Colour mixing

The governing concept is correcting a mixture by changing the proportion of its component colours. Orange is produced from red and yellow; if it looks too red, adding a little yellow increases the yellow proportion and shifts the mixture back toward balanced orange. Therefore, option C is correct. Blue, violet, or black would make the colour duller, darker, or move it toward a different hue rather than simply correcting the red bias.

The governing concept is shifting a mixed colour toward one of its component hues. A yellow-green mixture can be moved toward blue-green by adding a small amount of blue, so option D is correct. Red or orange would introduce warm hues and could muddy the mixture, while white would only make the existing colour lighter without giving it the desired blue-green direction. The blue should be added gradually for control.

The governing concept is making a tint by lightening a warm base colour. Orange contains the warm red-yellow family, and adding white in a suitable proportion reduces its intensity and creates a pale peach-like appearance; therefore option A is correct. Black added to blue creates a dark blue shade, red added to green usually produces a dull neutral mixture, and yellow added to violet tends to neutralise rather than produce a clean peach tint.

The governing concept is creating a tint. When white is added to yellow, the pigment is diluted visually and the result becomes a lighter yellow, so option B is correct. Black would create a darker or duller yellow, blue would shift the mixture toward green, and red would shift it toward orange. The amount of white controls how pale the final yellow appears.

The governing concept is changing a tint by increasing the amount of its base hue. Pink is a light tint of red, so adding a little red increases pigment strength and makes the pink darker and redder; option C is correct. White would make it paler, yellow would shift it toward a warm orange-pink, and green could dull or neutralise it. A small addition is important because too much red would remove the pink quality.

The governing concept is tinting: adding white produces a lighter version of a colour. Therefore, option D is correct. White raises the apparent lightness while largely preserving the original hue when used carefully. Black would deepen the colour further, and brown or blue would mainly alter its hue and may make it duller rather than simply lighter. In practice, white should be added in small amounts because excessive white can make the mixture chalky.

The governing concept is proportion in colour mixing. Red and yellow combine to produce orange; when equal amounts of the two paints are used, neither colour dominates the mixture, so the result is generally a balanced or middle orange. Thus option C is correct. A green or blue bias would require another colour, and adding black would change the value rather than describe equal red-and-yellow mixing.

The governing concept is hue bias caused by unequal proportions. Blue and yellow normally mix to make green, but using more yellow shifts the mixture toward the yellow side of the colour wheel. The resulting colour is generally yellow-green, so option D is correct. Dark blue-green would show blue dominance, violet-green is not the expected result of only blue and yellow, and grey-green would require dulling or neutralising the mixture.

The governing concept is the effect of a dominant hue in a mixture. Red and blue produce a violet family colour; when red is used in greater quantity, the mixture shifts toward red and is described as red-violet. Therefore option A is correct. Blue-green needs blue and yellow, yellow-orange needs yellow and red, and light green needs a mixture involving yellow and blue rather than red and blue.

The governing concept is proportional influence during colour mixing. Red and yellow make orange, but adding more yellow shifts the hue toward yellow. The mixture is therefore generally yellow-orange, making option B correct. Red-violet requires red and blue, blue-green requires blue and yellow, and dark red is not the expected hue when yellow is the dominant partner in a red-yellow mixture.

The governing concept is hue direction in a two-colour mixture. Red and blue form violet; when blue is present in the greater amount, the violet shifts toward blue and becomes blue-violet. Hence option C is correct. Yellow-green requires yellow and blue, red-orange requires red and yellow, and light yellow is not produced by mixing a dominant blue with red.

The governing concept is controlled adjustment during colour mixing. Adding a small quantity at a time lets the artist observe each change and stop when the desired hue, value or intensity is reached. Therefore option C is correct. This method does not primarily dry the colour, dirty the palette or harden the brush; instead, it prevents adding too much pigment and makes correction easier.

The governing concept is clean colour mixing and avoidance of unnecessary pigment contamination. A muddy colour often results from overmixing or combining too many opposing pigments. Continuing to add colours, black or excessive water usually reduces clarity further. Therefore option D is best: start a fresh mixture on a clean palette, measure the needed colours carefully and mix only until the target hue is reached.

