Colour mixing

The governing concept is traditional subtractive colour mixing used with paints. Yellow and blue pigments absorb different portions of light, and their mixture is commonly perceived as green. Therefore option C is correct. Orange is generally made from yellow and red, while violet comes from red and blue. Brown may result from mixing several complementary or darker pigments, but it is not the expected two-colour answer here.

The governing concept is colour purity and controlled mixing. Rinsing the brush and changing dirty water prevents leftover pigment from contaminating the next colour, so the washes remain clear and bright. Therefore, option C is correct. Mixing all colours together or using dirty water introduces unwanted pigments and produces dull, muddy mixtures. Folding the paper affects its shape, not the cleanliness or brightness of the paint.

In the traditional school colour wheel, red and yellow are primary colours, and mixing them produces orange, a secondary colour. Therefore, option B is correct. Green results from yellow mixed with blue, and violet results from red mixed with blue; blue itself is not produced by combining red and yellow in this model. The exact shade may vary with pigment strength, but the expected result is orange.

According to the traditional school colour wheel, blue and yellow are primary colours whose mixture produces green, a secondary colour. Hence, option C is correct. Orange is formed from red and yellow, while violet is formed from red and blue. The precise green may become lighter, darker, or less vivid depending on the pigments and their proportions, but the standard expected result remains green.

In the traditional school colour model, red and blue are primary colours. Their mixture produces violet, which is a secondary colour, so option D is correct. Green is made by mixing blue and yellow, and orange is made by mixing red and yellow. The final violet may vary in warmth or darkness according to the pigments and proportions, but the established colour-wheel answer is violet.

The governing concept is the traditional primary-secondary colour relationship used in paint mixing. Yellow and blue are treated as primary colours, and their mixture produces green; therefore option B is correct. Yellow mixed with red produces orange, while blue mixed with red produces violet. The exact result can vary with pigments and proportions, but green is the standard school-level answer for this pairing.

The governing colour-theory concept is a tint. A tint is made by mixing a colour with white, which raises its lightness while retaining a relationship to the original hue. Therefore, option A is correct. Black generally lowers lightness and produces a shade, while brown changes the colour character rather than simply creating a lighter version. Oil is not the appropriate additive for making an acrylic tint and may interfere with the paint system.

The governing colour-theory concept is a tint: a colour mixed with white becomes lighter while retaining its basic hue. Therefore option C is correct. For example, adding white to blue produces a lighter blue rather than black or a darker version. Option A would be associated with adding black, not white. Option B is chemically and visually unrelated to the usual result, while option D confuses lightness with transparency; adding white generally makes paint more opaque, not transparent.

The governing colour-theory concept is a shade: adding black to a colour generally reduces its lightness and produces a darker version, so option D is correct. Black should be added gradually because a small amount can strongly change the mixture and excessive black may make the result dull. White produces a tint, not a shade, so option A is wrong. Mixing black does not automatically create white or a transparent layer, which rules out B and C.

The governing concept is the subtractive mixing of primary pigments. In the traditional school colour model, red and yellow are primary colours, and combining them produces orange, a secondary colour. The exact shade can vary with pigment strength and proportions, but it remains in the orange range. Green requires yellow and blue, violet requires red and blue, and blue is not formed by this pair. Therefore option A is correct.

The governing concept is traditional subtractive colour mixing with pigments. Red and blue are treated as primary colours in the school colour model; when they are mixed, they produce violet, a secondary colour. The precise result may lean toward purple or a darker violet depending on the pigments and their proportions. Green comes from yellow and blue, orange from red and yellow, and yellow is not produced by this pair. Thus option C is correct.

A palette provides a separate surface where colours can be combined, adjusted and checked before they are applied to the artwork. This allows the artist to prepare the desired hue and avoid spoiling the paper with an unsuitable mixture, so option B is correct. Palette mixing does not change the paper’s weight, alter the brush size or make a picture form automatically. Small test mixes improve accuracy.

Adding white to a colour produces a lighter version known as a tint, so option B is correct. The white should be added gradually because a small amount may change the value noticeably. Black generally makes a colour darker and creates a shade, while brown or dark blue will not normally lighten the original colour. The exact appearance also depends on the pigment and its concentration.

The governing concept is traditional subtractive colour mixing used in painting. Yellow and red are primary colours, and their mixture produces the secondary colour orange, so option B is correct. Green results from yellow mixed with blue, while violet or purple results from red mixed with blue. Blue alone is not produced by combining yellow and red. The exact shade of orange depends on the proportions and strength of the two paints.

The governing concept is the traditional colour wheel and secondary-colour formation. Blue and yellow are primary painting colours; when mixed, they produce green, so option A is correct. Purple is formed from red and blue, and orange is formed from red and yellow. Red is not obtained from this pair. The final green may appear lighter, darker, or more muted depending on the proportions, pigment strength, and amount of water used.

The governing colour-theory concept is the distinction among tint, shade, and tone. A tint is a lighter version of a hue, commonly produced by adding white to it. Therefore option A is correct. A shade is made darker by adding black, while a tone is generally made by adding grey or reducing intensity. “Mixing colours” is a broad activity, not the specific name for lightening one colour.

In colour theory, a tint is made by adding white to a base hue, so the colour’s value becomes lighter while its basic hue remains recognisable. Gradual addition allows a controlled series of lighter steps for blending or highlighting. A darker shade or tone is associated with adding black or a darker colour, while a complementary colour is located opposite on the colour wheel. Therefore, B is correct.

When many pigments are repeatedly mixed, they can reduce one another’s brightness and produce a muddy, greyish, or dull colour. The mixture does not automatically become white or brighter; white is associated with mixing light or with carefully controlled colour mixtures. Exam tip: Mix colours in small amounts and check the result before adding another colour.
