Colour mixing

The governing concept is building a light tint from a light base and warm pigments. White provides a pale value, while small amounts of red and yellow introduce warm red-orange or peach-like tendencies. Because the pigments are added gradually, the tone can be adjusted without becoming too strong; therefore option C is best. Blue and black darken or cool it, green and violet shift it away, and pure red is too intense.

The governing concept is reducing saturation for aerial perspective. Adding a small amount of grey lowers the colour’s intensity; a carefully chosen complementary colour can also neutralise it through subtractive mixing. A less saturated, quieter colour often suggests atmospheric distance, so option D is correct. Bright yellow, unchanged paint, or greater saturation would keep the object visually prominent.

The governing concept is systematic observation in colour mixing. A colour chart records the results obtained from different pairs of colours and different proportions, such as more yellow or more blue. By comparing the painted samples, a learner can remember how mixtures change and can select or reproduce a required shade. Therefore, option B is correct. It is not merely decoration, it does not make colours identical, and it cannot prevent paint from drying.

The governing concept is an intermediate colour produced by neighbouring hues. Yellow mixed with a small amount of red shifts slightly toward orange, so the resulting colour is yellow-orange and option B is correct. Because yellow remains the dominant colour, the mixture does not become full orange immediately. Green would require blue, blue-violet would require blue and red, and grey is not the expected result of this warm-colour mixture.

The governing concept is the influence of mixing proportion on an intermediate colour. Since blue is present in the larger amount, adding only a little red shifts blue toward violet without making it fully violet; the expected result is blue-violet, so option C is correct. Yellow-green requires yellow and blue, orange requires yellow and red, and brown is not the usual controlled result of this two-colour mixture.

The governing concept is colour bias caused by changing the mixing ratio. Green contains yellow and blue; when additional yellow is added, yellow becomes more dominant, so the green shifts toward yellow-green. Therefore, option D is correct. Adding more blue would move the mixture toward blue-green, while violet and red-orange require different colour combinations. The exact strength of the yellow-green depends on how much yellow is added.

The governing concept is the difference between a shade and a tint. Adding a small amount of black reduces the lightness of orange and produces a darker orange shade, so option A is correct. White would create a lighter tint, and extra yellow would shift orange toward yellow-orange rather than simply darkening it. Blue, the complementary colour of orange, may neutralise the mixture and make it dull or brownish, so it is not the best answer for a clean darker orange.

The governing concept is hue adjustment through controlled mixing. Violet already contains red and blue; adding a small amount of red increases the red component and shifts the colour toward red-violet, making it appear warmer and more reddish. Thus, option C is correct. Yellow or green would move the mixture away from a red-violet appearance, while black would mainly reduce lightness and may dull the colour rather than add red hue.

The governing concept is the formation of a shade: adding a small amount of black lowers the lightness of the original colour, so blue becomes darker and option D is correct. White would create a lighter tint. Yellow would shift blue towards green, while orange, its complementary colour, can reduce saturation and produce a dull or brownish mixture. Black should be added gradually because too much can overpower the blue.

The governing concept is subtractive pigment mixing and complementary colours. Red and green are opposite or near-complementary hues on a traditional colour wheel; when their pigments are mixed, each absorbs part of the light reflected by the other. The mixture therefore loses brightness and commonly appears brown, greyish, or dull, making option A correct. It does not normally produce pure blue, pink, or bright yellow.

The governing concept is complementary colour mixing. Blue and orange lie opposite each other on the traditional colour wheel. When their pigments are combined, they absorb a broad range of light, reducing saturation and brightness. The result is generally a neutral, greyish, brownish, or dull colour, so option B is correct. A bright green would require a blue-green combination, while pure red or light yellow is not the expected result.

The governing concept is complementary pigment mixing. Yellow and violet are opposite hues on a traditional colour wheel, so mixing them reduces chromatic intensity rather than creating a brilliant new hue. In ordinary painting, the mixture is likely to appear grey-brown, muddy, or otherwise neutral, making option C correct. Bright orange would require yellow and red, pure green would involve yellow and blue, and pink normally comes from red mixed with white.