The governing concept is complementary colour mixing in subtractive paints or pigments. Complementary pairs lie opposite each other on the colour wheel, and combining them usually reduces saturation and brightness, producing a neutralised, muted brown, grey, or grey-brown result. Therefore option A is correct. A bright primary colour, pure white, or only pink is not the usual result of this mixture.

The governing concept is complementary mixing. In the usual paint or pigment colour wheel, red and green are complementary colours. When their pigments are mixed, each absorbs part of the light reflected by the other, so saturation and brightness decrease; the practical result is commonly a muted brown, grey, or brown-grey. Thus option B is correct, while the other choices describe bright or unrelated hues.

The relevant principle is complementary colour mixing. Blue and orange occupy opposite positions on the traditional colour wheel, so they are complementary. In paint, their pigments partially cancel one another and reduce saturation, usually producing a neutralised muted brown, grey, or brown-grey colour. Therefore option C is correct. Bright green, pure red, and light yellow are not the normal direct result of this complementary mixture.

The governing concept is the neutralising effect of complementary pigments. Yellow and violet are complementary colours because they are opposite on the traditional colour wheel. When mixed as paint, their combined pigments absorb more portions of visible light, lowering saturation and brightness and generally creating a muted brown, grey, or grey-brown colour. Thus option D is correct; the bright orange, light blue, and pure green choices are not expected outcomes.

The governing concept is tinting a light base colour. White provides a high-value, light foundation, and adding a small amount of yellow warms it and produces a soft cream-like appearance. Therefore option A is correct. Blue added to black remains very dark, red mixed with green becomes muted, and black added to violet makes it darker rather than cream. The exact appearance depends on the proportions and pigments used.

The governing concept is making a tint by increasing a colour’s lightness. Mixing white with brown raises its value and produces a lighter brown; the quantity should be added gradually so the desired shade is controlled. Therefore option B is correct. Black lowers value and makes brown darker, while blue or violet changes the hue rather than giving the simplest light-brown tint. This is a practical subtractive colour-mixing rule.

The governing concept is mixing black and white to create a neutral grey. Black contributes darkness and white contributes lightness; changing their proportion changes the value, so more white gives a lighter grey and more black gives a darker grey. Thus option C is correct. Red plus yellow makes orange, blue plus yellow generally makes green, and red plus white makes pink or a light red tint rather than neutral grey.

The governing concept is value controlled by mixing proportion. Grey is made from black and white, and increasing the proportion of white increases the mixture’s lightness or value. Consequently, light grey contains more white than black, so option D is correct. More black would produce dark grey, while red or blue would introduce a hue and no longer make a simple neutral light grey. Add black sparingly when adjusting the shade.

The governing concept is changing value by altering the black-to-white ratio. To make an existing grey darker, add a small amount of black and mix thoroughly; black lowers the lightness of the neutral mixture. Therefore option A is correct. Adding white would create light grey, while yellow or red would shift the hue away from neutral grey instead of simply darkening it. Small additions prevent the shade from becoming too dark too quickly.

The governing concept is recording and identifying a colour mixture during art practice. A label can state the colour name or the pigments used, helping the artist recognise the sample later and reproduce or compare the mixture consistently. Therefore option B is correct. Labelling does not change the paper’s weight, darken the paint, or clean a brush; those are unrelated actions. A labelled colour chart is especially useful for future reference.

The governing concept is systematic observation in colour mixing. A colour chart records or displays combinations such as two colours mixed in different proportions, allowing the learner to compare the resulting hues, tones, and shades. Therefore, option C is correct because it helps observe mixtures and their results. Cutting paper, hiding a painting, or drying colours is unrelated to the purpose of a colour chart.

The governing concept is reproducibility in colour mixing. The final appearance of a mixed colour depends greatly on which colours were used and how much of each was added. Recording a ratio, such as two parts yellow to one part blue, gives a practical guide for repeating the mixture. Thus option D is correct. Brush size, paper length, and the painting’s name do not specify the mixture itself.
