Watercolour

Correct answer: A. To show bright highlights and the light of the paper

Explanation: A key watercolour principle is that white highlights are often created by leaving the paper unpainted rather than covering it with white pigment. Preserved areas can represent reflected light, shine, or bright clouds and flowers. Therefore option A is correct. The other choices concern smell, an impossible colour change, or loss of form and have no relation to the technique.

Correct answer: A. To show bright highlights and the paper’s natural brightness

Explanation: The governing watercolour principle is to use the paper’s white surface as the lightest value. Because watercolour is often transparent and white paint may be used sparingly, an artist plans bright highlights and leaves those areas unpainted. Option A is correct. Saving white does not make colours black, completely prevent spreading, or remove light-dark contrast; those are unrelated effects.

Correct answer: A. The colour layer may appear weak and light

Explanation: The governing concept is control of paint consistency and pigment concentration. Water dilutes the pigment, spreads the paint more thinly, and can make the dried layer look weaker, paler, or less saturated. It does not transform a secondary colour into a primary colour, automatically produce black, or alter the fixed order of hues on a colour wheel. Water should therefore be added gradually while the mixture is observed on a test surface. Option A correctly describes the likely effect.

Correct answer: B. The layer may become weak and transparent

Explanation: The governing concept is control of water-to-pigment ratio in watercolour or diluted paint. Excess water spreads and dilutes the pigment, so the secondary-colour layer may become paler, weaker, and more transparent. It does not change the colour category from secondary to primary, and it does not automatically increase complementary contrast or saturation. For that reason, option B gives the most accurate effect.

Correct answer: D. Add more water

Explanation: The governing concept is watercolour transparency. Unlike opaque media, watercolour becomes lighter mainly when more water is added, allowing the white paper to show through the pigment. Begin with a controlled amount of water and test the wash, because excessive water can cause blooms, weak colour, or buckling on ordinary paper. Black darkens a mixture, thick paint increases opacity, and oil is not a suitable watercolour additive. Therefore, option D is correct.

Correct answer: A. Apply thin layers of colour

Explanation: The governing principle of transparent watercolour is allowing light to pass through the pigment and reflect from the paper. Applying a thin, sufficiently diluted layer preserves this luminous effect, so option A is correct. Thick paint, heavy black, or poster white adds opacity and can cover the paper’s reflective surface, making the mixture look duller and less transparent.

Correct answer: A. Add more water

Explanation: Transparent watercolour depends on the amount of water and the whiteness of the paper rather than on thick white pigment. Adding more clean water spreads the pigment more thinly, so the colour becomes lighter and remains transparent. Thus option A is correct. Black would darken the mixture, thick white would reduce transparency, and rubbing dry pigment is not the normal method for lightening a wet watercolour wash. Excess water should still be controlled.

Correct answer: D. The colour will become very light and transparent

Explanation: The governing concept is dilution in transparent watercolour. Adding excess water spreads and dilutes the pigment, lowering the concentration of colour on the paper. The result is usually a paler, more transparent wash, so option D is correct. More water does not make watercolour oily or generally more opaque; a darker result normally requires a stronger pigment mixture or a further layer after the first layer dries.

Correct answer: D. Dry a test sample before judging the final value

Explanation: The governing concept is the drying shift of transparent watercolour. Wet paint can look darker or more saturated because water temporarily changes how light passes through the pigment; after evaporation, the dried wash may appear lighter. The reliable method is to paint and dry a small test sample, then judge its final value before working on the artwork. Adding black every time can muddy the colour and is not a controlled solution.

Correct answer: B. When the amount of water is increased

Explanation: The governing concept is watercolour transparency and dilution. Watercolour pigment becomes visually lighter when more clean water is added, because the pigment is spread more thinly and the white paper reflects through the transparent layer. This produces a lighter value without adding white pigment. Thus option B is correct. Black generally darkens the mixture, a complementary colour can mute it, and red changes the hue rather than simply lightening it.

Correct answer: B. Evaporation of water can reduce visual intensity

Explanation: The governing concept is the change in perceived transparency and intensity as watercolour dries. While wet, the water film can make pigment appear stronger, darker, or more saturated. As water evaporates, the paper shows through more clearly and the dried layer may look lighter. Therefore option B is correct. Paper does not make pigment primary, a brush does not chemically change it, and white does not form automatically.

Correct answer: B. When clean water is added to watercolour

Explanation: The governing concept is the difference between dilution and tinting. Adding clean water to watercolour reduces pigment concentration, allowing more of the paper to show through; the result is lighter and more transparent, but no new white pigment has been mixed into the colour. Adding white to opaque paint creates a true tint, while black darkens and a complement alters intensity. Therefore option B is correct.