The governing concept is value modification. When white is added to a pure colour or hue, the result is called a tint; it has greater lightness while retaining the basic colour identity. Therefore option D is correct. A shade is made by adding black, and a tone is commonly made by adding grey or a neutral. Complementary mixing combines opposite hues and is not defined simply by adding white. White should be added gradually to control the lightness.

The governing concept is the distinction between tint, tone, and shade. Adding black to a colour decreases its lightness and produces a shade, so option A is correct. A tint results from adding white, while a tone is generally produced by adding grey or another neutral colour. Complementary mixing means combining hues opposite each other on the colour wheel; it is not defined by adding black. In practice, black is best introduced in very small amounts.

The governing concept is the three-part distinction among tint, tone, and shade. Adding grey to a pure colour produces a tone, which reduces the colour’s intensity or saturation and often makes it appear softer or less vivid. Thus option B is correct. Adding white creates a tint by increasing lightness, while adding black creates a shade by lowering lightness. A complementary colour is a relationship between hues, not the direct result of adding grey.

The governing concept is hue adjustment and the formation of an intermediate colour. Orange already lies between red and yellow; adding a larger proportion of red shifts its hue toward red and produces red-orange. Therefore option C is correct. Blue and green tend toward blue-green, while yellow and green produce yellow-green. Mixing yellow with violet, a complementary pair, usually reduces brightness and creates a dull neutral rather than a clear red-orange.

The governing concept is intermediate-colour formation through hue proportion. Green mixed with a greater amount of blue shifts toward the blue side of the colour wheel, producing blue-green; therefore option D is correct. Red added to yellow tends toward orange, and white added to violet makes a lighter tint rather than blue-green. Blue mixed with orange combines complementary hues and generally becomes dull or neutral instead of producing a clean blue-green.

The governing concept is changing the proportion of a tint. Pink is normally a tint made from red and white. Adding a little more red increases the proportion of the base pigment and makes the pink darker, so option A is correct. More white would make a lighter pink. Blue or yellow could alter the hue toward violet or orange-greenish directions rather than simply deepening the same pink. The red should be added gradually for control.

Red and yellow are mixed to form orange, which is a secondary colour. The governing idea is colour bias: when one component is present in a greater amount, the resulting mixture appears closer to that component. Since red is used more than yellow, the orange shifts toward red and becomes red-orange. Hence option A is correct; yellow-orange would require more yellow, while the other choices involve different hue relationships.

Yellow and blue combine to produce green. The governing concept is proportion in colour mixing: the component used in greater quantity gives the mixture a stronger visual bias. Because yellow exceeds blue, the green shifts toward yellow and is described as yellow-green. Therefore, option B is correct. Blue-green would result from a larger amount of blue; red-green and grey-green are not the expected results of this two-colour ratio.

Red and blue combine to form violet. The governing concept is dominance of the larger component in a mixed hue. If blue is used in greater quantity than red, the violet mixture takes on a stronger blue bias and appears blue-violet. Therefore, option C is correct. Red-violet would require more red, while yellow-violet is not the expected name for this two-colour balance; brown would require a different, dulling mixture.

The governing concept is controlled proportion in practical colour mixing. Starting with small amounts lets the painter observe the change after each addition, preserve the intended hue, and correct an imbalance before too much paint is used. This is especially helpful when adding a strong or dark colour. Therefore, option A is correct; the other choices describe effects unrelated to measuring and controlling a mixture.

The governing concept is corrective adjustment of colour value. If a mixture is too dark, adding a suitable amount of white raises its lightness; adding a lighter version of one base colour can also adjust the result while retaining a related hue. Therefore, option B is correct. More black would darken it further, a large amount of complementary colour could muddy it, and an unclean brush would introduce contamination.

The governing concept is controlled colour mixing. Combining too many different pigments without a plan can introduce several competing colour biases; their pigments absorb and reflect light in ways that make the result dull, brownish, or muddy. Therefore, option C is correct. Adding only white creates a tint, using one primary colour does not create a complex mixture, and drawing a light line is unrelated to muddy paint.

The governing concept is colour testing or making a swatch before applying paint. A separate paper sample shows the mixture’s actual hue, value, opacity, and wet-to-dry change without risking the finished artwork. Therefore, option D is correct. The other choices describe no real effect of testing: it does not rename the colour, add weight to the paper, or change the brush length. This practice helps the artist adjust proportions safely.
