Secondary colours

The governing concept is a tint. Green made by combining yellow and blue is a secondary colour in the traditional pigment model. Adding white does not change it into a primary colour or turn it red; instead, white increases the reflected light and produces a lighter version of the same colour, called a tint. Adding black would make green darker and create a shade. Therefore, the direct result is that green becomes lighter, so option B is correct.

The governing concept is the formation of secondary colours. In a basic pigment system, mixing two primary colours creates one secondary colour: red with yellow gives orange, yellow with blue gives green, and blue with red gives violet. Changing the relative amounts produces lighter, darker, or warmer-looking variations of that mixture. Hence option D is correct; the process does not produce only white, no new colour, or necessarily only neutral colours.

In the traditional subtractive colour model used for paints, yellow and blue are primary pigments, and their mixture produces green, a secondary colour. Orange is made from yellow and red, while violet is made from red and blue. Therefore, option A is correct because it matches the yellow-plus-blue mixing relationship on the colour wheel.

Within the traditional paint colour wheel, red and blue are primary colours. When they are mixed, they produce violet, which is classified as a secondary colour. Orange requires yellow and red, and green requires yellow and blue, so those alternatives do not fit the stated mixture. Thus option B is the correct result of combining blue and red pigments.

A colour made by mixing two primary colours is classified as a secondary colour. Orange comes from red and yellow, green from yellow and blue, and violet from blue and red. These are therefore the three standard secondary colours in the traditional colour wheel. Neutral, monochromatic, and achromatic describe different colour properties or schemes, not this group. Option B is correct.

A traditional three-primary colour wheel places the primary colours at equal intervals around the circle. This arrangement leaves space between each pair for the corresponding secondary colour: yellow and blue surround green, yellow and red surround orange, and red and blue surround violet. They are not grouped at one point or confined to one region, so option B is correct.

On the traditional colour wheel, green is placed between yellow and blue because it is produced by mixing those two primary pigments. Violet lies between red and blue, while orange lies between red and yellow. Red is a primary colour rather than the secondary colour formed by yellow and blue. Therefore, option C, green, is the correct answer.

In the traditional RYB pigment model, mixing two primary colours produces a secondary colour. Yellow combined with blue produces green. The other pairings help distinguish the distractors: red plus blue gives violet, red plus yellow gives orange, and red-orange is a tertiary colour rather than the direct result of yellow and blue. Therefore, option B is the only correct answer for this pigment-mixing calculation.

The governing concept is the RYB traditional pigment colour wheel. When red and blue primary paints are mixed, they generally produce violet, a secondary colour. Orange comes from red and yellow, while green comes from yellow and blue; yellow itself is one of the starting primary colours rather than the product of this pair. Since the question concerns paint pigments, not additive light, option C is the unambiguous answer.

The governing concept is the traditional pigment classification of primary and secondary colours. Red, yellow and blue are treated as primary colours because they are the basic set used in this school-level model. Green is made by mixing yellow and blue, so it is secondary rather than primary. Therefore, option D is correct; the other three are the recognised primary colours in this context.

The governing concept is the colour-wheel relationship between primary and secondary colours. In traditional school paint mixing, combining two primary colours produces a secondary colour: red plus yellow gives orange, yellow plus blue gives green, and blue plus red gives violet. Thus, option B states the basic relationship. The other statements either reverse the relationship, introduce an unsupported claim about white, or incorrectly deny the connection.

The governing concept is secondary-colour formation in the traditional pigment colour wheel. When blue and yellow pigments are mixed, they produce green, so green is placed between blue and yellow. Orange comes from red and yellow, violet comes from red and blue, and red is a primary colour rather than a secondary colour. Therefore, option C is correct.

In additive colour theory, red, green and blue are the primary colours of light. Mixing red light with blue light adds those two components and produces magenta, which is a secondary light colour. Green alone is a primary, red plus green produces yellow, and green plus blue produces cyan. Therefore option B is correct.