Correct answer: A. Gradually change the colour amount or white

Explanation: The governing concept of gradation is a controlled, gradual change in value or colour intensity. Prepare successive mixtures by slowly changing the amount of the base colour or white, then place the stages so each one connects smoothly to the next. Therefore option A is correct. Completely different bands create abrupt stripes, leaving paper wet is not a colour method, and unmixed paint cannot form a continuous transition.

Correct answer: A. Prepare intermediate mixtures between the two colours

Explanation: The governing concept is graduated blending. To move smoothly from one colour to another, prepare several intermediate mixtures, changing the proportion little by little at each stage. Applying these stages in sequence produces a gentle transition instead of a sharp boundary. A sudden change gives no gradation, while a black strip or thick white line interrupts the relationship between the colours. Thus, option A is correct; each mixture should be tested and adjusted on the palette first.

Correct answer: B. Prepare several intermediate value mixtures and apply them in sequence

Explanation: The governing concept is controlled value gradation. A smooth transition from dark to light is easier when several intermediate mixtures are prepared first and placed in an ordered sequence. Each step then differs only slightly from the next, so visible bands are reduced. Option B is correct. Mixing only the extreme values gives poor control, adding black everywhere muddies the colour, and excessive water weakens poster colour’s opacity and handling.

Correct answer: A. Hard joins may form at the edges

Explanation: The governing concept is controlled blending: a soft gradation needs neighbouring colour areas to remain workable while their tones are being connected. If every band dries completely, its edge becomes fixed and the next band cannot merge smoothly with it, producing a visible hard join. Therefore option A is correct. Transparency, torn paper, or a changed brush shape is not the normal result of simply allowing paint to dry.

Correct answer: B. Colour ratio, water amount and a dry sample

Explanation: The governing concept is reproducible colour mixing. A colour name is subjective, and a palette photograph may not show exact proportions or the final dried value. Recording the ratio of each pigment, the amount of water, and keeping a dry sample provides both process information and a physical reference. The brush size alone cannot identify the mixture, so option B is the complete record.

Correct answer: C. Amount of water

Explanation: The governing concept in a graded wash is controlled dilution. Increasing the amount of water gradually lowers the concentration of pigment, so each successive stroke appears lighter while the transparent character of watercolour is retained. Therefore, option C is correct. Black paint would darken the mixture, glue does not create a lighter wash, and paper thickness does not alter pigment strength.

Correct answer: D. Adding too much water in one step

Explanation: A graded wash depends on a smooth, measured change in pigment strength. If too much water is added at one stage, the pigment becomes suddenly diluted, producing a visible pale band instead of a gradual transition. Thus option D is correct. Even strokes and consistent paint strength normally support an even wash, while a flat surface alone does not cause this abrupt change.

Correct answer: A. Moisture of the paper and brush

Explanation: The governing principle of wet-on-wet painting is that moisture controls the movement of diluted pigment. The wetness of the paper and the amount of water held by the brush determine how far and how quickly the colour spreads. Therefore, option A is correct. Paper colour, brush price, and the painting title have no direct effect on pigment flow or edge control.

Correct answer: B. Allow the paper to dry slightly

Explanation: In wet-on-wet watercolour, excessive moisture reduces control because pigment travels rapidly through the damp paper. Allowing the sheet to dry slightly reduces its surface moisture and makes the next application more predictable. Hence option B is correct. Adding water or fully soaking the brush would increase spreading, and oil is not an appropriate watercolour control medium.

Correct answer: C. Creating clear shapes and details

Explanation: Wet-on-dry means applying moist paint to a dry sheet. Because the dry surface does not allow pigment to travel freely, the artist can control boundaries and produce sharp shapes, fine lines, and small details. Therefore option C is correct. Soft mist and free flowing effects are more associated with wet-on-wet, while soaking the paper describes preparation rather than the purpose of wet-on-dry.

Correct answer: D. By gently blending the edge with a clean damp brush

Explanation: The relevant correction method is controlled softening. A clean, slightly damp brush can draw a small amount of moisture along the hard boundary, allowing the existing pigment to blend gently before it fully dries. Thus option D is correct. Black paint changes the value, scratching damages the paper, and a dry brush generally does not supply the moisture needed to soften the edge.

Correct answer: A. Colour depth increases while the lower layer remains visible

Explanation: Transparent layering, often called glazing, builds colour gradually while allowing the earlier layer and the reflective white paper to remain visible. This creates greater depth, luminosity, and subtle variation without losing the transparent character of watercolour. Therefore option A is correct. Complete coverage and immediate opacity are opposite effects, and layering does not automatically erase every edge.

Correct answer: B. Green

Explanation: In transparent watercolour glazing, the upper yellow layer visually combines with the blue layer beneath it. Since blue and yellow are commonly understood as primary colours that produce green when mixed, the transparent overlap generally appears green, making option B correct. Violet requires blue with red, orange requires yellow with red, and red is not the expected result of this pair.
