Tertiary colours

Correct answer: A. Blue-violet

Explanation: The governing concept is the effect of changing the proportion of a component colour. Violet moves toward blue when more blue is added, producing the tertiary hue blue-violet. Therefore option A is correct, and the dominant colour, blue, is named first. Red-violet would result from adding more red to violet, while yellow-orange and blue-green belong to different neighbouring colour relationships.

Correct answer: C. Red-violet

Explanation: The governing concept is hue movement caused by increasing one component in a mixture. Violet shifts toward red when additional red is introduced, creating the tertiary colour red-violet. Option C is therefore correct because red is the dominant direction of the mixture. Blue-green and yellow-green are formed around green, whereas yellow-orange is produced by shifting orange toward yellow, so those distractors do not fit.

Correct answer: B. Blue-green

Explanation: The governing concept is proportional mixing on the colour wheel. When blue is added in a greater amount to green, the mixture moves toward blue and becomes blue-green, a tertiary colour. Option B is correct because blue is the dominant direction. Yellow-green would require more yellow in green; red-orange and red-violet involve red and are unrelated to this particular mixture.

Correct answer: A. Yellow-orange

Explanation: The governing concept is hue proportion. Orange is produced from red and yellow; increasing the yellow component moves the mixture toward yellow and forms yellow-orange. Option A is correct. Red-orange would be obtained by adding more red to orange, while blue-green and red-violet use different colour pairs. On a traditional colour wheel, these intermediate hues are classified as tertiary colours because they lie between a primary and a neighbouring secondary colour.

Correct answer: A. They provide greater colour variety

Explanation: The governing concept is the artistic use of intermediate hues. Tertiary colours expand the palette between primary and secondary colours, allowing painters to show subtle changes, natural transitions and richer visual variety. Option A is correct. They do not erase colours, create only black, or make a painting colourless; those choices contradict the purpose of using a broader colour range in painting.

Correct answer: A. They show subtle colour changes in nature

Explanation: The governing concept is colour variation in observation and representation. Natural objects rarely appear as only pure primary or secondary colours; light, surface and surroundings create many intermediate hues. Tertiary colours help a painter represent those subtle shifts, so option A is correct. They do not restrict a scene to white objects, remove shadows, or create lines, because those choices describe neither colour mixing nor its visual purpose.

Correct answer: A. Colour wheel

Explanation: The governing concept is visual organisation of colour relationships. A colour wheel places primary, secondary and tertiary colours in order, making neighbouring mixtures and their positions easy to compare. Therefore option A is correct. A ruler measures or draws straight edges, an eraser removes marks, and a pencil can make sketches, but none of these tools alone shows the systematic relationships among hues as clearly as a colour wheel.

Correct answer: A. A colour made by mixing a primary colour with a neighbouring secondary colour

Explanation: The governing concept is the definition of a tertiary colour in the traditional colour wheel. It is formed by mixing a primary colour with the neighbouring secondary colour, such as yellow with green to make yellow-green. Option A is correct. Black and white create neutral values, two neutral colours do not define a tertiary hue, and the final option wrongly claims that mixing cannot produce it.

Correct answer: C. Six

Explanation: The governing concept is the structure of the traditional twelve-part colour wheel. It contains three primary and three secondary colours, with one intermediate tertiary colour between each adjacent primary-secondary pair. This gives six tertiary colours in total, so option C is correct. Three and four are incomplete counts, while twelve is the number of divisions in the full traditional wheel, not the number of tertiary colours.

Correct answer: B. Yellow-orange

Explanation: The correct answer is B, yellow-orange. In the traditional colour wheel, a tertiary colour is made by mixing a primary colour with the neighbouring secondary colour. Yellow is primary and orange is secondary, so their mixture produces yellow-orange. Red-orange comes from red and orange, yellow-green from yellow and green, and blue-violet from blue and violet; therefore those distractors do not match the given mixture.

Correct answer: B. Blue-green

Explanation: The correct answer is B, blue-green. A tertiary colour is produced by combining two neighbouring colours on the colour wheel, usually a primary colour and an adjacent secondary colour. Blue mixed with green gives blue-green. Yellow-green is made from yellow and green, blue-violet from blue and violet, and red-violet from red and violet, so none of those alternatives represents the stated mixture.

Correct answer: A. Blue-violet

Explanation: The correct answer is A, blue-violet. On a traditional colour wheel, blue and violet are neighbouring colours, and their mixture forms the tertiary colour blue-violet. Red-violet is produced by mixing red with violet, yellow-orange by mixing yellow with orange, and blue-green by mixing blue with green. Comparing each option with the two colours named in the question identifies A without ambiguity.

