Colour Wheel and Colour Relationships

Correct answer: A. Complementary colours

Explanation: Red and green are complementary colours because they are positioned opposite each other on the traditional colour wheel. When placed together, they produce a strong visual contrast and can make each colour appear more vivid. Analogous colours sit next to one another, so red and green are not analogous. Green is a secondary colour, but red is a primary colour; therefore, option C is also incorrect.

Correct answer: A. Strong colour contrast

Explanation: Yellow and violet are complementary colours: on the traditional colour wheel, they are placed opposite each other. Their combination therefore creates strong colour contrast, and each may appear more vivid beside the other. They do not become colourless or automatically turn black, and the pairing clearly produces a visible difference. The effect is widely used when an artwork needs emphasis or visual energy.

Correct answer: C. Orange

Explanation: The relevant concept is warm and cool colour relationships. Red and yellow are generally classified as warm colours, and their mixture produces orange, which normally retains a warm, energetic appearance. Green is commonly associated with cooler qualities, violet can vary but is not the direct mixture of red and yellow, and grey is neutral rather than a secondary colour. Therefore orange is the correct answer.

Correct answer: B. Between yellow and blue

Explanation: The governing concept is the arrangement of primary and secondary colours on the colour wheel. Green is formed by mixing the adjacent primary colours yellow and blue, so it is placed between yellow and blue. Therefore, option B is correct. Red and yellow surround orange, while blue and red surround violet; those positions cannot identify green.

Correct answer: C. Blue and red

Explanation: The governing concept is the relationship between a secondary colour and the two primary colours that create it. Violet is made by mixing red and blue, so it occupies the position between red and blue on the colour wheel. Option C is correct. Yellow and blue produce green, and red with yellow produces orange; therefore options A and B describe other secondary-colour positions.

Correct answer: A. It is formed from red and yellow

Explanation: On a traditional colour wheel, orange is placed between red and yellow because it is made by mixing those two primary colours. Its position therefore communicates a mixing relationship between neighbouring colours. Yellow and blue produce green, while red and blue produce violet; black and white are not the parent colours of orange. Thus option A is correct.

Correct answer: C. Place it between yellow and blue

Explanation: The governing concept is the organisation of secondary colours on a colour wheel. Green is made by mixing the primary colours yellow and blue, so it is positioned between those two component colours. Red is not one of green’s component colours, and placing green at the centre would not show its hue relationship. Therefore, the correct correction is option C: place green between yellow and blue.

Correct answer: C. By the colour opposite it on the colour wheel

Explanation: The governing concept is complementary colour identification. On a traditional colour wheel, a complementary colour is found directly opposite the given colour, not beside it and not by changing its lightness. Orange lies opposite blue, so blue is orange’s complement. Adding white creates a lighter tint rather than identifying a complementary hue. Therefore, the correct method is stated in option C.

Correct answer: A. The colour becomes lighter

Explanation: The governing colour-theory concept is a tint: adding white increases a colour’s lightness. For example, mixing white with red produces a lighter pink tint, while the original hue remains recognizable. Therefore, option A is correct. Adding black generally creates a darker shade, not a lighter one. White does not automatically make poster colour completely transparent or metallic; those effects are not the normal result of this simple mixture.

Correct answer: A. To understand relationships and combinations of colours

Explanation: A colour wheel shows colours in an organised arrangement. It is used to understand relationships among primary, secondary, and complementary colours, and to select suitable colour combinations. Measuring paper and drawing straight lines are functions of a ruler, not a colour wheel. Exam tip: complementary colours are opposite each other on the colour wheel.

Correct answer: A. One

Explanation: A monochromatic colour scheme is built around one main colour, so option A is correct. The artist may create variety by using tints, shades and tones of that same colour: white makes a tint, black makes a shade, and grey or reduced intensity produces a tone. These variations do not turn the scheme into a two-, three- or four-colour scheme. The prefix “mono” means one.
