Secondary colours

Correct answer: A. By keeping sufficient value contrast between text and background

Explanation: The governing design concept is value contrast: readability improves when the text is noticeably lighter or darker than its background. Secondary colours such as orange, green, and violet may be attractive, but hue difference alone does not always separate letters clearly. Equal lightness or equal value makes text blend into the background, while many different letter colours create visual confusion. Therefore, option A gives the most reliable correction.

Correct answer: A. Violet with white

Explanation: The governing concept is tint and value. Adding white to violet produces a lighter tint, which can represent a petal area receiving more light while retaining the flower’s violet identity. Much black creates a shade suited to a darker region, not the lit area. Green or orange changes the colour relationship and may muddy or neutralise the violet instead of simply increasing its lightness. Therefore, option A is the appropriate mixture for the highlighted part.

Correct answer: A. They should be free from the unwanted third colour

Explanation: The governing concept is pigment purity during colour mixing. A clean secondary colour forms when the two selected primary pigments do not contain traces of the third primary colour. For example, yellow and blue should be free from red contamination so that the mixture remains a clear green. Blackness, dryness, or lightness does not guarantee purity; therefore option A is correct.

Correct answer: A. Colour bias and variation

Explanation: The governing concept is proportion in pigment mixing. When the same two colours are combined in unequal ratios, the result shifts toward the colour used in greater quantity; for example, a mixture with more red becomes red-orange, while more yellow produces yellow-orange. This practice develops sensitivity to colour bias, variation, and control. It does not teach brush holding, paper folding, or renaming colours, so option A is correct.

Correct answer: A. It creates visual hierarchy in the composition

Explanation: The governing design concept is visual hierarchy. Selecting one dominant secondary colour gives the viewer a clear point of emphasis and helps establish the mood, while the other colours support rather than compete with it. A dominant colour does not erase the remaining colours, automatically make the work monochromatic, or alter the paper size. Therefore option A correctly describes the benefit.

Correct answer: A. Visual competition may increase

Explanation: The governing concept is colour balance and intensity. Orange, green, and violet are strong secondary colours; if each has equal area and full saturation, every colour demands similar attention. The composition may therefore feel restless or visually competitive. It will not automatically become neutral, turn the colours into primaries, or make only orange visible. Controlling area, value, or intensity can restore hierarchy, so option A is correct.

Correct answer: A. Mix the correct primary pairs and identify results at different ratios

Explanation: The governing concept is learning through application. A genuine practical test should require the learner to select the correct primary pairs, mix them, observe the resulting secondary colours, and compare how different ratios change the appearance. Merely writing names checks recall, while counting brushes or drawing only an outline checks neither mixing nor identification. Thus option A provides the strongest evidence of understanding.

Correct answer: A. A tint of green

Explanation: The governing concept is value modification by adding white. White increases the lightness of a colour without changing its basic colour family, so green mixed with white becomes a lighter green, called a tint of green. A complement is a contrasting colour, not a lightened version; the mixture does not become a new primary colour or black. Therefore option A is correct.

Correct answer: A. They are complementary colours

Explanation: The governing concept is complementary pigment mixing. Orange and blue lie opposite each other on the traditional colour wheel. When their pigments are mixed, each absorbs parts of the light reflected by the other, reducing chromatic intensity and often producing a muted or neutralised colour. They are not identical, both are not primary in the pigment model, and lightness is not the reason. Hence option A is correct.

Correct answer: A. Its value changes

Explanation: The governing concept is colour value, which describes how light or dark a colour appears. Adding white creates a lighter tint, while adding black or a darkening colour creates a darker shade; arranging both versions shows a value range for the same secondary colour. Its name does not simply change, it does not become primary, and it does not leave the colour wheel. Therefore option A is correct.

Correct answer: A. Mixing two primary colours

Explanation: The governing concept is the traditional pigment colour system. A secondary colour is produced by mixing two primary pigments in suitable proportions: red with yellow gives orange, yellow with blue gives green, and blue with red gives violet. White only changes lightness, black and white make a neutral grey, and layering one colour does not create a new colour family. Therefore option A is correct.

Correct answer: B. Orange, green, violet

Explanation: The governing concept is the classification of colours in the traditional pigment system. Orange, green, and violet are secondary colours because each is made by mixing two primaries: red plus yellow, yellow plus blue, and blue plus red. Red, yellow, and blue are the traditional primary group; cyan, magenta, and yellow belong to another printing model; black, white, and grey are neutral colours. Thus option B is correct.