The governing concept is the traditional RYB pigment colour wheel. In this teaching model, yellow and blue are treated as primary pigments; mixing them produces green, a secondary colour. Orange is formed from red and yellow, while violet comes from red and blue. Cyan belongs more naturally to modern subtractive CMY terminology, so option A is the intended answer.

In traditional pigment colour theory, primary colours are not obtained by mixing other hues, while a secondary colour results from combining two primary pigments. Equal red and yellow produce orange, so orange is classified as a secondary colour. It is not neutral, because neutral colours are greys, black, or white, and “monochromatic” describes a colour scheme rather than a single colour category. Therefore, option B is correct.

The governing concept is colour purity during subtractive mixing. A secondary colour is made by combining two primary pigments, such as yellow and blue for green or red and yellow for orange. Residue from a third pigment, a dirty brush, or a contaminated mixing area introduces unwanted absorption and makes the result muddy. A clean brush and separate area prevent contamination. Therefore option B is correct; the other actions reduce control or add impurities.

The governing concept in traditional colour theory is colour mixing. A secondary colour is produced by combining two primary colours in suitable proportions: red and yellow make orange, yellow and blue make green, and blue and red make violet or purple. Therefore option A is correct. Mixing black and white produces grey, while water changes the consistency or lightness of paint rather than creating a secondary hue; repeating one colour creates no new colour.

The governing concept is the traditional artist’s colour wheel. Its primary colours are red, yellow and blue; mixing each pair produces the secondary colours orange, green and violet: red plus yellow gives orange, yellow plus blue gives green, and blue plus red gives violet. Thus option B is correct. Option A lists the primaries, option C lists neutrals, and option D combines colours that are not the standard secondary group in this traditional system.

The governing concept is traditional subtractive colour mixing in art. Red and yellow are both primary colours, and combining them produces the secondary colour orange; therefore option C is correct. Green results from yellow plus blue, violet results from red plus blue, and blue itself is a primary colour. Remember the three common pairs: red + yellow = orange, yellow + blue = green, and red + blue = violet.

Under the traditional art colour wheel, red and blue are primary colours whose mixture forms violet, so option B is correct. This is a secondary-colour relationship: yellow mixed with blue produces green, while red mixed with yellow produces orange. Yellow is not formed by this pair, and orange requires red plus yellow rather than red plus blue. The result may vary slightly in shade with different pigments, but violet is the standard school answer.

The governing concept is the formation of secondary colours from pairs of primary colours. Red and yellow combine to make orange, so option A is correct. Yellow plus blue produces green, and blue plus red produces violet. Green is already a secondary colour, not one of the three traditional primary colours used to make orange. Thus only the red-and-yellow pair gives the required result in this school-level colour model.

In the traditional colour-mixing model used in basic art education, yellow and blue are primary colours that combine to form the secondary colour green. Therefore option B is correct. Red plus blue produces violet, and red plus yellow produces orange. Orange plus red is not the standard pair of primary colours for creating green. The answer follows the colour-wheel rule that each secondary colour comes from a particular pair of primary colours.

The relevant colour-wheel rule is that secondary colours are formed by mixing two primary colours. Red and blue combine to produce violet, making option C correct. Red mixed with yellow gives orange, while yellow and blue give green. The pairs containing green are not the standard primary-colour pairs because green is already a secondary colour. In actual paints, the exact violet shade can depend on pigment strength, but violet is the accepted result here.

A secondary colour is produced by mixing two primary colours in the traditional art colour system. Green is made by mixing yellow and blue, so option D is the correct choice. Red, yellow, and blue are the three primary colours in this school-level model and are not made by mixing the other listed colours. The question asks for classification rather than a new mixture, but the formation rule confirms why green belongs to the secondary category.

The governing classification separates primary colours from secondary colours. Yellow is a primary colour in the traditional art colour system, so option C is correct. Orange comes from red plus yellow, violet from red plus blue, and green from yellow plus blue; therefore those three are secondary colours. The word “rather than” is important: the task is to find the one primary colour among three secondary-colour examples.
