Contrast

Correct answer: A. Texture contrast

Explanation: The governing concept is texture contrast, which occurs when two surfaces have noticeably different tactile or visual qualities. A rough tree trunk beside soft-looking leaves creates a clear rough–smooth relationship, so option A is correct. Value similarity concerns lightness, proportion concerns size relationships, and repetition concerns recurring forms or spaces rather than surface quality.

Correct answer: B. There is not enough difference between the colours

Explanation: The governing concept is value contrast and visual readability. Yellow and white are both relatively light, so their lightness values are close; the letters do not separate clearly from the background. Therefore option B is correct. Large letters could improve readability, but size is not the main issue here. Shapes and straight lines do not create the needed foreground–background contrast.

Correct answer: C. Size and value contrast

Explanation: The governing principle is contrast, because the circle differs from the surrounding dots in more than one visual property. It is larger or thicker and also much darker, so both size and value contrast make it prominent. Option C is therefore correct. Rhythm may result from repeated dots, while unity and harmony describe relatedness or visual agreement; none alone explains the strong focal difference.

Correct answer: D. The object will be less clear

Explanation: The governing concept is subject–background contrast. When the main object and its background share the same colour, their visual difference becomes smaller, so the boundary and shape are harder to notice. Option D is correct because reduced contrast lowers clarity and weakens emphasis. Matching colour does not change the object’s actual size, automatically increase movement, or guarantee greater brightness.

Correct answer: A. Due to shape contrast

Explanation: The governing concept is shape contrast. A long rectangle has straight sides, corners, and an elongated contour, whereas the surrounding circles have curved, continuous outlines. This difference in external form makes the rectangle visually distinct, so option A is correct. Colour mixing and lighting could affect appearance in another situation, but they are not given as the distinguishing factor; symmetry alone also does not explain the contrasting contour.

Correct answer: B. Low visual clarity

Explanation: The governing concept is value contrast in lettering and design. Black and dark blue are both low-value, dark colours, so the letters have little lightness difference from the board and their edges are difficult to see. Option B is correct. The example does not create strong size contrast because no size change is stated, and it does not establish a bright warm–cool contrast either.

Correct answer: C. Line and value contrast

Explanation: The governing concept is contrast between line qualities. The single line is thicker than the others and darker in value, so it differs in both width and lightness and immediately attracts attention. Therefore option C is correct. Repetition may describe the surrounding thin lines, but it does not explain the exceptional line; uniformity would require sameness, and colour temperature is not relevant without warm or cool colours.

Correct answer: D. Keep the values of the main shape and background different

Explanation: The governing concept is value contrast, especially the dark–light relationship in a monochrome artwork. If the main shape and the background have different values, their boundary becomes visible and the shape receives emphasis. Option D is correct. Making everything the same grey removes contrast, erasing lines can reduce information, and making all shapes identical removes the distinction needed for a focal form.

Correct answer: A. Red and blue

Explanation: The governing concept is colour-temperature contrast. Red is commonly classified as a warm colour, while blue is commonly classified as a cool colour, so their pairing creates a clear warm–cool difference. Option A is correct. Red and orange, yellow and orange, and usually blue and green belong to neighbouring temperature groups, so they generally create less direct temperature contrast than red and blue.

Correct answer: B. It will appear more prominent

Explanation: The governing concept is contrast in colour intensity and saturation. Bright red is highly vivid, while grey is neutral and has little or no hue, so the red area differs strongly from its surroundings and attracts attention. Option B is correct. The contrast does not remove the red colour, change the area’s physical size, or make it less visible; instead, the neutral surround strengthens its visual prominence.

Correct answer: C. Contrast in spatial size

Explanation: The governing concept is contrast, which means a noticeable difference between visual qualities. Here, both areas are empty, so the relevant difference is not colour, texture, or line; it is the amount of space each occupies. A very large negative space beside a small negative space creates contrast in spatial size, making option C correct. The other choices would require differences in colour, surface quality, or line treatment.

Correct answer: D. Intensity contrast

Explanation: The governing concept is colour contrast based on intensity or brightness. When every colour has the same brightness, there is little difference in how light or dark the colours appear, so intensity contrast becomes low. Therefore option D is correct. Shape contrast would depend on contours, line contrast on line qualities, and space contrast on occupied or empty areas; none of those is determined by equal brightness.