Correct answer: C. Orange

Explanation: In subtractive pigment mixing, red and yellow are primary colours, and combining them produces the secondary colour orange. Because the quantities are equal, neither colour dominates, so a balanced orange is expected. Option C is correct. Green comes from yellow and blue, violet from red and blue, while brown may result from mixing several colours or from muddy, uneven mixtures.

Correct answer: A. Two primary colours combine to form a secondary colour

Explanation: In the traditional paint colour system, yellow and blue are treated as primary colours. When they are mixed, their pigments absorb different parts of white light and the remaining reflected colour is perceived as green, a secondary colour. Therefore option A gives the correct concept. The other choices incorrectly describe the colours as neutral or claim that one simply changes the other into white or black.

Correct answer: B. Yellowish green

Explanation: Green is made by combining yellow and blue. When more yellow and less blue are used, the yellow component dominates the mixture, so the resulting green shifts toward yellow and is called yellowish green. Option B is therefore correct. Bluish green would require a greater proportion of blue, while reddish or grey green would require another colour influence or a dulling agent.

Correct answer: C. Orange

Explanation: Red and yellow are generally classified as warm colours. Mixing these two primary colours produces orange, which is a secondary colour and usually retains a warm visual character. Therefore option C is correct. Green is made from yellow and blue, violet from red and blue, and blue itself is a primary cool colour in the usual classroom classification. The question concerns both colour formation and temperature.

Correct answer: B. Green

Explanation: Yellow and blue are the two primary colours combined to produce green in the traditional colour-wheel model. Consequently, green contains the visual influence of both components and is classified as a secondary colour. Option B is correct. Orange comes from red and yellow, violet from red and blue, and red alone is a primary colour, so none of those alternatives fits the stated pair.

Correct answer: B. Yellow and blue

Explanation: The governing concept is the arrangement of primary and secondary colours on the colour wheel. Green is a secondary colour produced by mixing the primary colours yellow and blue, so it is positioned between them. Orange is between red and yellow, while violet is between red and blue. Therefore, option B correctly identifies green’s position.

Correct answer: C. Violet — red and blue

Explanation: The governing concept is secondary-colour formation from pairs of primary colours. Red mixed with blue produces violet, so option C is correct. Yellow and blue produce green, and red and yellow produce orange. Therefore, option A gives the wrong pair, option B gives violet’s pair for green, and option D gives orange’s pair for green.

Correct answer: D. Yellow and green make violet

Explanation: In the traditional colour-wheel model, red, yellow, and blue are primary colours. Their pairs form the secondary colours: red plus yellow makes orange, yellow plus blue makes green, and red plus blue makes violet. Yellow and green do not form violet, so option D is the incorrect mixture. Green is already a secondary colour, not a primary component of violet.

Correct answer: A. Tint

Explanation: A tint is the lighter version of a colour produced by mixing that colour with white. This rule applies equally to secondary colours such as green, orange and violet, so option A is correct. Black would produce a shade, grey would generally produce a tone, and a complementary colour is identified by its position or relationship on the colour wheel rather than by adding white.

Correct answer: C. Shade

Explanation: In colour theory, mixing black with any colour creates a shade, meaning a darker version of the original colour. This remains true when the starting colour is secondary, such as orange, green or violet, so option C is correct. White creates a tint, grey generally creates a tone, and hue refers to the basic colour identity rather than the darkened mixture.

Correct answer: A. Add white

Explanation: Value describes how light or dark a colour appears. The most direct way to raise the value of a secondary colour is to add white, producing a lighter tint; therefore option A is correct. Adding black lowers the value and creates a shade. A complementary colour can dull or neutralise the mixture, while adding all three primaries does not provide a controlled method for lightening it.

Correct answer: B. Dark bluish violet

Explanation: A night scene is usually supported by darker values and cooler colour temperatures. A dark bluish violet suggests shadow, cool air and the subdued light associated with night, so option B is the most suitable choice. Light yellowish violet is warmer and brighter, while orange and light green can create strong contrast but do not best communicate the cool, dark atmosphere by themselves. The final choice may still depend on the painting’s lighting and composition.

Correct answer: A. The colours may visually compete

Explanation: The governing concept is visual hierarchy in a secondary-colour composition. Orange, green and violet are all strong secondary colours; if they receive equal intensity and equal attention, the eye may move between them instead of finding a clear focal point. This can make the composition feel busy or competitive. They will not become monochromatic or white, so option A is correct.
