Classification of colours is made on the basis of composition and effect.
(a) Classification on the basis of composition. Classification of colours on the basis of composition is as follows:
1. Primary colours. Red, yellow, and blue colours at the three ends of the triangle of colour chart are known as primary colours.
2. Secondary Colours. Secondary colours are formed by mixing two prim colours in the equal proportions. Green orange and purple colours in colour chart secondary colours.
Red + Yellow = Orange Yellow + Blue = Green Blue + Red = Purple
3. Intermediate Colours. When the primary colour is mixed with an adjacent secondary colour, an intermediate colour it formed. There are six intermediate colours. Yellow + Orange = Yellow orange Yellow + Green = Yellow green Blue + Green = Blue green Blue + Purple = Blue purple Red + Purple = Red purple Red + Orange = Red orange in this way, there are 12 colours in t colour chart-3 primary colours, 3 second' colours and 6 intermediate colours.
(b) Classification on the basis effect.
Classification of colours on the basis effects is as under:
1. Warm colours.
Red, yellow, orange colours on the left side of the colour chart warm colours. These are bright colours are give an effect of warmth. These have inspire and cheerful effects and also stimulate I person. The use of warm colours in an object leads to an illusion of nearness and vastness.
2. Cool colours.
Blue, green, and purple colours on the right side of the colour chart cool colours these colours give a feeling of coolness, lends peace to a person, and are gloom^ The use of cool colours in an object gives an illusion of farness and smallness.
Use of different colours in any artist creation is known as colour scheme. So (people have an inborn ability to use cool aesthetically. But for a common man, knowledge of different colour schemes is essential for proper colour combinations.
Standard colour schemes
1. Monochromatic colour scheme.
In this scheme, there is one base colour which is used in varied value and intensity. Though this colour scheme is simple yet there is a, possibility of monotony. For example, light blue salwar and dupatta with dark blue shirt.
2. Analogous colour scheme.
In this scheme, colours which are adjacent to each other on the colour chart are used.
3. Complementary colour scheme.
In this scheme, colours which are opposite to each other in the colour chart like red and green, yellow and purple, blue, and orange are used. For example, red sari with green border and blouse.
4. Double complementary colour scheme.
In this scheme, two secondary colours are used with two opposite primary colours.
While using these colours, care is taken that all the four colours are not of the same value and intensity and one colour should dominate the scheme.
5. Split complementary colour scheme.
In this scheme, a colour is used with the adjacent colour leaving its opposite colour. For example, blue green and yellow green when mixed with red.
6. Triad colour scheme.
In this scheme, three colours which are equidistant on colour chart are used. For example, green, purple, orange, yellow green, blue purple, and red orange.
The success of colour scheme in a dress depends upon its suitability on the person wearing it. It is not necessary that a colour that suits one person may suit other as well. Colour scheme in a dress should be according to colour of the skin, hair, eyes, personality, season, and occasion.
Colour of dress should match the accessories as well; otherwise, the purpose will be defeated. For example, in men, colour of suit should match with that of shirt, tie, socks, and shoes. Similarly, in ladies, the colour of sari should match with blouse, purse, sandals etc.