Correct answer: A. A thick line beside a thin line

Explanation: Contrast is created when two visual qualities differ clearly. In option A, a thick line is placed beside a thin line, so the measurable quality being compared—line thickness—changes from large to small. That makes A the correct answer. Options B, C, and D retain the same thickness; their curvature or repetition may create other effects, but they do not demonstrate thickness contrast.

Correct answer: B. Low contrast

Explanation: The governing idea is that contrast increases with difference and decreases with similarity. Two shapes that are alike in form already have little visual difference, and placing them close together does not introduce a strong change in shape. Thus they create low contrast, making option B correct. High contrast would require clearly different forms, while temperature and texture contrast require differences in colour warmth or surface quality.

Correct answer: C. Texture contrast

Explanation: Texture describes how a surface looks or feels, such as smooth, rough, raised, or grainy. A mask with one smooth side and one raised side presents two clearly different surface qualities, so it demonstrates texture contrast. Option C is therefore correct. Value similarity concerns lightness and darkness, colour unity concerns colour relationships, and proportion concerns size relationships; none explains the surface difference described here.

Correct answer: D. Dark violet

Explanation: A symbol is easiest to see when it has strong contrast with its background. Yellow is relatively light, so it stands out poorly against light cream, light yellow, or white because their values are similar. Dark violet provides a strong light–dark difference and is also opposite yellow on the colour wheel, increasing visual separation. Therefore option D is correct; the other backgrounds reduce clarity through similarity.

Correct answer: A. Size contrast

Explanation: Size contrast occurs when elements differ noticeably in scale. Making the main shape larger than the surrounding shapes creates a clear size difference and also helps the main form attract attention. Thus option A is correct. Rhythm depends on repeated visual movement, harmony on a pleasing relationship, and colour mixing on combining pigments; none of those specifically explains the deliberate difference in size.

Correct answer: B. Moderately or less clear

Explanation: Value contrast is the difference between light and dark. Medium grey placed on light grey has some value difference, but the two tones remain relatively close, so the drawing will not appear strongly separated from the paper. It will look moderately clear or less clear, making option B correct. Complementary colour contrast requires opposing hues, and texture is unrelated to the closeness of the grey values.

Correct answer: C. One circle among triangles

Explanation: Shape contrast depends on a clear difference between contours or forms. In option C, the circle has a rounded contour while the surrounding triangles have pointed, angular contours, so the difference is immediately visible. Therefore C is correct. A, B, and D place identical or similar shapes together, producing repetition or low shape contrast rather than a strong change in form.

Correct answer: D. Focal point

Explanation: The governing design concept is emphasis: contrast can make one area stand out from the rest and attract the viewer’s eye first. The area receiving this primary attention is called the focal point, so option D is correct. A pattern is a repeated arrangement, a boundary marks an edge, and proportion compares sizes; these terms do not specifically name the dominant area of attention.

Correct answer: A. Due to value contrast

Explanation: The governing concept is value contrast, which means a difference between light and dark tones. A pale dewdrop reflects light and appears much lighter than the dark green leaf behind it, so its edge and surface become clearly visible. Therefore option A is correct. Shape, balance and proportion may describe other visual features, but none explains the strong bright-dark effect here.

Correct answer: B. The heading will not stand out

Explanation: The governing concept is contrast, especially colour and value contrast used for legibility. When red lettering is placed on a red background, the foreground and background have nearly the same visual identity, so their boundary is weak and the heading does not stand out clearly. Option B is correct. The colour does not enlarge the heading, turn the background white or alter line thickness.

Correct answer: C. Contrast of thickness and texture

Explanation: The governing principle is contrast between unlike visual marks. A very thin stroke and a broad stroke differ in width, pressure, edge quality and the amount of surface they cover. These differences create variety in thickness and can also produce contrasting texture, making option C correct. Colour harmony concerns related colours, symmetry concerns mirrored arrangement, and proportion concerns relationships of size rather than brush-mark variation.

Correct answer: D. Due to high light-dark contrast

Explanation: The governing concept is value contrast, the difference between light and dark areas. A bright object against a dark room has a strong tonal separation, so the eye notices it quickly and may treat it as a focal point. Option D is correct. The object need not be the largest or round, and the presence or absence of lines does not explain why its brightness attracts attention.

Correct answer: A. The main attraction

Explanation: The governing concept is colour contrast creating emphasis. Warm colours such as red, orange or yellow can appear visually active, while cool colours form a contrasting surrounding group. If only one warm colour is present among cool colours, its difference in temperature makes it noticeable and turns it into a focal point. Therefore option A is correct; it does not become a texture or a less visible area merely because of colour temperature.
