Colour filling and blending

The governing principle is allowing wet paint and paper to settle without disturbance. Placing the drawing flat and letting it dry naturally helps prevent wet colour from running and reduces uneven warping of the paper. Therefore, option A is correct. Folding can crease the wet sheet, a wet cloth adds moisture, and rubbing can smear or remove the paint.

The governing concept is controlled and harmonious application of colour. Good work keeps the paint inside the intended outlines and changes gradually where one colour meets another, producing neat edges and a smooth transition. Thus option A is correct. Spilled paint, broken edges, one colour everywhere, or scratches indicate poor control or damage rather than successful blending.

The governing technique is directional brush control near an outline. Moving the brush parallel to the boundary keeps the stroke aligned with the edge, making it easier to stop at the correct place and prevent paint from crossing the outline. Therefore, option A is correct. This motion does not speed drying, thicken paper, or alter the brush’s physical size.

The governing principle of blending is controlled paint quantity. If too much paint remains on the brush, the colours may spread uncontrollably, form thick patches, or cover the intended transition. Gently wiping the brush on a cloth or tissue removes the excess while retaining enough paint for a smooth blend. Adding more paint, pressing hard, or folding the work cannot improve brush control.

The governing idea is gradual blending: a hard boundary should be softened by distributing a small amount of wet paint across the meeting area. Small circular strokes work gently in several directions, helping one colour merge into the next without leaving a sharp line. They are not methods for cutting paper, drawing a straight edge, or drying a painting, so option C is correct.

An even tone depends on keeping the paint mixture consistent. The ratio of colour to water controls concentration: more water generally produces a lighter wash, while more pigment produces a stronger or darker tone. Therefore, this ratio should not be changed while filling the area. Paper direction, the painting’s name, and the brush handle do not determine the mixture’s tonal consistency, making option D correct.

A useful colour-filling principle is to establish lighter areas before applying stronger dark colours. Dark paint can easily transfer to nearby regions or dirty a light area when the brush or hand moves across the surface. Beginning with light sections reduces this risk and makes later dark accents easier to place accurately. It does not make paper dry, enlarge the brush, or erase the drawing lines, so A is correct.

Wet-on-wet blending requires a light, controlled brush movement so that the colours meet gradually without excessive mixing or damage to the surface. The artist should adjust pressure and direction according to the transition being made, rather than scrubbing forcefully. Very fast or harsh strokes can spread paint unevenly; heavy circular strokes are not always appropriate; and irregular movement reduces control. Thus option A is correct.

Preparing the required colours in advance supports continuity and consistency. The artist can move from one area or colour to another without stopping to mix hurriedly, so the paint remains closer in tone and the transition is smoother. This is especially useful when adjacent wet colours must be joined. Preparation does not enlarge the paper, clean the brush automatically, or erase boundaries; therefore option A is correct.

A flat fill aims to produce an even, untextured area. Applying strokes in a consistent direction from one edge to the other helps distribute paint evenly and reduces visible gaps, random patches, and changes in pressure. Slightly overlapping adjacent strokes can improve coverage while preserving the same direction. Irregular circles, scattered strokes, or colouring only the corners cannot cover the rectangle uniformly, so A is correct.

A final visual check is part of good blending practice. Looking at the work from a short distance changes the viewing angle and makes harsh edges, streaks, gaps, or uneven transitions easier to notice than when examining one small area closely. The artist can then soften or correct the problem carefully. Dipping, folding, or rubbing a pencil may damage the surface and does not reliably assess the blend, so A is correct.

In colour theory, a tint is produced when white is added to a hue, increasing its lightness while retaining its basic colour identity. A shade is made by adding black, and a complementary colour is a colour relationship rather than a lightened mixture. Mixing white with a dark colour therefore creates a tint, making option B correct.

The governing colour-theory rule is that adding black to a hue creates a shade, which lowers its value and makes it darker. A tint is made with white, a highlight is a light area placed to show brightness, and a wash is a thin, diluted layer of paint. Since the question specifically describes black mixing, option C is the only correct answer.

The governing visual principle is value contrast: light and dark areas placed together separate forms and direct the viewer’s attention. A dark main figure against a lighter background gains emphasis and becomes the focal point, so option A is correct. The contrast does not make the figure disappear, remove the difference between colours, or automatically flatten the whole painting. Other design choices may affect depth, but the immediate effect here is prominence.

The governing principle is contrast between figure and ground. When hue and value are nearly alike, the boundary carries little visual difference, so the eye has difficulty separating the main figure from its background. Option B is correct. Similar colour does not automatically create a glow, change the thickness of paper, or make paint transparent. A stronger difference in value, hue, or saturation would improve the figure’s clarity.

The governing idea is control of pigment spread. On a dry surface, water and colour cannot travel freely into surrounding areas, so the painter can keep the fill inside a shape and preserve a cleaner edge. This does not guarantee transparency, cause paint to spread without a brush, or make it erase instantly. Therefore, clear and controlled edges are the main advantage.

The governing concept is value modelling. Lighter and darker versions of one colour, often called tints and shades, can represent the effect of light falling on different parts of an object. Their gradual arrangement creates highlights, middle tones, and shadows, making the object appear solid rather than flat. They do not clean a brush, cut paper, or refill a paint bottle, so option A is correct.

A natural colour transition is created by placing an intermediate hue between the starting and ending colours. Orange lies between yellow and red on the warm-colour part of the colour wheel, so yellow blended through orange into red produces a gradual sunset-like progression. Green, blue, black, and white do not provide the same direct warm transition. Therefore, sequence A is the most suitable.

The governing concept is controlled colour blending. Dark pigments usually have strong visual intensity, so even a small quantity can greatly change a light mixture. Adding the dark colour gradually lets the artist stop at the desired shade and preserve a smooth transition. Therefore, option B is correct. Options A, C and D are unrelated or false: colour strength does not damage the brush, dark colours are not always transparent, and drying is not the reason for careful measurement.

The governing concept is practical colour testing. Applying the mixture to a small sample and allowing it to dry reveals its actual final value, saturation, transparency, spread, and possible colour shift on that type of paper. This is more reliable than judging a label or wet paint in a container. Brush weight and folding the paper provide no evidence about the dried colour, so option A is the best procedure.