Correct answer: B. Red-violet

Explanation: The correct answer is B, red-violet. Tertiary colours are identified by combining neighbouring colours on the colour wheel. When red is mixed with violet, the resulting intermediate colour is red-violet. Yellow-green comes from yellow and green, blue-green from blue and green, and yellow-orange from yellow and orange. Those alternatives therefore name different mixtures and cannot answer this question.

Correct answer: A. Red-orange

Explanation: The correct answer is A, red-orange. A colour placed between two neighbouring colours on the colour wheel is often a tertiary colour named from both neighbours. Red-orange lies between red and orange and is made by combining those colours. Yellow-orange lies between yellow and orange, red-violet between red and violet, and yellow-green between yellow and green, so the other choices occupy different positions.

Correct answer: B. Yellow-orange

Explanation: The correct answer is B, yellow-orange. On the colour wheel, yellow-orange is the intermediate tertiary colour between yellow and orange. It results from combining those two neighbouring colours. Red-orange lies between red and orange, yellow-green lies between yellow and green, and blue-green lies between blue and green. Since the question specifies orange and yellow, only yellow-orange fits both the position and the colour mixture.

Correct answer: A. Yellow-green

Explanation: The correct answer is A, yellow-green. In the colour wheel, yellow-green is the tertiary colour located between yellow and green. It is formed by combining yellow with green. Blue-green lies between blue and green, red-orange between red and orange, and blue-violet between blue and violet. Therefore, although each distractor is a valid colour-wheel colour, only yellow-green occupies the position asked about.

Correct answer: B. Blue-green

Explanation: The correct answer is B, blue-green. A tertiary colour lies between two neighbouring colours on the wheel and is commonly named by joining their names. Green and blue combine to form blue-green, which occupies the interval between them. Yellow-green is between yellow and green, blue-violet between blue and violet, and red-violet between red and violet. Thus only option B matches both the specified pair and position.

Correct answer: A. Blue-violet

Explanation: The correct answer is A, blue-violet. Blue and violet are neighbouring colours on the traditional colour wheel, and the tertiary colour between them is called blue-violet. Red-violet lies between red and violet, blue-green lies between blue and green, and yellow-orange lies between yellow and orange. Checking the two boundary colours in the question therefore identifies option A as the only suitable answer.

Correct answer: B. Red-violet

Explanation: The correct answer is B, red-violet. On the colour wheel, red-violet is the tertiary colour positioned between red and violet, and it is formed by combining those two neighbouring colours. Blue-violet lies between blue and violet, red-orange between red and orange, and yellow-green between yellow and green. Consequently, only red-violet matches both the two colours named and the requested location.

Correct answer: C. Red-orange, yellow-green, blue-violet

Explanation: Tertiary colours are produced by combining a primary colour with a neighbouring secondary colour on the colour wheel. Red-orange, yellow-green, and blue-violet all follow this rule, so option C contains only tertiary colours. Option A lists primary colours, option B lists secondary colours, and option D lists neutral colours rather than tertiary hues.

Correct answer: B. One primary and a neighbouring secondary colour

Explanation: In traditional colour theory, a tertiary colour is formed by mixing a primary colour with the neighbouring secondary colour on the colour wheel, such as blue with green to make blue-green. Therefore, option B is correct. Two primary colours make a secondary colour, black and white make a neutral grey, and complementary colours are opposite rather than neighbouring hues.

Correct answer: A. Red

Explanation: Red-orange is a compound tertiary colour made from red and orange. In the conventional naming of such colours, the first named hue indicates the stronger visual influence or the slightly greater proportion. Thus, red is dominant in red-orange, making option A correct. Blue, green, and violet are not the dominant components named in this colour.

Correct answer: A. Yellow

Explanation: Yellow-green is a tertiary colour produced from yellow and green. The first part of the compound name conventionally identifies the hue with the greater visual influence, so yellow is considered more prominent than green in yellow-green. Therefore, option A is correct. Blue, red, and violet are not the dominant hues indicated by this colour name.

Correct answer: B. Blue

Explanation: Blue-green is a tertiary colour formed from blue and green. In the conventional compound-colour naming rule used here, the first named hue has the stronger influence; therefore, blue is dominant in blue-green and option B is correct. Yellow may be indirectly related to green in colour theory, but it is not the dominant hue named in blue-green. Red and orange are also unsuitable.

Correct answer: B. Blue

Explanation: Blue-violet is a tertiary colour positioned between blue and violet on the colour wheel. Its name begins with blue, indicating that blue has the stronger visual influence or proportion in the conventional school-level explanation. Therefore, option B is correct. Red is present indirectly within violet, but it is not dominant; yellow and green are unrelated choices here.
