Colour balance in posters

The governing design principle is visual hierarchy. If red is dominant, yellow and blue can support the main message through smaller areas, details, highlights, borders, or accents. They need not be removed or made equally dominant, because equal dominance may weaken the focal point. Hiding them completely also wastes useful contrast. Thus, option D provides the most suitable roles.

The governing concept is colour dominance in poster composition. A dominant colour is the one given the greatest visual emphasis through area, placement, contrast or repetition, so it attracts attention and establishes the poster’s main impression. Because the question states that red is the main colour while yellow and blue support it, red functions as the dominant colour. It is still a primary colour, but “secondary” describes colour formation, not compositional role. Option C is correct.

The governing concept is colour balance and hierarchy in composition. Red, yellow and blue can each attract strong attention. If all three are used excessively and in nearly equal amounts, no colour receives a clear dominant role; the viewer’s attention is divided and the composition may feel noisy or unbalanced. Equal use does not create colourlessness or complete neutrality, and calmness usually requires control rather than competing strong colours. Therefore, option D is correct.

The governing design concept is visual balance, which depends on the relative area, intensity, contrast, and visual weight of colours. A poster can use one primary colour as a dominant colour and the others as accents or supporting colours; equal areas are not compulsory. Using only red limits communication, while turning colours brown removes their intended contrast. Therefore, controlled proportion and intensity in option A give the best balance.

The governing design concept is visual hierarchy and colour balance. Primary colours are strong and attract attention, so using one as the dominant colour and the other two in supporting amounts helps the viewer identify the main message without visual confusion. Equal use everywhere can make the composition noisy rather than balanced. Using only red reduces variety, while covering colours with black removes their communicative role. Therefore, B is best.

The governing design concept is control of colour intensity through hierarchy and proportion. Primary colours are visually powerful, so applying every colour at full strength over large or equal areas can make a design harsh and overwhelming. Reducing the amount or intensity of supporting colours allows the main colour to remain clear while creating contrast and balance. Changing the outline or paper size does not directly regulate colour intensity. Hence, B is correct.

The governing concept is colour balance in poster design. Primary colours can be lively, memorable, and attractive to children, but they work best when shapes are clear, colour areas are controlled, and text has strong readability. Therefore option A is correct. Muddy colours reduce clarity, unreadable text defeats the educational purpose, and equal background and text values weaken contrast and make reading difficult.

The governing principles are dominance and visual hierarchy. Giving red the greatest area or strongest emphasis makes it the first colour noticed, while the smaller yellow and blue areas support rather than compete with it. This creates an intentional order of attention in the poster. Equal colour amounts would not communicate the same hierarchy, and the arrangement does not establish symmetry, texture alone or colourlessness. Option A is correct.

Readability depends strongly on contrast between lettering and its background. Yellow is usually light in value, while blue is generally darker, and their different hues can also create strong visual separation. Thus option A is correct: the letters stand out more clearly. The other options are false because yellow and blue are not the same, pigments do not automatically absorb each other completely, and blue does not always turn white.

A poster needs visual hierarchy so that viewers can quickly identify the main message, supporting information, and background. If red, yellow, and blue are all equally intense and occupy similar amounts of space, each may compete for attention, making the composition feel busy and weakening the focal point. This does not make the poster monochromatic or automatically neutral, and blue will not be the only visible colour. Thus option A is correct; varying dominance, area, or intensity can improve balance.

The governing design concept is value contrast, which means a clear difference between lightness and darkness. If the text is much lighter or darker than its background, the letter shapes separate easily and remain readable from a distance. Thus, option A is correct. Equal values reduce legibility, many letter colours distract, and maximum intensity alone does not guarantee readable text.

The governing design concept is contrast, which means making the lettering visually different from its background. Strong contrast, such as dark letters on a light field or light letters on a dark field, improves visibility and reading speed. Therefore, option A is correct. The other choices hide, dirty, or physically alter the poster and do not improve letter clarity.

The governing design concept is colour contrast. Complementary colours are opposite or near-opposite partners on the colour wheel, so placing them together produces a strong visual difference. That difference can make lettering, symbols, or an important image stand out and can increase a poster’s attraction when used in balance. Therefore option A is correct; the other choices concern materials or tools, not visual impact.

White raises the value of a colour and lowers the visual strength of the original hue. If too much white is added, the poster colour may become excessively light, pale, or less intense, so option A is correct. A darker result would require black or another dark pigment. White does not normally create a metallic surface or turn every colour green; those choices do not follow the governing mixing principle.

Adding black lowers the value and brightness of yellow. With too much black, the mixture can lose its clear yellow appearance and look dark, olive, or muddy, making option B correct. Black does not change yellow directly into pure blue or bright pink. Light orange would usually be approached by combining yellow with a suitable amount of red or orange, not by adding black. The exact appearance also depends on the pigments and their proportions.

A peach-like colour is a light, warm orange or pinkish-orange tint. Starting with orange and adding white lightens its value while preserving its warm hue, so option A is the suitable method. The amount of white should be adjusted gradually because more white produces a paler peach. Adding black to blue creates a dark tone, red to green tends toward a muddy neutral, and blue to violet does not create the required warm light colour.

Olive green is a subdued, yellowish green. A practical poster-colour method is to begin with green, add a little yellow to make it warmer, and then add a very small amount of black to reduce brightness; option A is correct. The black must be added cautiously because it can overpower the mixture. More white makes a light tint, red and blue tend toward violet or a dark mixed colour, and white added to yellow creates a pale yellow tint.

The governing design concept is readability through contrast and clear form. A title is easier to read when its colour differs sufficiently from the background and its letter edges are neat and well defined. Thus option C is correct. Smaller letters reduce visibility, identical title and background colours remove contrast, and wetting the background can cause bleeding rather than clarity.

The governing design concepts are unity, balance, and visual hierarchy. When too many unrelated colours compete, the viewer’s attention is scattered and the poster message becomes less clear. Reducing the palette and choosing one dominant colour creates order while supporting colours provide contrast, so option B is correct. Adding more bright colours or patterns increases clutter, and painting everything black removes balance rather than solving it.

The governing concept is complementary colour neutralisation. Blue is opposite orange on the colour wheel, so adding a tiny amount of blue lowers orange’s saturation and produces a more muted, balanced tone. Thus option D is correct. Adding more yellow or red generally strengthens or shifts the orange, while a large amount of white mainly raises its value and makes it lighter rather than truly neutralising its intensity. Add blue gradually because excess can make the colour muddy.
