Watercolour

Dry-brush texture is created when a brush carrying relatively little water leaves broken marks across the raised areas of a textured sheet. Very smooth paper has fewer raised and recessed points to catch the bristles, so the characteristic broken texture is weaker. Option D is correct. Dark colour, excess water, or brush softness may influence the result, but none explains the role of the paper surface as directly.

Translucency in watercolour is suggested by allowing the brightness of the paper to show through a thin, transparent wash. A restrained soft shadow gives the petal volume without covering its light quality, so option A is correct. A thick opaque layer blocks the paper, and a heavy black outline or uniformly black fill removes the delicate transitions that make a petal appear translucent. Build the effect gradually and preserve the lightest areas.

Colour harmony means that the colours in a composition relate to one another rather than appearing unrelated. Using a limited palette and repeating small amounts of its colours in different areas creates visual connections; changing proportions still provides variety. Thus option A is correct. A new unrelated colour for every object weakens unity, adding black everywhere can make mixtures dull, and full saturation throughout can create visual competition.

The governing concept is controlled diffusion in watercolour. On a wet surface, excess moisture and a large amount of fluid paint allow pigments to travel and merge widely; less moisture and a measured paint load restrict the spread. Therefore, option C is correct. Brush size may influence handling, but it is not the primary control, while paper name and subject do not determine blending.

The governing concept is transparent layering. A glaze should be placed over a completely dry base so that the new wash remains clear and does not disturb or lift the underlying pigment. Thus option A is correct. A soaked sheet or an overloaded brush encourages uncontrolled spreading, and scratching the base damages the surface rather than improving the glaze.

The governing concept is protecting a dry watercolour layer from reactivation. If the base is only partly dry, or if the brush is moved repeatedly over it, water and friction dissolve and lift its pigment. The colours then mix and look muddy, making option B correct. A light base, pure upper colour, or thick paper does not by itself cause this lifting.

The governing concept is transparent glazing and value control. Repeated, thin layers of the same hue increase the darkness gradually while allowing the paper’s light to pass through, so the colour stays luminous. Therefore option C is correct. Heavy black can dull the hue, white reduces transparency, and rubbing harms the paper instead of building a controlled value.

The governing concept is preserving the white of the paper in a transparent medium. Planning the highlight first and leaving that area untouched gives the cleanest, brightest result because light comes from the paper itself. Thus option A is correct. Opaque white may look chalky, rubbing can damage the paper, and removing dark paint is unreliable and disruptive.

The governing concept is lifting while watercolour is still workable. A clean, slightly damp brush can absorb and lift the unwanted wet pigment through gentle touches; blotting the brush between touches prevents adding excess water. Therefore option B is correct. Darker paint hides rather than restores the highlight, scratching damages the paper, and soaking spreads the colour.

The governing concept is pigment migration during drying. Excess water gathers at the boundary of a wash, forming a bead; as that water evaporates, it carries pigment toward the edge and leaves a concentrated dark line. Hence option C is correct. Brush size may affect coverage, but pigment pooling—not paper whiteness or low pigment alone—causes this edge mark.

The governing concept is controlled lifting. A clean, damp brush has enough absorbency to pick up the excess paint bead without introducing a new flood of water or pigment. Therefore option D is correct; the brush should usually be lightly blotted first. A dripping brush spreads the wash, a dry brush lifts poorly, and a paint-loaded brush adds colour.

The governing concept is a backrun, or bloom, caused by uneven drying. When clean water enters a partly drying wash, it moves into the wetter area and pushes pigment outward, leaving a flower-like edge after drying. Thus option A is correct. Dry paint, pencil marks, or a clean brush do not by themselves create this moisture-driven pigment movement.

The governing concept is controlled backrun formation. A drop of clean water is added while the wash is still damp and beginning to dry; the moisture imbalance pushes pigment and creates the characteristic bloom edge. Therefore option B is correct. On a fully dry layer the water generally cannot produce the same spreading, while the other choices describe no suitable timing condition.

