and visible changes in thickness. Therefore, option A is correct. Different thicknesses create an uneven background, a dry broken brush leaves rough marks, and excessive water can cause pale areas, runs, or patchy coverage.

The governing concept is controlled colour mixing. Taking small amounts of both poster colours first allows the artist to test their proportion, observe the resulting shade and adjust it gradually. It also prevents unnecessary waste if the mixture is too dark, too light or otherwise unsuitable. More colour can be added later, whereas an excessive mixture is difficult to correct. Therefore, option A is correct; the other choices are wasteful, unrelated or technically unsound.

The governing concept is the opacity of poster colour. A sufficiently thick dark layer reflects and blocks much of the light, so it can hide or cover a lighter layer beneath it, especially after the first layer has dried. This is why artists often paint broad dark shapes over lighter areas during layering. Option A is correct. The other choices describe effects that do not follow from applying a darker opaque paint layer.

The governing concept is orderly layering. The first coat should be completely dry before a second coat is brushed over it, because a wet lower coat can dissolve, smear or mix with the new colour. Waiting also helps the second layer retain a clean edge and an even surface. Thus option A is correct. A wet layer risks muddy marks, while removing the layer or covering it with sand is not a normal poster-colour technique.

The governing concept is the visual quality of opaque poster colour. It produces strong, relatively even areas of colour and can define clear boundaries, so it is especially effective for bold, flat shapes in illustrations, designs and posters. A light preliminary sketch helps the artist keep those boundaries neat. Option A is correct. Invisible shapes, sculptures and thread forms are not the ordinary two-dimensional uses described by this medium.

The governing concept is preliminary sketching before painting. A pencil, used with light pressure, creates a controllable outline that guides the placement of poster colour without dominating the finished image. The artist can adjust or erase it before or during colouring. Option A is correct. Charcoal and marker usually make darker or broader marks, while a paintbrush is designed to apply colour rather than make a fine, faint guide line.

The governing concept is brush control. A suitable brush held steadily, combined with slow and deliberate strokes, keeps paint within the intended boundary and produces a clean edge. Using moderate paint and working from the edge inward can further reduce accidental spreading. Option A is correct. Too much water makes the paint run, a dirty palette contaminates colours, and torn paper cannot improve edge control.

The governing concept is maintaining clean tools and usable paint consistency. Water is kept nearby to rinse colour from the brush before changing shades and, when appropriate, to thin a paint that is too thick. Clean water helps prevent unwanted colour contamination, while a separate cloth can remove excess moisture. Option A is correct; water is not kept for dipping the paper, drying paint or damaging the palette.

The governing concept is proper storage of water-based poster colour. Direct sunlight and exposure to open air can warm the paint and allow moisture to evaporate, causing the colour to become dry, thick or difficult to use. Keeping containers closed and in a cool, shaded place helps preserve their workable consistency. Option A is correct. The other choices describe changes that are not expected from sunlight exposure in this situation.

The governing concept is protective practice during art-making. Poster colour can accidentally splash or transfer from wet hands, brushes and palettes onto clothing. An apron forms a washable protective layer, helping keep ordinary clothes cleaner while the artist works. Option A is correct. An apron does not change the drying speed of paint, sharpen a brush tip or increase the thickness of paper. It protects the wearer and supports a cleaner workspace.

The governing concept is proper brush care. After poster-colour work, wash the brush with suitable clean water so that paint does not dry between the bristles. Then gently reshape the bristles and store the brush safely, preferably with the bristles protected. This is why option A is correct. Leaving it in paint can harden the hairs, while breaking or burning it destroys a useful tool.

The governing concept is colour testing before final application. A small stroke on separate paper reveals the colour’s tone, thickness, opacity, and consistency under the available water and paint mixture. This allows the artist to adjust the mixture without damaging the artwork, so option A is correct. Testing in the finished picture risks stains, while clothes and the floor are unsuitable working surfaces.

