Colour mixing

The governing concept is tertiary-colour formation on the colour wheel. Mixing a primary colour with a neighbouring secondary colour produces a tertiary colour, such as red mixed with orange to make red-orange, or blue mixed with green to make blue-green. Therefore option C is correct. White, black, and neutral colours are not the standard result of these adjacent colour combinations.

The governing concept is gradual colour mixing. Adding a small amount of one colour at a time lets the artist observe the change and stop when the desired shade is reached. This is especially important when adding a dark or strong pigment, because too much may be difficult to correct. Therefore, option B is correct; drying, brush size and paper thickness are unrelated.

The governing concept is colour purity during pigment mixing. A clean palette prevents dried or leftover paint from entering the new mixture, so the resulting hue remains close to the intended colour. For example, a trace of blue left on the palette can alter a yellow mixture. Thus option D is correct; cleaning the palette does not darken colours, save water, or stiffen a brush.

The governing concept is saturation, or colour intensity. Adding a little grey reduces saturation, while a small amount of the complementary colour partially neutralises the vivid pigment and makes it look quieter. Hence option C is correct. Adding more of the same colour increases the quantity but does not normally reduce its intensity; white paper and a dry brush do not alter the mixed pigment itself.

The governing concept is subtractive pigment mixing. Complementary pigments, such as red and green, absorb different parts of light and together reduce one another’s saturation. The mixture therefore often becomes dull, brownish, greyish or neutral, making option D correct. Greater brightness is associated with some light combinations, not pigment mixing; a pure primary colour or white does not normally result from this process.

The governing concept is systematic recording and repeatability in colour mixing. Writing the names or proportions of the colours beside a swatch creates a useful reference, allowing the artist to reproduce or adjust the result later. Therefore, option D is correct. A brush name or paper price does not identify the mixture, and guessing provides no reliable record. A labelled sample is both visual and practical evidence.

The governing concept is pigment mixing. When many paint pigments are combined, each pigment absorbs some wavelengths of light, so the mixture reflects less clean colour and loses saturation. As a result, it commonly appears dull or muddy. Therefore, option A is correct. It does not become extremely pure, automatically white, or only yellow; those results do not follow from combining many different pigments.

The governing concept is the effect of excessive pigment mixing. Repeatedly stirring several paints together combines their different absorbing properties and usually reduces clarity, brightness, and saturation. The result may look dull or muddy, so option B is correct. Overmixing does not transform the paint into a primary colour, make the palette white, or necessarily increase transparency; those alternatives describe unrelated results.

The governing concept is value, which describes how light or dark a colour appears. If poster paint becomes too dark, adding a small quantity of white raises its value and produces a lighter tint. Thus, option C is correct. Black would lower the value further, while adding a complementary colour may dull or change the hue rather than simply lighten it. The colour need not be discarded.

The governing concept is correcting a mixture by restoring its colour balance. Orange is produced from red and yellow. If the mixture contains too much yellow visually, adding a small amount of red shifts the balance back toward orange. Therefore, option D is correct. Blue may neutralise or muddy the mixture, green introduces another hue, and white only makes the colour lighter without correcting the yellow-red balance.

The governing concept is hue adjustment through controlled mixing. Green is commonly made from blue and yellow. If the mixture appears too blue, adding a small amount of yellow shifts it toward a more balanced or yellow-green appearance. Therefore, option A is correct. More blue increases the problem, black darkens the value, and red may neutralise or muddy the green rather than correct its blue bias.

The governing concept is learning through practical observation and controlled practice. Making regular colour swatches allows a learner to record proportions, compare results, notice changes in hue, value, and saturation, and repeat successful mixtures. Therefore, option B is correct. Memorising names alone gives little mixing skill, while using only black and white or never mixing prevents understanding how colours interact.

The governing concept is creating a tint by adding white to a hue. Red mixed with white becomes a lighter red, commonly called pink, so option A is correct. Orange requires red and yellow, violet is made from red and blue in traditional paint mixing, and brown usually results from combining several darker or complementary pigments. The amount of white controls how light the pink appears.

The governing concept is the traditional paint colour model in which pairs of primary colours produce secondary colours. Red combined with blue generally produces violet or purple, so option C is correct. Orange comes from red and yellow, while green comes from blue and yellow; yellow itself is not produced by mixing these two paints. Exact results can vary slightly with pigments, but violet is the expected school-level answer.

The governing concept is a shade: adding black lowers the value of a colour and makes it appear darker. When black is added to blue, the result is a darker blue, so option D is correct. White would create light blue by forming a tint, whereas green or purple require adding different hues rather than black. Only a small amount of black should be used because it can overpower the original blue.

The governing concept is tinting. Adding white increases the lightness or value of an existing hue, so violet becomes a lighter violet tint. Therefore, option B is correct. Adding black would create dark violet, while green and brown require adding or combining other pigments. The exact lightness depends on how much white is added, but the direction of change remains lighter rather than darker.

The governing colour-theory concept is a tint: a tint is made by adding white to a colour. Therefore, mixing white with green produces a lighter green, so option C is correct. Black would make a shade, usually a darker green; red could dull or neutralise the mixture; and blue would shift the hue toward blue-green rather than simply lightening it.

The governing concept is the difference between a tint and a shade. Adding a small amount of black to red makes a darker red, called a shade, so option D is correct. White would create a lighter red or tint. Yellow would move the colour toward orange, while green, the complementary colour of red, may neutralise it and produce a dull or muddy mixture.

The governing practical-art concept is the function of painting tools. A palette provides a smooth surface where paints can be placed, combined, and adjusted before they are applied to paper or another surface. Thus option A is correct. Scissors cut materials, a ruler measures or guides straight lines, and an eraser removes marks; none is intended for controlled colour mixing.

The governing studio-practice concept is preventing contamination. Paint left in the bristles can enter the next colour and change its hue, brightness, or purity. Washing and wiping the brush before mixing keeps the intended mixture clean, so option B is correct. Cleaning does not make the brush heavy, wet the paper as its main purpose, or dry paint faster.

The governing concept is the production of a neutral colour by combining black and white. Their mixture gives grey, so option C is correct. The exact value depends on proportion: more white produces light grey, while more black produces dark grey. Brown, green, and orange require different pigment combinations and cannot be made from only black and white in this basic mixing question.

The governing concept is colour proportion in a mixture. Yellow and red combine in the orange range; when the amount of red is increased, the mixture shifts toward the red side of orange. Therefore, red-orange, option D, is correct. Green and violet require different colour relationships, while blue is not produced by increasing red in yellow. The dominant component influences the resulting hue.

The governing concept is making a light tint by adding a small quantity of a stronger colour to white. A little yellow mixed into white produces a pale cream or creamy yellow, so option A is correct. Violet requires red and blue, dark brown needs darker pigment combinations, and blue-green requires blue with green or yellow in a different relationship. The result may vary slightly with the proportions.

The governing concept is the effect of dominance in a colour mixture. Blue and yellow normally produce green; when blue is present in the greater proportion, the resulting green shifts toward blue and becomes blue-green. Therefore, option B is correct. Yellow-green would result when yellow dominates, while red-violet and yellow-orange involve red and do not match this mixture.

The governing concept is tinting: adding white to any colour increases its lightness and produces a tint of that colour. Thus white added to orange gives light orange, making option D correct. A darker orange would require black or another darkening colour, not white. Brown and green change the hue through additional pigment relationships rather than simply making orange lighter.