The governing concept is dry-brush mark-making: a brush carrying very little water or paint skips across the surface instead of forming a continuous wash. On rough paper, the raised grains catch the pigment while recessed areas may remain white, creating broken, textured marks. Therefore option C is correct. A describes a flowing wash, while B and D are unrelated to paper texture.

Granulation is a watercolour effect produced when particular pigments separate or settle into the paper’s tooth as the wash dries. This creates a visible grain-like or speckled texture, especially on textured paper. Option A correctly identifies the pigment-and-surface relationship. A thick white layer, a damaged brush, and boiling water do not cause granulation, so options B, C, and D are unsuitable.

To minimise granulation, the artist should control both the surface and the pigment. Smooth paper provides fewer grooves in which particles can collect, while a less-granulating pigment produces a more even wash. Thus option B is correct. Rough paper and granulating pigment strengthen the effect; extra black or excessive water does not reliably remove it and may create other problems.

To show the three planes of a cube, the artist must first establish one light direction and then assign values according to how each plane faces that light. Three related but distinct light, middle, and dark values clarify the planes and their spatial orientation, so option B is correct. Equal values flatten the cube, black removes useful variation, and changing only the outline cannot describe surface direction.

The governing concept is observation of reflected light and softened edges. Moving water, ripples, and the changing angle of the surface break the reflected image, so its contours are usually less sharp than those of the object above it. Therefore option A is correct. Options B, C, and D are incorrect: reflections are not always black, the object need not be transparent, and paper does not erase a properly painted reflection. Use broken horizontal strokes and gentler contrast.

The governing concept is visual comparison between an object and its reflection. Reflections in a river are normally affected by ripples and atmosphere, so they use softer edges, weaker detail, and often slightly reduced contrast. Painting one too dark and hard makes it look heavier and more solid than the real object; therefore option B is correct. Option A gives the opposite effect, while C and D do not follow from the painting treatment.

The governing concept is transparency, a defining quality of traditional watercolour. Light tints are usually created by diluting transparent pigment with water and allowing the paper to provide the light. Adding too much opaque white covers the paper and scatters light, producing a dull, chalky appearance; therefore option A is correct. Clean water generally creates a clearer wash, while paper thickness and washing the brush do not directly create chalkiness in the painted tint.

The governing concept is that watercolour changes as it dries. A wet wash may look darker, glossier, or more intense than the final dry passage, so a dry sample gives a reliable reference for hue, value, transparency, and mixing behaviour. Therefore option B is correct. Recording it does not measure brush size, add weight to paper, or make pigment permanent. Including the pigment and water proportions makes the record more useful for later repetition.

The governing concept is reproducibility through a controlled colour record. A colour name alone does not state pigment strength or dilution, but recorded ratios of each colour and water, together with a dry sample, provide both the recipe and the actual finished appearance. Therefore option C is correct. Brush number and paper size may affect application, yet neither records the mixture itself. A dry sample also accounts for the change that occurs during drying.

Paper behaves differently according to its texture, sizing, and absorbency. A small test shows how quickly water and pigment spread, whether the surface blooms, and how much working time is available. Therefore, option A is correct: testing helps the artist adjust water, pigment, and brush movement before risking a large wash. The other options do not describe any real purpose of paper testing.

Highly absorbent paper pulls water and pigment into its fibres quickly. This shortens the time available to move a wash smoothly, so one brush stroke can dry before the next stroke joins it. The resulting overlaps or joins may become visible as bands or uneven patches. Option B is correct; the other choices incorrectly suggest longer wetness, automatic mixing, or increased gloss.

Watercolour paper expands when it becomes wet and can contract as it dries. If it is not secured, this movement may produce buckling, pools of colour, and an uneven working surface. Stretching or firmly attaching the sheet to a board reduces that warping and supports broad wet washes. Option C is correct; stretching does not darken paint, harden a brush, or make transparent colour opaque.