The governing painting principle is to build colour from lighter areas toward darker ones. A light base leaves room for darker poster colour to cover small gaps, strengthen outlines, and correct uneven edges after the first layer dries. Therefore option A is correct. The other choices describe harmful or unrelated results: painting order does not tear paper, prevent drying, or make a brush hard.

The governing design concept is visual emphasis through contrast. Bright colours attract the eye, and contrasting colours help the main heading, symbol, or image stand apart from its background. Thus option A is correct, provided the colours are used in a balanced way rather than everywhere. Grey alone, tiny unclear lettering, or one pale colour usually creates less visual emphasis and weakens the poster’s message.

The governing studio-practice concept is responsible care of materials and workspace. After painting, the artist should close colour containers, wash and dry brushes appropriately, dispose of dirty water safely, and return tools to their places. Therefore option A is correct. Leaving colours open causes drying, keeping brushes in paint damages their shape, and spilling dirty water creates an untidy and unsafe area.

Successful poster painting depends on controlling paint quantity, water, brush movement, edges, and layering; these skills improve through regular, planned practice. Option A is therefore correct. Random spreading produces weak shapes, excessive water makes colour thin or uneven, and a dirty brush contaminates mixtures and marks. Small exercises such as lines, flat fills, dots, and simple shapes build reliable control before a final artwork.

The governing technique is controlled layering. When the first poster-colour layer is light or uneven, allow it to dry fully and then apply a second thin, even coat. The new layer increases coverage and opacity without disturbing the surface, so option B is correct. Rubbing a wet layer can lift paint or damage paper; extra water makes coverage weaker, and folding the paper does not correct the colour.

The governing concept is maintaining colour purity during mixing. Residual paint on a palette knife or brush can enter the next mixture and change its hue, brightness, or value, making the result muddy or different from the intended colour. Therefore option D is correct. Cleaning does not dry paint faster, thicken water, or enlarge the palette; it prevents unwanted contamination and gives predictable mixtures.

The governing concept is controlled correction in opaque poster colour. Letting the painted area dry prevents the fresh layer from smearing or lifting the underlying colour. A small, clean brush then allows a precise touch-up along the boundary, so option B is correct. Spreading wet paint with a finger is uncontrolled, pouring water can damage the surface, and a thick black line may change the intended design rather than correct it.

A colour scheme is a planned selection and relationship of colours used in an artwork. Choosing it before painting helps the artist maintain harmony, contrast, emphasis and visual balance throughout the composition, making option C correct. It does not clean the brush, alter the thickness of the paper or make poster colours dry instantly; those effects are unrelated to planning colour relationships.

The governing concept is colour harmony and balance in a planned composition. Selecting a limited, suitable palette in advance helps distribute light and dark, warm and cool, or contrasting colours intentionally, so option A is correct. Planning colours cannot enlarge the paper, increase the number of brushes or prevent paint from drying; those choices affect appearance, not the physical materials or drying process.

The governing concept is avoiding overworking a wet painted surface. Repeated brushing disturbs the drying film, moves pigment unevenly and may roughen or abrade the paper, especially when it becomes wet. Thus option A is correct. Paper cannot turn into metal, colour does not automatically become white, and brushing the same area cannot lengthen the brush; these distractors are unrelated to surface handling.

The governing concept is preventing unintended mixing between adjacent opaque colour areas. Allowing the first colour to dry creates a stable boundary before the neighbouring colour is applied, so option A is correct. Mixing both colours while wet removes separation, excess water can cause bleeding and weak coverage, and shaking the paper does not create a clean edge. Careful brush loading and a dry surface improve the result further.

The governing concept is organised identification and safe handling of art materials. A readable name or visible colour mark lets the artist select the intended container quickly and avoid confusing similar shades, making option A correct. A label does not add meaningful weight, keep paint permanently wet or sharpen a brush. Proper identification also supports orderly storage and reduces accidental colour contamination during work.
