Q. 1. What are related colour schemes? Explain with the help of a colour wheel.

Ans: By understanding and using a colour wheel you can create exciting colour schemes easily.

Colour Wheel

A colour wheel (also referred to as a colour circle) is a visual representation of colours arranged according to their chromatic relationship. Begin a colour wheel by positioning primary hues equidistant from one another, then create a bridge between primaries using secondary and tertiary colours.

These terms refer to colour groups or types:

Primary Colours: Colours at their basic essence; those colors that cannot be created by mixing others.

Secondary Colours: Those colours achieved by a mixture of two primaries.

Tertiary Colours: Those colours achieved by a mixture of primary and secondary hues. 

Basic Colour Combinations on a Colour Wheel are:

• Monochromatic

Analogous: Red and Orange, Blue and Green, etc. These are colours right next to each other on the colour wheel. They usually match extremely well, but they also create almost no contrast.

Complementary: Red and Green, Blue and Orange, Purple and Yellow. These are the colours directly across from each other on the color wheel. However they rarely look good when used together. They’re called “complementary” because, when used together, they become vibrant and have heavy contrast. Complementary colours are useful when you want to make something stand out. For example, if you use a green background and have a red circle on it, the red will jump off the page and be almost blinding. If you need a complementary colour to enliven a colour scheme, the colour wheel can help you do that. For example, you could use small ‘sparks’ of red-orange in a colour scheme that contains a lot of blue and turquoise.

• Triad.

• Split Complementary. 

Step 1-begin by choosing a “mother colour”.

Step 2-Using your “mother colour” as a starting point on the Colour Wheel; you’ll select and apply one of these Colour Palettes. This will give you the root Hues to work from.

Step 3-with the right combination you can then adjust the root Hues by making them lighter, darker and more or less intense. For example A basic colour wheel can also give ideas for combining hues from the same colour family (like bluish and yellowish greens, reddish and bluish purples…).

Q. 2. List the various factors influencing the choice of colours. Explain giving examples.

Ans: The most important aspect of colour in daily life involves aesthetic and psychological responses to color and influences art, fashion, commerce, and even physical and emotional sensations (People respond to different colours in different ways, and these responses take place, on emotional level. Colours are non-verbal communication. As you design embroidery it is helpful to keep in mind how the eye and the mind understand certain colours and the colour meanings attached with each colour. Colour scheme is a planned combination of colours. Factors influencing choice of colours:

(i) No two people see colour in exactly the same way; our eyes are all slightly different.

(ii) Different cultures create different ‘meanings’ for colours. These are traditions, not ‘the truth’. Nevertheless, your thoughts about a color do influence your response to it. For example, many Asian cultures associate the colour white with death and mourning, while Christians in the West use it for wedding dresses.

(iii) We experience our lives ‘in colour’. Colours will, in turn, bring back personal memories and the feelings we associate with them (Grandfather’s garden, a trip to the seaside, a favorite dress…). When you’re looking to apply colour psychology to the interior design of your home, you could draw on these memories and experiences to create a feel-good home.

(iv) Colour by Gender-for example gender difference is seen in the choice of yellow being preferred to orange by women and orange to yellow by men.

(v) Favourite Colour by Age Group-for example, is well liked by children, but begins to drop away by people as they become adults; With maturity comes a greater liking for hues of shorter wave length (blue, green, purple) than for hues of longer wave length (red, orange, and yellow).

(vi) Factors like mental health mood. age, occasion, season, type of clothing all affect the use of colours.

Q. 3. List the similarities and differences between complementary and split complementary colour scheme.

Ans: Complementary colours are colours that are opposite each other on the colour wheel, such as blue and orange, red and green, purple and yellow. Complementary colours balance as they are opposites-one warm, one cool. The high contrast between the colours creates a vibrant look, especially when used at full saturation. Complementary colours can be tricky to use in large doses.

Split-complementary color scheme: It is a colour scheme that includes a main colour and the two colours on each side of its complementary (opposite) colour on the colour wheel.

Q. 4. Consider the given situation then answer the following questions: 

Situation: a middle-aged man is wearing a navy blue three piece suit for an evening party.

(a) Name two different colours of the shirt in monochromatic colour scheme and analogous colour scheme.

(b) Name the complementary colour for tie and pocket-handkerchief.

Ans: 4a-Monchromatics: using one colour family in various values of intensities.

4b-Analogous: neighboring families on the colour wheel. Colour close to blue is blue-green, and green.

4c-Complementary: colours directly opposite each other on the colour wheel; thus in this case the colour of the tie and hanky for blue would be orange. 

Creating Tints and Shades


Adding white to a colour is known as a Tint


Adding black is referred to as a Shade

Q. 5. What is the relationship between primary, secondary and teritary colours? Using a colour wheel, show how tertiary colours are prepared.

Ans: The most widely used basic colour wheel starts with three primary colours: yellow, red, and blue. These three are taken as the starting point for mixing all other colours. Together they produce a neutral colour, usually a murky gray.

Primary Colours: Red, yellow, blue are. primary colours. When mixing these three colour hues, at least in theory, all the other hues of the colour wheel, including black can be created. Primaries express fundamental qualities, folk art, embroidery, costumes, etc.

Secondary Colours: Orange, green and purple, made from mixing the primaries: red and yellow make orange, blue and yellow make green, and red and blue make purple. These secondary colours are also known as complementary colours. These colours always go well with each other, hence the term complementary.

red+green = yellow

 green + blue = cyan 

red+blue = magenta or purple

Tertiary Colours: These colours are created when mixing one-secondary and one primary colour i.e. blue + violet = blue-violet. Three or more separate colours are mixed (one primary and one secondary – the combination of two primaries), and in our colour wheel each tertiary colour being created will be an equal combination of the two colours, left and right, surrounding an open segment. The tertiary colours are yellow-orange, red-orange, red-violet, blue violet, blue-green, and yellow-green.

red + yellow = orange

red + magenta = purplish red

green + yellow = yellowish green

green + cyan = blueish green

blue + cyan = greenish 

blue + magenta = purplish blue 

Primary, Secondary, Tertiary Colours: 

Primary Colours reds, greens and blues.

Secondary Colours yellows, violets (purples) and oranges.

Tertiary Colours Blends of the primary and secondary categories.

Q. 6. In a square of size 8 by 8 inches draw a composition of different geometrical shapes. Now colour the design in:

(a) Primary colours.

Ans: Primary colours:

(b) Tertiary colours.

Ans: Tertiary colours:
